Oral Maxillofac Surg 2024; 28:485-497. [PMID: 37528316 DOI: 10.1007/s10006-023-01172-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2022] [Accepted: 07/10/2023] [Indexed: 08/03/2023]
Abstract
PURPOSE This systematic review and meta-analysis was performed to investigate if there was a significant association between the number of cigarettes smoked per day and the results of root coverage procedures. METHODS Electronic search was performed through PubMed, Web of Science, Embase, and Scopus until January 2023. Studies were included if evaluated the outcomes of periodontal plastic surgery procedures for the treatment of gingival recession in smokers. Statistical evaluation was conducted using random-effects method to analyze the odds ratio (OR) and mean difference (MD) with 95% confidence intervals (CI). RESULTS From a total of 4494 references, 15 studies were considered relevant to be included in this study. The results showed that 44.39% sites had complete root coverage (CRC) at 6 months (non-smokers: 54.06%, < 10 cigarettes/day: 48%, 10-20 cigarettes/day: 19.56%, ≥ 20 cigarettes/day: 50%). Mean root coverage at 6 months were as follows: non-smokers: 74.94% ± 16.71%, < 10 cigarettes/day: 84.20% ± 2.24%, 10-20 cigarettes/day: 75.30% ± 14.69%, ≥ 20 cigarettes/day: 68.75% ± 26.51%. A significant difference was revealed between non-smokers and individuals who smoked 10-20 cigarettes/day in terms of CRC at 6 months: OR = 0.15 (95% CI = 0.03 to 0.71; P = .017). However, no significant difference was detected comparing 10-20 and ≥ 20 cigarettes/day. CONCLUSION As there was not enough data available, any definitive conclusions about the connection between an increase in the amount of cigarettes consumed per day and the results of root coverage procedures could not be reached. Further research is required with comparative studies involving individuals who smoke varying numbers of cigarettes.

J Appl Oral Sci 2024; 32:e20230294. [PMID: 38747782 PMCID: PMC11093524 DOI: 10.1590/1678-7757-2023-0294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Revised: 02/24/2024] [Accepted: 03/12/2024] [Indexed: 05/19/2024] Open
Abstract
OBJECTIVE This study aims to develop a compound biomaterial to achieve effective soft tissue regeneration. METHODOLOGY Compound hyaluronic acid (CHA) and liquid horizontal-platelet-rich fibrin (H-PRF) were mixed at a ratio of 1:1 to form a CHA-PRF gel. Human gingival fibroblasts (HGFs) were used in this study. The effect of CHA, H-PRF, and the CHA-PRF gel on cell viability was evaluated by CCK-8 assays. Then, the effect of CHA, H-PRF, and the CHA-PRF gel on collagen formation and deposition was evaluated by qRT‒PCR and immunofluorescence analysis. Finally, qRT‒PCR, immunofluorescence analysis, Transwell assays, and scratch wound-healing assays were performed to determine how CHA, H-PRF, and the CHA-PRF gel affect the migration of HGFs. RESULTS The combination of CHA and H-PRF shortened the coagulation time of liquid H-PRF. Compared to the pure CHA and H-PRF group, the CHA-PRF group exhibited the highest cell proliferation at all time points, as shown by the CCK-8 assay. Col1a and FAK were expressed at the highest levels in the CHA-PRF group, as shown by qRT‒PCR. CHA and PRF could stimulate collagen formation and HGF migration, as observed by fluorescence microscopy analysis of COL1 and F-actin and Transwell and scratch healing assays. CONCLUSION The CHA-PRF group exhibited greater potential to promote soft tissue regeneration by inducing cell proliferation, collagen synthesis, and migration in HGFs than the pure CHA or H-PRF group. CHA-PRF can serve as a great candidate for use alone or in combination with autografts in periodontal or peri-implant soft tissue regeneration.

Allogenic Acellular Dermal Matrix and Xenogeneic Dermal Matrix as Connective Tissue Graft Substitutes for Long-Term Stability Gingival Recession Therapy: A Systematic Review and Meta-Analysis. Eur J Dent 2024; 18:430-440.

Abstract
Connective tissue graft (CTG) serves as a gold standard for gingival recession therapy. Yet the availability of CTG is limited, and it increases patient morbidity. Allogenic acellular dermal matrix (AADM) and xenogeneic dermal matrix (XDM) have been proven to be effective substitutes of CTG although the long-term stability is unclear. The aim of this study was to analyze the long-term stability outcome of gingival recession therapy using AADM and XDM compared to CTG. This study follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data were extracted independently from several online databases (PubMed, Scopus, and Embase). Five of 233 publications were included for final qualitative analysis and meta-analysis focusing on the mean difference of clinical parameters such as recession depth (RD), recession width (RW), probing depth (PD), clinical attachment loss (CAL), tissue thickness (TT), keratinized tissue width (KTW), and mean root coverage (MRC). Meta-analyses of RD, RW, CAL, TT, KTW, and MRC display an overall mean of 0.2 mm (95% confidence interval [CI]: -0.45 to -0.05), 0.29 mm (95% CI: -0.65 to 0.08), 0.2 mm (95% CI: -0.69 to 0.29), 0.25 mm (95% CI: -0.53 to 0.03), 0.26 mm (95% CI: -0.5 to 0.02), and 9.19% (95% CI: -13.95 to -4.43]), respectively, favoring the CTG. PD was the only parameter that favored the AADM or XDM with an overall mean of 0.03 mm (95% CI: -0.05 to 0.11). In all, if the long-term stability is the goal, the CTG is considered superior for gingival recession therapy. However, if it is contraindicated, the AADM and XDM might be considered as alternatives.

Abstract
AIMS This randomized trial assessed for the first time the efficacy of coronally advanced flap (CAF) followed by micro-needling (MN) in contrast to CAF with acellular dermal matrix (ADM) on gingival thickness (GT, primary outcome), keratinized tissue width (KTW), clinical attachment level (CAL), probing depth (PD), recession depth (RD), recession width (RW), recession reduction (Rec-Red), complete root coverage (CRC) and percentage of root coverage (all secondary outcomes) in management of RT1 gingival recession in patients with thin gingival phenotype. METHODS A total of 24 patients (n = 24) with a thin gingival phenotype and single RT1 gingival recession in the aesthetic zone were randomly allocated to test- (CAF + MN; n = 12) or control group (CAF + ADM; n = 12). All clinical parameters were evaluated at baseline, 3 and 6 months. RESULTS Both groups independently demonstrated significant gain in GT, RW, RD, CAL, PD, Rec-Red, CRC and percentage of root coverage, with reduced PI and BOP (p < .05) at 3 and 6 months, without intergroup differences (p > .05). At 6 months, KTW gain was significantly higher in CAF + MN (5.08 ± 0.9 mm) than in CAF + ADM-group (4.25 ± 1.06 mm; p < .05). Stepwise linear regression model with GT as dependent variable showed that base-line GT was the only statistically significant predictor for GT with a direct correlation between base-line GT and GT after 6 months. CONCLUSION CAF followed by MN could represent a promising graft-less approach for increasing gingival thickness, comparable to CAF with ADM, with superior keratinized tissue width improvement, in the treatment of RT1 recession defects in patients with thin gingival phenotype.

Abstract
Mucogingival surgery is a procedure for the treatment of gingival recession, which is a shift of marginal gingival tissue to the cementoenamel junction (CEJ), exposing the surface of the root teeth. One treatment for gingival recession is the Langer and Langer bilaminar technique, which involves the use of the fascia lata (FL) membrane. This membrane is harvested from the aponeurosis of the external muscles. The purpose of this case report was to present the clinical results of a 2-year follow-up using the Langer and Langer bilaminar technique modified with FL in a patient with gingival recession. Recessions are a shift of marginal gingival tissue to the CEJ, which exposes the surface of the root teeth. At the 2-year follow-up, the patient presented with a gingival recession in tooth 41, which resulted in complete root coverage, reaching 83.3%; the amount of keratinized tissue increased to 3 mm in each tooth, changing the gingival biotype from thin to thick and scalloped. This case report supports the use of FL as a successful alternative treatment.

Abstract
The goal of plastic periodontal surgery is to obtain complete root coverage, increasing gingival thickness (GT), a positive prognostic factor for gingival margin stability over time. The aim of this study was to compare the effectiveness of the Coronally Advanced Flap (CAF) in RT1 (GR; gingival recession with no loss of interproximal attachment) when associated with a connective tissue graft from the maxillary tuberosity (tCTG) or with leukocyte and platelet-rich fibrin (L-PRF) membranes in obtaining root coverage and increasing the thickness and width of the keratinized tissue, along with aesthetic improvement, taking into account a number of patient-related outcomes. Thirty patients with two adjacent RT1 GRs (GRs with no loss of interproximal attachment) were each treated using CAF associated with tCTG (15 patients) or L-PRF. The main outcome was a GT increase; secondary outcomes were keratinized tissue width (KT), gingival recession (GR), probing depth (PD), clinical attachment level (CAL), root coverage percentage (RC%), complete root coverage (CRC), and root coverage esthetic score (RES). Patient-reported outcomes were discomfort (D), dentine hypersensitivity (DH), patient-related esthetic score (PRES), and overall treatment satisfaction (OTS). After 12 months, clinical and patient-reported parameters did not show significant differences between groups, with the only exception being a GT gain, which was significantly greater in the CAF + tCTG group. Our results showed that both techniques were effective in treating RT1 GRs, with comparable patient-related outcomes. However, the use of tCTG produces significantly thicker tissue, covering the exposed root surface.

Abstract
OBJECTIVES To compare the clinical efficacy in terms of mean root coverage in RT2 recession treated with a coronally advanced flap combined with a xenogeneic collagen matrix versus a connective tissue graft. MATERIALS AND METHODS A total of 20 patients were randomized to receive one of two treatments: coronally advanced flap + xenogeneic collagen matrix (test group) and coronally advanced flap + connective tissue graft (control group). Patient-related outcomes measures and professional aesthetic assessment by root esthetic score were performed. A descriptive and analytical statistical analysis of the variables was performed. RESULTS At 12 months, the mean root coverage was 56.48% in the test group and 69.72% in the control group (p = 0.048), with a 35% and 40% complete root coverage in the xenogeneic collagen matrix and connective tissue graft, respectively. Test group presented less pain (3.65 vs. 5.2 VAS units) (p = 0.015) and less surgical time (45 vs. 49.15 min) (p = 0.004) than control group. CONCLUSION The use of xenogeneic collagen matrix in RT2 recessions was effective for recession reduction to those obtained using autologous grafts; with the advantage that the duration of surgery and patient morbidity decreased. Therefore, xenogeneic collagen matrix in RT2 recessions could be an alternative to autologous grafts. CLINICAL RELEVANCE The use of xenogeneic collagen matrix decreases the surgery time and patient morbidity but connective tissue graft results in significantly better mean root coverage and complete root coverage. Xenogeneic collagen matrix can be used in the treatment of RT2 gingival recessions. STUDY REGISTRATION NCT03344315.

Abstract
OBJECTIVE This study aimed to compare the efficacy of acellular xenogeneic dermal matrix graft (AXDM) compared to connective tissue graft (CTG) in treating multiple gingival recessions. MATERIALS AND METHODS A systematic search of electronic databases was conducted to identify randomized clinical trials (RCTs) that compared AXDM and CTG. The selected studies were subjected to bias risk assessment, data extraction, and meta-analyses. Parameters such as gingival recession height, width, mean percentage of root coverage, and complete root coverage were analyzed. RESULTS Seven RCTs involving 146 patients were included. The meta-analyses indicated that CTG was statistically superior to AXDM in reducing gingival recession height at the final follow-up (mean difference: -0.104 mm, 95% confidence interval [CI]: -0.180-0.028, p = 0.008) and width at the final follow-up (mean difference: -0.285 mm, 95% CI: -0.541-0.030, p = 0.029). CTG also demonstrated a significantly higher mean percentage of root coverage at the 6-month follow-up (difference in means: -2.761 mm, 95% CI: -4.932-0.590, p = 0.013) and a higher percentage of complete root coverage at the 6-month follow-up (odds Ratio [OR]: 0.598, 95% CI: 0.4-0.892, p = 0.012) compared to AXDM. However, there was no significant difference in the number of teeth with complete root coverage between CTG and AXDM (OR: 1.610, 95% CI: 0.983-2.636, p = 0.058) and aesthetic outcomes (mean difference: 0.148, 95% CI: -0.277-0.573, p = 0.494). CONCLUSIONS CTG is more effective than AXDM in treating multiple gingival recessions. This is evidenced by significant reductions in gingival recession height and width, a higher mean percentage of root coverage, and a greater percentage of complete root coverage at the 6-month follow-up. CLINICAL RELEVANCE In some clinical situations an alternative to CTG is required for the treatment of multiple gingival recessions. AXDM, despite presenting clinical outcomes that are not as satisfactory as CTG, can be used for this purpose.

Abstract
OBJECTIVE To evaluate root coverage (RC) in deep single antero-mandibular RT2 and RT3 gingival recessions (GR) and to investigate the influence of several factors in RC. MATERIALS AND METHODS Fifteen single antero-mandibular GR with a minimum depth of 3 mm were consecutively treated with a new one-stage technique (laterally positioned flap with a tunnel access and a connective tissue graft). At baseline and at 12-month follow-up, the percentage of mean root coverage (%MRC), the recession reduction (RecRed), complete root coverage (CRC) and the gain of keratinized tissue width (KTW) were assessed. Descriptive, intergroup comparative and correlation analyses were performed. RESULTS At 12 months, a %MRC of 77.29 ± 21.48% with a mean RecRed of 4.10 ± 1.51 mm was achieved. The %MRC was 84.71 ± 21.08% in RT2, and 62.43 ± 14.17% in RT3. The mean gain of KTW was 2.10 ± 0.89 mm, with a mean gain of 2.0 ± 1.03 mm for RT2 and 2.3 ± 0.57 mm for RT3. CRC was observed in six cases, all of them being RT2. A positive association was found between the %MRC and the initial position of the tooth and of both papillae. CONCLUSIONS This technique might be a valuable approach for the treatment of deep single antero-mandibular RT2 and RT3 recessions, even in malpositioned teeth. CLINICAL SIGNIFICANCE A combination of different surgical techniques could provide greater vascularization to the CTG especially in malpositioned teeth in sextant V with a large avascular area to be covered.

Long-term stability of gingival margin and periodontal soft-tissue phenotype achieved after mucogingival therapy: A systematic review. J Clin Periodontol 2024; 51:177-195. [PMID: 37963451 DOI: 10.1111/jcpe.13900] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2023] [Revised: 10/12/2023] [Accepted: 10/23/2023] [Indexed: 11/16/2023]
Abstract
BACKGROUND The aim of this systematic review was two-fold: (i) to evaluate the long-term (≥5 years) stability of the gingival margin position, keratinized tissue width (KTW) and gingival thickness (GT) in sites that underwent root coverage (RC) or gingival augmentation (GA); and (ii) to assess the influence of different local variables on the long-term stability of dental and gingival tissues. MATERIALS AND METHODS Randomized controlled trials (RCTs) and non-RCTs reporting short-term (i.e., 6-12 months after baseline surgical intervention) and long-term (≥5 years) follow-up data after surgical treatment of adult patients presenting single or multiple mucogingival deformities, defined as sites presenting gingival recession defects (GRDs) and/or (KTW) deficiency (i.e., <2 mm), were considered eligible for inclusion. MEDLINE-PubMed, EMBASE and Cochrane Central Register of Controlled Trials databases were searched for articles published up to 15 May 2023. Mixed-effects multiple linear regression was used to assess the association between KTW, type of surgical procedure and time (i.e., independent variables) on the stability of the gingival margin in sites that received RC or GA therapy. RESULTS Of the 2569 potentially eligible records, 41 (reporting 40 studies) met the eligibility criteria. Graphical estimates including data from all RC procedures found an upward trend in recession depth (RD) increase over time. Conversely, it was observed that in 63.63% of RC studies and in 59.32% of RC treatment arms KTW increased over time, particularly in sites treated with subepithelial connective tissue grafts (SCTGs). Conversely, sites that underwent GA procedures generally exhibited an overall reduction of KTW over time. However, sites treated with free gingival grafts (FGGs) showed a decrease in RD after 10 years of follow-up. Three main findings derived from the pooled estimates were identified: (i) Gingival margin stability was associated with the amount of KTW present during short-term assessment (i.e. the greater the KTW at 6-12 months after treatment, the more stable the gingival margin). (ii) The use of autogenous soft-tissue grafts was associated with lower RD increase over time. (iii) Treatment approaches that contribute to the three-dimensional enhancement of the gingival phenotype, as clearly demonstrated by FGG, were associated with gingival margin stability. CONCLUSIONS The extent of apical migration of the gingival margin appears to be directly related to the amount of KTW and GT upon tissue maturation. Interventions involving the use of autogenous grafts, either SCTG or FGG, are associated with greater short-term KTW gain and lower RD increase over time.

Abstract
BACKGROUND To evaluate and compare efficacy of pinhole surgical technique (PST) alone and with advanced platelet rich fibrin (A-PRF) in the management of bilateral multiple adjacent gingival recession defects (MAGRD). METHODS One hundred and sixty five MAGRD were randomly assigned to control group (treated with PST) and test group (PST with A-PRF). Clinical parameters of gingival recession depth (GRD), gingival recession width (GRW), width of keratinised gingiva (WKG), complete root coverage (CRC) and gingival thickness (GT) on ST-CBCT was measured at 2, 4 and 6 mm apically from the gingival margin. Also, root coverage aesthetic score and patient satisfaction ratings were recorded at baseline, 6 and 12 months postoperatively. RESULTS Substantial reduction in GRD (Test: 1.29 ± 0.69 mm and Control 0.98 ± 0.30 mm) (p < 0.001) and GRW (Test: 2.03 ± 0.90 mm and control 1.73 ± 0.99 mm) (p < 0.05) with associated gain in WKG and GT was observed (p < 0.001). Mean GT values were increased in both the groups at 2, 4 and 6 mm from the crest. Comparison of Test and Control groups yielded significant reductions in GRD (-0.17 ± 0.56 mm) and WKG (0.73 ± 1.07 mm) favoring the Test group (p < 0.05). Similar increase in GT was observed with better results in Test than control group. (p < 0.001). CONCLUSION Both groups exhibited sound clinical outcomes with test group offering better resolution of MAGRD in comparison to control group. Also, it enhances clinical and therapeutic end results in terms of attaining reduction in GRD and GRW along with greater gain in KTW and GT. CLINICAL SIGNIFICANCE PST as a minimally invasive approach has numerous benefits, some of which include the absence of scarring and improved aesthetics linked to faster wound healing. The addition of A-PRF enhances the intended therapy outcomes, which is beneficial for both patients and professionals in the field of periodontics.

Factors influencing intraoperative and postoperative complication occurrence: A series of 1135 periodontal and implant-related surgeries. Clin Exp Dent Res 2024; 10:e849. [PMID: 38345517 PMCID: PMC10847704 DOI: 10.1002/cre2.849] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2023] [Revised: 12/13/2023] [Accepted: 01/15/2024] [Indexed: 02/15/2024] Open
Abstract
OBJECTIVES In periodontology, it is widely recognized that evidence characterizing the incidence and effect of treatment complications is lacking. The objective of this study was to assess the influence of operator-, procedure-, patient-, and site-associated factors on intraoperative and postoperative complication occurrence. MATERIAL AND METHODS A single investigator reviewed records of patients treated by eight periodontics residents from July 2018 through June 2022. For each procedure, the investigator recorded each intraoperative and postoperative complication or indicated that no complication had occurred. These outcomes were analyzed against a panel of explanatory covariates. In addition, the severity of each postoperative complication was assessed using a standardized grading system. RESULTS A total of 1135 procedures were included in the analysis. Intraoperative and postoperative complications were identified in 2.8% and 15.2% of procedures, respectively. The most common intraoperative complications were Schneiderian membrane perforation (1.3%) and gingival flap perforation/tear (1%), and the most common postoperative complications were dentin hypersensitivity (2.6%), excessive pain (2.5%), and infection (2.2%). Subepithelial connective tissue graft (odds ratio [OR]: 3.2, 95% confidence interval [CI]: 1.6, 6.1; p < .001), guided bone regeneration (OR: 3.0, 95% CI: 1.4, 6.5; p = .004), and guided bone regeneration with implant placement (OR: 3.1, 95% CI: 1.3, 7.6; p = .011) were associated with higher odds of postoperative complication, whereas lateral sinus elevation (OR: 102.5, 95% CI: 12.3, 852.9; p < .001), transalveolar sinus elevation (OR: 22.4, 95% CI: 2.2, 224.5; p = .008), open flap debridement (OR: 36.4, 95% CI: 3.0, 440.7; p = .005), and surgically facilitated orthodontic therapy (OR: 20.5, 95% CI: 1.2, 358.4; p = .039) were associated with higher odds of intraoperative complication occurrence. CONCLUSIONS Consistent with previous reports, procedure type appears to be the predominant factor driving complication occurrence. As analyses of treatment complications increase, individualized risk-benefit assessments will become progressively meaningful for patients.

Abstract
OBJECTIVES This systematic review aims to evaluate the efficacy of combining the amniotic membrane (AM) with the coronally advanced flap (CAF) in the treatment of Miller class I and II gingival recession (GR). METHODS The protocol of this updated PRISMA-compliant systematic review was registered in PROSPERO (CRD42023431501). The following treatment outcomes were recorded; recession depth (RD), recession width (RW), width of keratinized gingiva (WKG), and clinical attachment level (CAL). We searched the following databases: MEDLINE, Cochrane Library, Google Scholar, EMBASE, Web of Science, and Science Direct. RESULTS Two independent reviewers screened the selected articles. Twenty-two eligible articles were extracted, with 689 sites of GR in 481 patients. No statistically significant difference was found in RD, RW, WKG, and CAL between (AM&CAF) in comparison to control groups. However, the subgroup analysis showed statistically significant differences in RD between the (AM & CAF) group v/s (CAF) alone (P = 0.004). Moreover, the subgroup analysis of the WKG showed statistically significant differences between (AM & CAF) v/s (CAF&CM) (p = 0.04). Additionally, a statistically significant difference was found in the subgroup analysis of CAL between both (AM & CAF) group v/s (CAF) alone (p = 0.0009). CONCLUSION With the limitations of this meta-analysis due to short follow-up periods (6 months), the AM can be considered a viable treatment option for GR defects with satisfactory treatment outcomes comparable to other previously investigated treatment modalities. CLINICAL SIGNIFICANCE While AM showed various beneficial properties as an ideal membrane for the coverage of GR, future studies are required to completely understand the potential application of AM in the treatment of GR.

The effect of smoking on clinical and biochemical early healing outcomes of coronally advanced flap with connective tissue graft: Prospective cohort study. J Periodontol 2024; 95:17-28. [PMID: 37436705 DOI: 10.1002/jper.23-0214] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2023] [Revised: 06/09/2023] [Accepted: 06/10/2023] [Indexed: 07/13/2023]
Abstract
BACKGROUND This study aimed to determine the effects of smoking on early (≤3 months) clinical outcomes and relevant molecular biomarkers following root coverage surgery. METHODS Eighteen smokers and 18 nonsmokers, status biochemically verified, with RT1 gingival recession defects were recruited and completed study procedures. All patients received coronally advanced flap plus connective tissue graft. Baseline and 3 month recession depth (RD), recession width (RW), keratinized tissue width (KTW), clinical attachment level (CAL), and gingival phenotype (GP) were recorded. Root coverage (RC) percentage and complete root coverage (CRC) were calculated. Recipient (gingival crevicular fluid) and donor (wound fluid) site VEGF-A, HIF-1α, 8-OHdG, and ANG levels were determined. RESULTS There were no significant intergroup differences for any baseline or postoperative clinical parameters (P > 0.05), except for whole mouth gingival index (increased in nonsmokers at 3 months; P < 0.05). Compared to baseline, RD, RW, CAL, KTW, and GP significantly improved postoperatively, without significant intergroup differences. There were no significant intergroup differences for RC (smokers = 83%, nonsmokers = 91%, P = 0.069), CRC (smokers = 50%, nonsmokers = 72%, P = 0.177), and CAL gain (P = 0.193). The four biomarker levels significantly increased postoperatively (day 7; P ≤ 0.042) in both groups and returned to baseline (day 28) without significant intergroup differences (P > 0.05). Similarly, donor site parameters were not different between groups. Strong correlations, consistent over time, were found between biomarkers implicated in angiogenesis (VEGF-A, HIF-1α, and ANG). CONCLUSIONS The early (3 month) clinical and molecular changes after root coverage surgery utilizing a coronally advanced flap plus connective tissue graft are similar between smokers and nonsmokers.

Abstract
PURPOSE To investigate the effect of xenogeneic collagen matrix (XCM) with polydeoxyribonucleotide (PDRN) for gingival phenotype modification compared to autogenous connective tissue graft. METHODS Five mongrel dogs were used in this study. Box-type gingival defects were surgically created bilaterally on the maxillary canines 8 weeks before gingival augmentation. A coronally positioned flap was performed with either a subepithelial connective tissue graft (SCTG) or XCM with PDRN (2.0 mg/mL). The animals were sacrificed after 12 weeks. Intraoral scanning was performed for soft tissue analysis, and histologic and histomorphometric analyses were performed. RESULTS One animal exhibited wound dehiscence, leaving 4 for analysis. Superimposition of STL files revealed no significant difference in the amount of gingival thickness increase (ranging from 0.69±0.25 mm to 0.80±0.31 mm in group SCTG and from 0.48±0.25 mm to 0.85±0.44 mm in group PDRN; P>0.05). Histomorphometric analysis showed no significant differences between the groups in supracrestal gingival tissue height, keratinized tissue height, tissue thickness, and rete peg density (P>0.05). CONCLUSIONS XCM soaked with PDRN yielded comparable gingival augmentation to SCTG.

Abstract
OBJECTIVE To develop a comprehensive decision-making tree for evaluating mid-facial peri-implant soft tissue dehiscence in the esthetic zone and provide a systematic approach for assessing various clinical case scenarios, determining appropriate treatment strategies, and considering factors such as the need for soft tissue augmentation, prosthetic changes, or implant removal. CLINICAL CONSIDERATIONS This clinical decision tree illustrates numerous case scenarios with various esthetic complications around an esthetically compromised, but clinically healthy single implant and provides clinicians with possible solutions as a predictable map for horizontal and vertical soft tissue augmentation in order to manage different clinical circumstances. According to current evidence, the key to treating such esthetic complications is the use of an adequate pre-surgical prosthetic interdisciplinary approach with proper surgical techniques in order to optimize soft tissue dimensions and create better esthetic results. This may be accomplished through a purely surgical, combination of surgical and prosthetic, or purely prosthetic approaches. CONCLUSIONS The present report describes a series of successfully treated peri-implant esthetic complication cases in accordance with the decision-making tree that the authors recommend in order to achieve better long-term esthetic outcomes. CLINICAL SIGNIFICANCE The combination of adequate pre-surgical prosthetic interdisciplinary collaboration and proper surgical technique is critical in the optimization of sufficient soft tissue dimensions and contributes to a more highly esthetic result. This study demonstrates a clinical decision-making tree to provide comprehensive, effective therapy of an esthetically compromised dental implant by using one of the following approaches: purely prosthetic, purely surgical, or a combination of surgical and prosthetic with or without abutment removal.

Abstract
OBJECTIVES The present study aimed to compare the influence of vertically coronally advanced flap (V-CAF) and free gingival graft (FGG) techniques on shallow vestibule depth (VD). MATERIALS AND METHODS Parallel-arm randomized clinical trial was conducted on 38 sites treated with either FGG or V-CAF. Periodontal variables (VD, recession depth and width, probing depth, clinical attachment level, keratinized tissue height (KTH), and tissue thickness (TT)), clinician- and patient-based subjective variables were assessed. RESULTS All periodontal variables showed significant improvements in both groups at all follow-up intervals compared to baseline (p < 0.05). Both groups increased VD compared to baseline. RC and CRC were similar after treatment for both techniques. FGG provided a greater increase in KTH (p < 0.001) and VD (VD1, p = 0.02 and VD2, p < 0.001) while V-CAF exhibited more TT gain (p = 0.002). Except overall tissue appearance that was better in V-CAF (p < 0.001), no inter-group significant difference existed in patient-based variables. CONCLUSIONS Both techniques were significantly effective in VD increasing. While both techniques were equally successful in RC, V-CAF provided higher TT gain and better tissue appearance. V-CAF can be chosen instead of FGG in the treatment of recessions with shallow VD. CLINICAL RELEVANCE It can be recommended to prefer V-CAF instead of FGG in the treatment of shallow vestibule.

Marques T, dos Santos NBM, Sousa M, Fernandes JCH, Fernandes GVO. Mixed-Thickness Tunnel Access (MiTT) through a Linear Vertical Mucosal Incision for a Minimally Invasive Approach for Root Coverage Procedures in Anterior and Posterior Sites: Technical Description and Case Series with 1-Year Follow-Up. Dent J (Basel) 2023; 11:235. [PMID: 37886920 PMCID: PMC10605838 DOI: 10.3390/dj11100235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 09/25/2023] [Accepted: 10/01/2023] [Indexed: 10/28/2023] Open
Abstract
PURPOSE The goal of this article was to introduce a new root coverage (RC) technique, the mixed-thickness tunnel access (MiTT) technique, which approaches a full-split design and intends to augment soft tissues coronal to the gingival margin. It was shown step-by-step, and the results were presented in a case series. METHODS Healthy individuals (non-diabetics) and non-smokers with gingival recession (GR) type 1 or 2 (RT1 or RT2) were included. After evaluation, prophylaxis was performed 14 days before the surgical procedure. During the surgical appointment, one or two vertical incision(s) on the mucosa (around 1-2 mm apical to the MGJ), lateral to the papilla base, was/were performed after anesthesia. Initially, there was a partial incision to detach the mucosa of the muscles (split design). It was permitted (but not mandatory) to perform intrasulcular incisions. Through the vertical incision, internally, subperiosteal access from the MGJ toward the gingival margin (coronally) was performed to create a full-thickness tunnel. Then, communication from the vertical incision with the gingival sulcus and the papilla base occurred, keeping the papilla tip intact. A connective tissue graft was harvested and inserted through the linear incision or intrasulcularly. There were interrupted sutures. An adjunctive material may be applied (e.g., Endogain). The root coverage was measured using a periodontal probe and considered fully covered when the gingival margin was 1 mm coronal to the cementum-enamel junction (CEJ). RESULTS Nine healthy individuals (seven females and two males) aged 19 and 43 were enrolled. They were treated following the MiTT steps. Four cases had a single GR; two patients had two teeth involved; and three others had three or four GR. There were seven cases of RT1 and two RT2. All RT1 cases achieved 100% RC, while the mean RC obtained for RT2 was around 80%. CONCLUSION The MiTT technique can be considered a more straightforward approach for minimally invasive surgical techniques, which is a feasible option to treat RC with a high success rate, predictability, and esthetic preservation. Therefore, there is a technical sensitivity to performing the full-split design procedure.

Does vestibular incision improve the outcomes of vestibular incision subperiosteal tunnel technique: A randomized clinical trial for treatment of multiple adjacent type 1 gingival recession. J ESTHET RESTOR DENT 2023; 35:1131-1138. [PMID: 37078417 DOI: 10.1111/jerd.13051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2023] [Revised: 03/27/2023] [Accepted: 03/31/2023] [Indexed: 04/21/2023]
Abstract
OBJECTIVE The purpose of this study was to compare the clinical outcomes of vestibular incision subperiosteal tunnel technique (VISTA) and tunnel approach combined with connective tissue graft (CTG) for treatment of type 1 (RT1) multiple gingival recession. MATERIALS AND METHODS Twenty-four patients with a total of 59 nonmolar recession teeth were randomly allocated to VISTA + CTG or Tunnel + CTG group. Recession depth and width, probing depth, clinical attachment level, width of keratinized tissue, gingival thickness, flap tension, mean root coverage (MRC), complete root coverage (CRC), patient-centered, and esthetic outcomes (root coverage esthetic scores, RES) were assessed at baseline and 12 months after surgery. RESULTS At 12 months, MRC of 91.13 ± 16.96% and 91.40 ± 13.53%, CRC of 70.97% and 67.86% were observed for VISTA + CTG and Tunnel + CTG group respectively, with no significant difference between the two groups (p > 0.05). High RES of 8.52 ± 1.46 and 8.82 ± 1.44 was obtained in VISTA + CTG and Tunnel + CTG group respectively, without showing a significant difference (p = 0.245), while less scar formation was observed in Tunnel + CTG group (p < 0.01). CONCLUSIONS Both procedures were effective for root coverage in RT1 multiple gingival recession at 12 months. Better esthetic result with less scar formation was obtained in tunnel approach combined with CTG without vestibular incision. (Registration number: ChiCTR-INR-16007845, registered on 19/12/2015, http://www.chictr.org.cn). CLINICAL SIGNIFICANCE VISTA + CTG and Tunnel + CTG were both effective for root coverage in RT1 multiple gingival recession, with satisfying esthetic outcomes. However, it is suggested in critical esthetic areas, treatment options of making vertical incisions should be carefully considered.

Multiple coronally advanced flap with a selective use of connective tissue graft: A 3-year prospective clinical and histological study. J Periodontol 2023; 94:1200-1209. [PMID: 37036093 DOI: 10.1002/jper.22-0632] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Revised: 02/15/2023] [Accepted: 03/29/2023] [Indexed: 04/11/2023]
Abstract
BACKGROUND The purpose of the present study was to prospectively evaluate the 3-year changes in the gingival dimensions following multiple coronally advanced flap (MCAF) with selective use of connective tissue graft (CTG). In addition, the secondary aim was to histologically identify the factors related to phenotype changes. METHODS Twenty patients treated with MCAF and site-specific application of a CTG were available for the 3-year follow-up. Outcome measures included complete root coverage (CRC), recession reduction, keratinized tissue width (KTW), marginal tissue thickness changes, and primary flap position. Biopsies were harvested at one of the sites treated with the adjunct of CTG. All sections were stained with hematoxylin and eosin, Masson trichrome, Verhoeff-van Gieson, tenascin, and alcian blue stain for semiquantitative evaluation. RESULTS At 3 years, CRC was detected in 86% of sites treated with MCAF alone and 81% of sites treated with MCAF + CTG. The 47% of sites treated with MCAF + CTG presented an apical shift of primary flap from its original position. Linear regression showed a significant association between KTW change and the initial KTW in MCAF-treated sites, while both initial KTW and position of primary flap were statistically significantly associated factors with KTW changes in the MCAF + CTG group. In all the biopsies examined, there is always a marked and clear separation between the connective tissue of the gingival flap and the palatal connective tissue of the graft. CONCLUSIONS The selective use of CTG is an effective treatment for multiple gingival recessions. Only a limited increase in KTW can be expected in a bilaminar technique if, during the healing phases, the connective tissue is maintained completely covered.

Abstract
BACKGROUND Orthognathic surgery is a reliable and safe method to improve maxillo-mandibular malformations. However, it is a complex procedure that can affect deeper structures and the terminal blood supply of specific areas, thereby affecting the results. Occasionally, despite careful digital planning and diagnosis, esthetic complications may occur, such as scarring or mucogingival alterations, including localized aseptic necrosis with associated recessions. In more severe cases, larger fragments of necrosis may be involved. METHODS AND RESULTS The aim of this case report was to present a case, including diagnosis, treatment plan, periodontal plastic surgical technique, and follow-up for a recession type 3 (RT3) defect. This RT3 gingival defect was associated with necrotic crestal bone exposure in the anterior esthetic area resulting from a complication after orthognathic surgery. CONCLUSIONS Partial reconstruction of the interdental papilla can be possible through consideration of the defect characteristics, use of microsurgical principles, and utilization of a suitable connective tissue grafting technique. KEY POINTS Why is this case new information? To the authors' knowledge, there is very limited clinical and scientific evidence regarding the management of esthetic complications associated with ischemic necrosis resulting from orthognathic surgeries. This case study identified the management of papillary reconstructions of these mucogingival defects. What are the keys to the successful management of this case? For an ideal case management, adequate plaque and infection control and timely notice of the defect appearance are critical. Additionally, proper surgical soft tissue management of the affected papillae and surrounding area is required. Finally, the type of connective tissue graft to be used, its management and fixation, and proper postoperative protocols are needed for case success. What are the primary limitations to success in this case? Despite the limitations of this study, the authors consider that the treatment of mucogingival complications related to orthognathic surgeries is possible, using microsurgical concepts and connective tissue grafts to reconstruct papillae.

Abstract
Objectives This umbrella review aimed to consolidate the best available evidence regarding the clinical efficacy of platelet derivatives in the treatment of periodontal defects associated with periodontitis and in the management of mucogingival deformities. Materials and Methods The "umbrella review" strategy was used to identify systematic reviews and meta-analyses. The search was performed without language restrictions and updated at the end of February 2023. The PubMed and Scopus databases, together with gray literature, were included in the search. Results The search yielded 412 studies. Subsequently, 12 articles were selected for further examination based on relevance. Finally, eight systematic reviews and meta-analyses were assessed. Regarding intrabony defects, in terms of clinical attachment level (CAL) gain, platelet-rich fibrin (PRF) was observed to lead to a statistically significant attachment gain compared to surgical therapy alone. PRF was also found to show greater CAL gain compared to platelet-rich plasma (PRP) and other biomaterials. The parameter probing depth decreased significantly when PRF was used compared to surgical therapy alone (P < 0.05). Similar results were seen when leukocyte- and platelet-rich fibrin (L-PRF) was applied. In terms of radiographic bone fill, both PRF and PRP showed significantly greater bone fill compared to surgical therapy. Regarding the results of periodontal plastic surgery, PRF favored a slight root coverage compared to the coronally displaced flap. This result depended on the number of PRF and L-PRF membranes used, but Emdogain or connective tissue graft produced better results regardless. However, an improvement in the healing of periodontal tissues was reported. Conclusions Therapies with platelet derivatives applied to intrabony defects provided superior regenerative results compared to monotherapies, except in the case of root coverage.

Abstract
OBJECTIVE The purpose of this systematic review and meta-analysis was to evaluate the effectiveness of periosteal pedicle graft (PPG) in terms of root coverage and patient related outcomes. To the best of our knowledge this is the first systematic review with meta-analysis on PPG. MATERIAL AND METHODS A comprehensive search was performed using electronic and hand searches upto January 2023. Primary outcomes were Recession depth Reduction (Rec Red), mean root coverage (mRC) and complete root coverage (CRC). Secondary outcomes were gain in width of keratinized gingiva (WKG) and patient reported outcome measures (PROMs). Meta-analysis was performed when possible. The risk bias assessment was done using RevMan5.4.1 and Joanna Briggs institute scale for the included RCTs and case series respectively. RESULTS A total of 8 RCTs and 2 case series (538 recession sites) were included based upon the predefined inclusion and exclusion criteria. The follow up period ranged from 6 months to 18 months. Results demonstrated that mRC of PPG + Coronally advanced flap (CAF) was 87.7% for localized gingival recession defects (GRDs) and 84.83% for multiple GRDs. An overall gain in WKG (Weighted Mean =1.49 ± 0.27 mm) was observed among all the included studies in the PPG + CAF group with mean difference (-0.10 (95% CI [-0.52, 0.33], p = 0.66)). Sub-group meta-analysis comparing PPG + CAF with sub-epithelial connective tissue graft (SCTG) + CAF resulted in similar outcomes in terms of Rec Red (0.10 (95% CI [-0.56 to 0.77], p = 0.76)) and gain in WKG (-0.03 (95% CI [-0.25 to 0.18], p = 0.76)). In terms of PROMs systematic review revealed better patient satisfaction with PPG + CAF than SCTG + CAF. CONCLUSION PPG + CAF is a viable treatment modality for management of GRDs. The primary and secondary outcomes achieved utilizing PPG + CAF were found to be comparable to other conventional techniques including the gold standard i.e., SCTG.

Abstract
Different types of errors and complications may arise during and after the execution of periodontal or implant-related procedures. Some of the most relevant, although also controversial, and less commented, causative agents of errors and complications are methodological biases and bad interpretation of the evidence. Proper assessment of the literature requires of solid clinical knowledge combined with a systematic approach built on the recognition of common methodological biases and the avoidance of interpretive errors to critically retrieve, dissect, and judiciously apply available information for the promotion of periodontal and peri-implant health. This review addresses common types of methodological bias and interpretive errors that can alter the reader's perceptions on the real effect and potential ramifications of the reported outcomes of a given therapeutic approach due to bad interpretation of the available evidence: (1) types of methodological biases; (2) spin and interpretive bias; (3) interpretation pitfalls when assessing the evidence (4) choice of relevant endpoints to answer the question(s) of interest; and (5) balance between statistical significance and clinical relevance.

Abstract
Root coverage procedures have become very common in clinical dental practice. Even though these techniques are considered safe, the clinician may face several issues during the therapy due to their surgical nature. Some of these issues can be defined strictly as complications inherent to the procedure, whereas others are medical errors or treatment errors. This review will focus on describing treatment errors and complications that may arise during different phases of the root coverage therapeutic process and on how to prevent and manage them.

Abstract
BACKGROUND Intra-marrow penetrations (IMPs) have been performed during guided tissue regeneration (GTR) procedures with reported clinical benefits. The aim of this systematic review was to investigate the use and effect of IMPs during root coverage procedures. METHOD A broad search for human and animal studies was performed on PubMed, Cochrane Database of Systematic Reviews and Cochrane Central Registry of Controlled Trials and Web of Science, following a registered review protocol (PROSPERO). All prospective study designs, case series and case reports on gingival recession treatment (follow-up ≥ 6 months) that employed IMPs were included. Root coverage, complete root coverage prevalence, and adverse effects were recorded, and risk of bias was assessed. RESULTS Of 16,181 screened titles, 5 articles (all of them human studies) met inclusion criteria. All studies (including two randomized clinical trials) treated Miller class I and II recession defects, using coronally advanced flap with IMPs alone or in conjunction with GTR protocols. Therefore, all treated defects received IMPs and no studies compared protocols with and without IMPs. Outcomes were indirectly compared with existing root coverage literature. Mean root coverage was 2.7 mm and 68.5% at 6.8 months (median: 6 months, range 6-15 months) for sites treated with IMPs. CONCLUSION IMPs are rarely used during root coverage procedures, have not been associated with intra-surgical or wound healing adverse effects and have not been investigated as independent factor. Future clinical studies are needed to directly compare treatment protocols with and without IMPs and investigate the potential benefits of IMPs for root coverage.

Abstract
This case series reports a modified tunnel technique with connective tissue graft for the root coverage of multiple Miller Class I, II, and III gingival recessions. The modified approach presents an innovative suture technique to improve the stability and position of the graft. Ten patients with multiple gingival recessions (n=85 teeth) received surgical root coverage treatment. The gingival recession height and width were measured and presented as median, minimum, and maximum values. The percentage of the root coverage after at least 12 months expressed the treatment effectiveness. The Shapiro-Wilk test evaluated the normality; pared Wilcoxon test determined the exact P-value for the differences in the height of the gingival recession before and after surgical treatment (α = 0.05). An average of 97.9% (± 5.6%, p < 0.0001) root coverage after treatment occurred, and 73 out of 85 recessions presented complete root coverage after 12 months. Treatment of Miller class I and II gingival recessions resulted in root coverage higher than 99 and class III higher than 95% (p < 0.0001). The presented case series report the efficacy of a modified surgical technique promoting more than 95% of root coverage after 12 months in multiple Miller Class I, II, and III gingival recessions. Well-designed blind randomized controlled trials are needed to validate the proposed technique.

Abstract
An esthetically pleasing smile is a valuable aspect of physical appearance and plays a significant role in social interaction. Achieving the perfect balance between extraoral and intraoral tissues is essential for a harmonious and attractive smile. However, certain intraoral deficiencies, such as non-carious cervical lesions and gingival recession, can severely compromise the overall aesthetics, particularly in the anterior zone. Addressing such conditions requires careful planning and meticulous execution of both surgical and restorative procedures. This interdisciplinary clinical report presents a complex case of a patient with esthetic complaints related to asymmetric anterior gingival architecture and severely discolored and eroded maxillary anterior teeth. The patient was treated using a combination of minimally invasive ceramic veneers and plastic mucogingival surgery, resulting in a successful outcome. The report emphasizes the potential of this approach in achieving optimal esthetic results in challenging cases, highlighting the importance of an interdisciplinary team approach in achieving a harmonious balance between dental and soft tissue aesthetics.

Morphological changes in alveolar bone thickness and height after orthodontic proclination or labial movement combined with autogenous soft tissue grafting: a CBCT evaluation. BMC Oral Health 2023; 23:218. [PMID: 37061689 PMCID: PMC10105956 DOI: 10.1186/s12903-023-02944-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2022] [Accepted: 04/05/2023] [Indexed: 04/17/2023] Open
Abstract
BACKGROUND Autogenous soft tissue grafting is indicated in thin gingival biotypes before orthodontic proclination or labial movements to increase the keratinized gingiva and prevent gingival recession. However, its effect on local alveolar bone remodeling is unclear. The aim of this study was to investigate the effects of autogenous soft tissue grafting on local alveolar bone after orthodontic proclination or labial movements. METHODS Sixteen patients with a thin scalloped gingival biotype, narrow keratinized gingiva, or thin cortical bone requiring orthodontic proclination or labial movement of teeth were included. Cone-beam computed tomography (CBCT) images were obtained before grafting and at least 6 months after surgery. Sixty mandibular teeth were included, and the vertical bone level and horizontal labial bone thickness were measured. The results were compared using paired t-tests or Wilcoxon signed-rank test. RESULTS The horizontal labial bone thickness increased, especially at 6 mm below the cementoenamel junction (CEJ) in the mandibular central and lateral incisors (P < 0.05). The total alveolar bone area of the canines, first premolars, and second premolars increased at 3, 6, and 9 mm below the CEJ, respectively, and the differences were statistically significant (P < 0.05). Additionally, vertical bone height increased minimally on the labial side, but the differences were not statistically significant (P > 0.05). CONCLUSIONS New bone regeneration was observed on the labial (pressure) side after autogenous soft tissue grafting, which may represent a mechanism to effectively prevent gingival recession and maintain periodontal health. IRB APPROVAL All the experimental procedures involving humans in this study were approved by the Medical Ethics Committee of Xiangya Stomatological Hospital, Central South University ( No. 20190048).

Abstract
OBJECTIVE To evaluate the efficacy of the partial-thickness non-advanced tunnel technique (TUN) versus the coronally advanced flap (CAF), both combined with a connective tissue graft, in the treatment of multiple gingival recessions. MATERIALS AND METHODS Twenty-nine patients (83 teeth) affected by multiple gingival recessions were treated in two clinical centers with either the test (TUN) or the control (CAF) intervention combined with a connective tissue graft. Outcomes at 3 and 6 months after surgery included complete root coverage (CRC-primary outcome), mean root coverage (mRC), changes in recession depth (RD), probing pocket depth (PPD), and keratinized tissue height (KT). Root sensitivity and root coverage esthetic score (RES) were also evaluated at 6-month examination. Surgery duration, wound healing index (WHI), and patient-reported outcome measures (PROMs) were additionally considered. RESULTS At 6 months, CRC was observed in 80.9% and 79.5% of the teeth treated with TUN and CAF, respectively (odds ratio = 1.2; p = 0.802). No differences between groups were also observed in terms of mRC (TUN = 94.0%; CAF = 91.1%), RD and PPD reductions, root sensitivity, RES, and WHI. KT increase was significantly higher in teeth treated with TUN (Difference in Means - MD = - 1.0 mm; p = 0.001). Surgery duration was shorter (MD = - 19.3 min; p = 0.001), and patients reported less intra-surgical pain (MD = - 16.4; p = 0.028) as well as postoperative morbidity in TUN compared with CAF. CONCLUSIONS Both surgical interventions showed a similar efficacy in terms of root coverage, albeit TUN was associated with a higher increase in KT and with a milder patient's surgical experience. CLINICAL RELEVANCE Both techniques have shown similar efficacy for the coverage of exposed root surfaces, although clinicians may consider TUN as less invasive.

Abstract
OBJECTIVE To compare the clinical outcomes of the tunnel technique (TUN) combined with either thin connective tissue graft (CTG) (TUN + thin CTG) (1 mm) or thick CTG (TUN + thick CTG) (2 mm) for the treatment of localized gingival recession (GR). MATERIAL AND METHODS Twelve patients, with 24 maxillary localized type RT1 GR were randomly assigned into two groups. Clinical, esthetic, and patient-reported outcomes were evaluated at baseline and at 6-month follow-up. RESULTS The TUN + thin CTG group showed a higher mean GR reduction (1.53 ± 0.66) (primary outcome variable) than the TUN + thick CTG group (1.44 ± 0.89), but no statistically significant difference was detected at the 6-month follow-up (p = 0.77). No statistically significant differences were found between TUN + thin CTG and TUN + thick CTG concerning complete root coverage (CRC) (58.3% versus 41.7%, respectively), gingival ticknness (GT) or Root-coverage Esthetic Score (RES) at 6 months. Regarding patient-reported outcomes, both groups reported having experienced similar pain at 7 days (p > 0.05). No statistically significant differences were found between the groups in the analysis of the aesthetic score. CONCLUSION Both treatments showed a similar reduction in GR. In addition, similar CRC, GT, RES, pain and self-reported esthetics were achieved in both groups. CLINICAL RELEVANCE Application of thin CTG provided a similar result than thick CTG for the treatment of RT1 localized GR.

Abstract
AIMS To analyse the histological structure and histomorphometric characteristics of human hard palatal mucosa in order to determine the donor site of choice for connective tissue grafts from a histological point of view. MATERIALS AND METHODS Palatal mucosa samples from six cadaver heads were harvested at four sites: incisal, premolar, molar and tuberosity. Histological and immunohistochemical techniques were performed, as was histomorphometric analysis. RESULTS In the current study, we found that the density and size of cells were higher in the superficial papillary layer, whereas the thickness of the collagen bundles increased in the reticular layer. Excluding the epithelium, the mean percentage of lamina propria (LP) and submucosa (SM) was 37% and 63%, respectively (p < .001). LP thickness showed similar values in the incisal, premolar and molar regions, and a significantly greater thickness in tuberosity (p < .001). The thickness of SM increased from incisal to premolar and molar, disappearing in the tuberosity (p < .001). CONCLUSIONS As dense connective tissue of LP is the tissue of choice for connective tissue grafts, the best donor site from a histological point of view is tuberosity because it is composed only of a thick LP without the presence of a loose submucosal layer.

Abstract
INTRODUCTION One of the most challenging aspects of treating gingival recession type 3 (RT3) is reconstructing lost interdental papillae, which is directly related to the loss of interproximal bone. Free gingival graft (FGG) has been successfully used to increase the keratinized tissue width (KTW) with minimal trauma to the interdental papilla. This presented case suggests that FGG can be used for reconstruction of lost initerdental papilla creeping attachment also plays an additional role in improving the results. CASE PRESENTATION The included two case reports suggest a novel technique using an FGG that is shaped in an inverted T-shape to achieve partial root coverage, improve the compromised interdental papilla, and increase the KTW in RT3 defects. CONCLUSIONS This report presents a novel yet intuitive surgical technique for partial coverage of RT3 defects and reconstruction of the interdental papilla. SUMMARY The inverted T-shape soft tissue graft may be a valuable technique for papillary reconstruction in the challenge of RT3 recessions. KEY POINTS Why is this case new information? Reporting innovative technique with the interproximal extension of the FGG that sutured lingually with the lingual marginal gingiva. Improve interdental clinical attachment phenotype and height. More predictable root coverage because of increased vascularized interproximal bed for the graft to be survived. What are the keys to the successful management of this case? Having at least 2mm interproximal space for graft survival. Good Extension with proper fixation of the lingual part of the graft, and stabilization of the graft. What are the primary limitations to success in this case? limited capacity for perfusion and survival of the lingual extension due to limited vascularity. More investigations are necessary to confirm the validity of this technique.

Abstract
INTRODUCTION Non-carious cervical lesions (NCCLs) can compromise the integrity to both hard and soft tissues of teeth. This case report introduces a novel interdisciplinary technique by utilizing bioceramics-based cement (BBC) and porcine collagen matrix (CM) to reconstruct the dentogingival complex where enamel, dentin, and soft tissues were involved. CASE PRESENTATION A 38-year-old healthy male was referred to the periodontics department for gingival recessions teeth #27-29 and a deep (NCCL) on the facial (F) #28 involving the loss of the cementoenamel junction (CEJ). The F #28 was restored with BBC according to manufacturing instructions. Soft tissues of #27-29 were simultaneously augmented with two CM strips via a coronally advanced tunnel utilizing suspended sutures. At the 6-month follow-up, approximately 100% root coverages were obtained for #27 and 29. The F #28 gingival tissue stabilized at the anticipated level of maximum root coverage (MRC), 1 mm apical to the coronally displaced CEJ. The exposed layer of BBC, F #28, was veneered with resin-modified glass ionomer to re-establish the original position of the CEJ. At the one-year follow-up visit root coverage for #28 remained stable and probing depths remained unchanged at 2 mm F #27-29. A sectional cone beam computed tomography scan illustrated the BBC restoration remained intact and well adapted. CONCLUSION The 12-month follow-up illustrated that the BBC may be a viable restorable material while performing simultaneous gingival grafting with CM in deep NCCLs with gingival recessions. KEY POINTS Why is this case new information? A novel approach treating the deep non-carious cervical lesion with BBC and CM. What are the keys to successful management of this case? The BBC placement needs to be flat. Secure the surgical site with non-resorbable suspensory sutures fixed by flowable composite. What are the primary limitations to success in this case? The primary limitation to success is the blood moisture control which may limit the placement of collagen matrix strips via the portal entry.

Abstract
INTRODUCTION Root coverage procedures are not always predictable, and outcomes depend on several factors. This technique provides a predictable alternative to managing facial gingival recessions. CASE SERIES A new grafting technique is introduced that requires no incisions at the recipient site, thereby preserving the integrity of the local blood supply to optimize the healing process. The graft is placed through the gingival sulcus via a molar or canine access (MOCA) approach, and there is minimal tension on the coronally advanced flap through use of suspension sutures. Thirteen non-smoking patients, between the ages of 27 and 57, with Cairo RT1 facial recession were studied, with a follow-up period of 1-60 weeks. This paper explains the step-by-step technique and highlights 13 cases. CONCLUSION Complete root coverage was achieved in all 13 cases, although one case showed initial altered healing. While MOCA is technique sensitive, it provides optimal root coverage results. With no incisions at the recipient site, there is no uneven texture or scar formation, and healing proceeds with minimal interruption. Why is this case series new information? MOCA is a unique approach to introduce grafts into non-incised sites of recession that can be one, two, or three teeth away at molars or canines. Non-incised approach minimizes interruption to blood supply. Coronally advanced flaps are secured in place with composite-fastened suspension sutures for tension-free flap closure. What are the keys to successful management of these cases? Good quality and quantity of connective tissue graft Early diagnosis and treatment of recession Expert surgical technique What are the key limitations to the success of these cases? The quality of the donor site is variable among patients. A technique-sensitive approach Advanced recession might warrant a second surgery.

Abstract
Minimally invasive surgical procedures aim at optimal wound healing, a reduction of postoperative morbidity and, thus, at increased patient satisfaction. The present article reviews the concept of minimal invasiveness in gingival augmentation and root coverage procedures, and critically discusses the influencing factors, technical and nontechnical ones, and relates them to the underlying biological mechanisms. Furthermore, the corresponding outcomes of the respective procedures are assessed and evaluated in relation to a possible impact of a minimized surgical invasiveness on the clinical, aesthetic, and patient-related results.

BACKGROUND The aim of this study was to evaluate clinical and patient-reported outcomes following surgical root coverage at RT1 gingival recession defects at mandibular incisors, using either a conventional free gingival graft (FGG) or a modified FGG (ModFGG). METHODS Total of 30 patients with RT1 gingival recessions at mandibular incisors were enrolled and randomly allocated to either a control (FGG) or test group (ModFGG). Evaluations of clinical changes (recession depth, height of keratinized tissue) and patient satisfaction were performed over a follow-up period of 12 months. Post-surgical changes of keratinized tissue height (shrinkage) were assessed from 1 month and onward. RESULTS ModFGG resulted in more pronounced root coverage at 1 year compared to FGG (91.8% vs. 60.7%, p < 0.001). Height of keratinized tissue was improved by 4.2 and 2.2 mm (p < 0.001), respectively, with significantly less shrinkage in ModFGG. Post-surgical morbidity was significantly lower for ModFGG at 2 weeks and patient satisfaction was significantly higher 12 months after treatment (9.1 vs. 5.4; p < 0.001). CONCLUSIONS ModFGG represents a valid approach for the management of RT1 recession defects at mandibular incisors. The technique is superior to traditional FGG in terms of root coverage, the gain of keratinized tissue height, and patient satisfaction.

Patient-reported outcomes of palatal donor site healing using four different wound dressing modalities following free epithelialized mucosal grafts: A four-arm randomized controlled clinical trial. J Periodontol 2023; 94:88-97. [PMID: 35754198 PMCID: PMC10087796 DOI: 10.1002/jper.22-0172] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2022] [Revised: 05/18/2022] [Accepted: 06/09/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND The aim of this study was to compare the effects of four different commonly used wound dressings in improving patient reported outcomes (PROMS) after free epithelialized mucosal grafts (FEGs) harvesting. METHODS Following 72 FEGs harvesting from 72 patients, patients were assigned into four groups. CONTROL collagen plug + sutures (CPS); test: collagen plug with cyano-acrylate (CPC), platelet rich fibrin (PRF) + sutures, or palatal stent only (PS). Patients were observed for 14 days, with evaluation of pain level utilizing the visual analog scale, number of analgesics consumed, need for additional analgesics, amount of swelling, amount of bleeding, activity tolerance, and willingness for retreatment. RESULTS Compared to the control group all test groups indicated significant lower pain perception (P < 0.0001), lower analgesic consumption (P < 0.0001), and higher willingness for retreatment (P < 0.0001), while no statistically significant differences among test groups were observed. There were no statistically significant differences in amount of day-by-day swelling, bleeding, and activity tolerance among four groups. Compared to other groups, the PS had the lowest overall pain scores (over the 14-day period). Palatal thickness, graft length, graft width, and graft thickness did not appear to affect patient morbidity (P > 0.05). CONCLUSIONS All interventions significantly decreased pain perception compared to a hemostatic collagen sponge alone over the palatal donor site after FEG surgery. In the first few days after surgery, the use of a palatal stent seemed to be associated with less overall pain, pain pills consumed, and higher willingness of doing the same procedure again.

Abstract
This case report presents a novel approach for root coverage of multiple gingival recessions with a volume-stable collagen matrix functionalized with injectable platelet-rich fibrin (i-PRF). A patient with multiple gingival recessions in the anterior maxilla was submitted to root coverage by coronally advanced flap with split-full-split incisions. Blood collection was performed before surgery and i-PRF was obtained after centrifugation (relative centrifugal force (RCF) 400 g, 2700 rpm, 3 minutes). A volume-stable collagen matrix was soaked with i-PRF and applied as a substitute for autogenous connective tissue graft. A mean root coverage of 83% was observed after a 12-month follow-up period, and only slight modifications were detected in a 30-month follow-up consultation. The association of a volume-stable collagen matrix with i-PRF successfully treated multiple gingival recessions with reduced morbidity since a connective tissue collection was avoided.

Abstract
OBJECTIVES The aim of this review is to address the potential applications of allogenous dermal matrix (ADM), as an alternative to subepithelial connective tissue graft (SCTG), in promoting periodontal phenotype modification (PPM) of challenging periodontal-orthodontic clinical scenarios. OVERVIEW The rationale behind the need of changing thin to thick gingival tissues is associated to the superior and more stable treatment outcomes promoted by PPM therapy. PPM, via soft tissue grafting, leads to clinical and histological changes of the pre-established original genetic conditions of the gingiva. Although SCTG-based procedures are recognized as the "gold standard" for the treatment of sites requiring root coverage and gingival augmentation, ADM has been recognized as the most suitable alternative to SCTG, particularly in clinical scenarios where the use of autogenous grafts is not possible. Thus, ADM is considered an optimal option for the treatment of patients with a history (or in need) of orthodontic tooth movement, due its two-fold potential indication: (1) the promotion of periodontal soft tissue phenotype modification; and (2) its use, as a barrier membrane, in hard tissues augmentation procedures. CONCLUSIONS ADM is a viable option for soft tissue augmentation, as well as for treatment approaches involving buccal bone gain. CLINICAL SIGNIFICANCE Periodontal phenotype modification therapy, when applied in challenging periodontal-orthodontic clinical scenarios, promotes root coverage and prevents the onset and development clinical attachment loss.

Abstract
AIM The aim of the current study was to compare the esthetic results for subjects with Miller Class I and II gingival recession (GR) abnormalities using platelet-rich fibrin (PRF) membrane with coronal advanced flaps (CAFs) with and without vertical releasing incisions (VRIs; the envelope-type flap and the flap with VRIs). MATERIALS AND METHODS Seven defects from each of the test and control groups made up of fourteen defects total. In the test group, PRF + CAF was performed without VRI, while in the control group, VRI was used. Gain in root coverage was the main result, with secondary results including papillary bleeding index (PBI), plaque index (PI), relative gingival margin level, relative attachment level, probing pocket depth, recession depth, width of keratinized gingiva (WKG), and gingival thickness. After 3 months of therapy, a clinical evaluation was conducted. RESULTS No significant difference was observed between the two groups in terms of recession reduction (2.08 ± 0.5 vs 1.91 ± 0.66 mm), clinical attachment level (CAL) gain (2.08 ± 0.5 vs 1.91 ± 0.66 mm), and increase in WKG (2.66 ± 0.88 vs 2.58 ± 0.51 mm) for test and control groups, respectively. CONCLUSION For the treatment of GR, both groups are efficient. However, the CAF + PRF without VRI group showed higher patient compliance and lower postoperative morbidity. CLINICAL RELEVANCE The PRF membrane with CAF with or without VRI provide effective treatment option for GR. CAF + PRF without VRI is easy to perform and has less postoperative complications.

Abstract
OBJECTIVES To compare the percentage of mean root coverage (MRC%) obtained in the treatment of multiple Miller class III/RT2 gingival recessions using the modified VISTA (m-VISTA) technique versus the coronally advanced flap (CAF) technique, using a connective tissue graft (CTG) in both cases. MATERIALS AND METHODS Twenty-four patients were randomly treated with m-VISTA (test group (TG) = 12) or CAF (control group (CG) = 12). A calibrated, experienced, and blinded examiner collected data related to multiple periodontal clinical variables, especially the recession (REC) in order to calculate the MRC% at 6 and 12 months, which was the primary outcome of the study. Also, the radiological bone level, the characteristics of the CTG, and postsurgical incidences were assessed. Finally, a descriptive and an analytical statistical analysis of the variables and their associations was performed. RESULTS The recessions (n = 84) were located mainly in the mandible (n = 65) and in posterior sectors (premolars: n = 35; molars: n = 8). At 6 months, the MRC% was 61% (2 mm) for both study groups, and at 12 months, it increased to 73.26% (2.11 mm) in the TG and decreased to 56.49% (1.78 mm) in the CG. CONCLUSION When approaching multiple Miller class III/RT2 recessions, there were no statistically significant differences in the MRC% at 6 and 12 months between the group treated with the m-VISTA technique and the group treated with the CAF. CLINICAL RELEVANCE The characteristics of the m-VISTA technique, such as the closed approach, the mobilization of the papilla, and the coronal stabilization of the CTG, could facilitate the maturation of the tissues in the treatment of Miller class III/RT2 recessions. This would favor better root coverage. TRIAL REGISTRATION NCT03258996.

Efficacy of biologics in root coverage and gingival augmentation therapy: An American Academy of Periodontology best evidence systematic review and network meta-analysis. J Periodontol 2022; 93:1771-1802. [PMID: 36279123 DOI: 10.1002/jper.22-0075] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Revised: 04/05/2022] [Accepted: 04/06/2022] [Indexed: 01/05/2023]
Abstract
BACKGROUND The aim of this systematic review was to assess the efficacy of three biologics, namely autologous blood-derived products (ABPs), enamel matrix derivatives (EMD) and recombinant human platelet-derived growth factor BB (rhPDGF-BB), in root coverage and gingival augmentation therapy. METHODS The protocol of this PRISMA 2020-compliant systematic review was registered in PROSPERO (CRD42021285917). After study selection, data of interest were extracted. A network meta-analysis (NMA) was conducted to assess the effect of different surgical interventions on the main clinical outcomes of interest (i.e., mean root coverage [MRC%], complete root coverage [CRC%], keratinized tissue width [KTW], gingival thickness [GT] change, and recession depth [RD] reduction). RESULTS A total of 48 trials reported in 55 articles were selected. All studies reported on the treatment of gingival recession defects for root coverage purposes. Forty-six treatment arms from 24 trials were included in the NMA. These arms consisted of treatment with coronally advanced flap (CAF) alone, EMD + CAF, platelet-rich fibrin (PRF) + CAF, and subepithelial connective tissue graft (SCTG) + CAF. Regarding MRC%, SCTG+CAF was associated with a significant higher estimate (13.41%, 95% CI [8.06-18.75], P < 0.01), while EMD+CAF (6.68%, 95% CI [-0.03 to 13.4], P = 0.061) and PRF+CAF (1.03%, 95% CI [-5.65 to 7.72], P = 0.71) failed to show statistically significant differences compared with CAF alone (control group) or with each other. Similarly, only SCTG+CAF led to a significantly higher CRC% (14.41%, 95% CI [4.21 to 24.61], P < 0.01), while treatment arms EMD + CAF (13.48%, 95% CI [-3.34 to 30.32], P = 0.11) and PRF+CAF (-0.91%, 95% CI [-15.38, 13.57], p = 0.81) did not show significant differences compared with CAF alone or with each other. Differences in the CI of PRF+CAF (symmetrical around a zero adjunctive effect) and EMD+CAF (non-symmetrical) suggest that EMD could have some additional value compared with PRF. Treatment with SCTG+CAF led to a statistically significant higher RD reduction (-0.39 mm, 95% CI [-0.55 to 0.22], P < 0.01), however EMD+CAF (-0.13 mm, 95% CI [-0.29 to 0.01], P = 0.08) and PRF+CAF (-0.06 mm, 95% CI [-0.23 to 0.09], P = 0.39) failed to show significant differences compared with CAF or with each other. While SCTG+CAF was associated with a statistically significant higher gain of KTW (0.71 mm, 95% CI [0.48 to 0.93], P < 0.01), EMD+CAF (0.24 mm, 95% CI [-0.02 to 0.51], P = 0.08) and PRF+CAF (0.08 mm, 95% CI [-0.23 to 0.41], P = 0.58) did not result into significant changes compared with CAF alone or with each other. Regarding the use of rhPDGF-BB+CAF, although available studies have reported equivalent results compared with SCTG+CAF, evidence is very limited. CONCLUSIONS The use of ABPs, EMD, or rhPDGF-BB in conjunction with a CAF for root coverage purposes is safe and generally promotes significant improvements respective to baseline clinical parameters. However, the adjunctive use of ABPs and EMD does not provide substantial additional improvements in terms of clinical outcomes and patient-reported outcome measures to those achieved using CAF alone, when baseline KTW is >2 mm. Both PRF+CAF and EMD+CAF rendered inferior MRC%, CRC%, RD reduction, and KTW gain compared with SCTG+CAF, which should still be considered the gold-standard in root coverage therapy. Although some studies have reported equivalent results for rhPDGF-BB+CAF compared with the gold-standard intervention, limited evidence precludes formal comparisons with CAF or SCTG+CAF that could be extrapolated to guide clinical practice.

Abstract
BACKGROUND Mucogingival deformities are prevalent oral conditions and can result in esthetic compromise, dentinal hypersensitivity, and an increase in radicular caries rates. Mucogingival treatments address thin periodontal phenotype and/or gingival recession defects. Although many of these grafting procedures are predictable in improving soft-tissue quality and quantity around teeth and dental implants, patients often complain of discomfort at both the donor and recipient sites. Free gingival grafts and coronally advanced flaps alone or in combination with subepithelial connective tissue graft and/or acellular dermal matrix are among the most common surgical procedures employed to achieve root coverage and enhance periodontal phenotype. Autologous blood products (ABPs) contain platelets, growth factors, leukocytes, and stem cells that contribute to cell mitosis, collagen production, and angiogenesis, leading to the healing and regeneration of hard and soft tissue. Evaluation of the adjunctive role of ABPs in mucogingival surgery and their impacts on clinical and patient-centered data is critical to achieve optimal patient-reported outcome measures based upon the current scientific evidence. METHODS We present exemplar cases in which adjunctive ABPs were utilized in mucogingival treatment to enhance treatment outcomes. RESULTS No adverse events were noted. Satisfactory treatment outcomes were achieved in patients with local and/or systemic compromise when mucogingival therapies were used in combination with ABPs. CONCLUSIONS Adjunctive use of ABPs may enhance outcomes of mucogingival therapy. Utilization of adjunctive ABPs may be particularly advantageous in situations where the predictability of clinical and esthetic outcomes is limited due to anatomical and/or patient factors.

Abstract
BACKGROUND Dentofacial esthetics has become a mainstay treatment in periodontics. For a periodontal private practice to succeed in a referral-based environment, predictability and stability in treatment results are crucial. The scientific literature provides a guide to successfully treating multiple recession defects with non-carious cervical lesions and lingual recession. These case reports show how the use of biologic mediators, proper case selection, and proper surgical technique may provide a better treatment outcome for our patients. METHODS Two patients with multiple gingival recession defects were treated with autogenous tissue grafting in conjunction with the application of enamel matrix derivative (EMD) to attempt root coverage. Based on the Cairo classification, the recession defects were classified as type I in the maxillary buccal and lingual recession in the mandibular anterior. There were areas of no attached gingiva, loss of enamel, and the presence of non-carious cervical lesions. RESULTS At 3-month post-treatment in case #1 and 6-month post-treatment in case #2, satisfactory esthetic results for the patients and clinician were achieved. These short-term follow-ups were favorable for root coverage and soft tissue healing, especially at the 1-week visit. There was noticeably less edema and erythema. Additionally, dental hypersensitivity was no longer reported for both patients. CONCLUSION By using biologic mediators, such as an EMD combined with connective tissue grafting, both multiple recession defects with non-carious cervical lesions, and lingual recession cases, can be treated successfully in a private practice setting. Using an EMD provides no additional risks to patients, may result in faster healing, and would afford stability of long-term success by influencing true periodontal regeneration.

Abstract
BACKGROUND The purpose of this study was to investigate the influence of vestibular depth (VD) on the outcomes of root coverage therapy. METHODS Patients presenting gingival recession defects (GRD) with a minimum depth of 2 mm underwent root coverage therapy consisting of a coronally advanced flap plus a connective tissue graft (CAF + CTG). Clinical examinations were performed, and intraoral scans were obtained at baseline, 3 and 6 months after surgery to assess changes in probing depth (PD), keratinized tissue width (KTW), recession depth (RD), GRD area, marginal gingival thickness (MGT), and VD. The influence of VD on percentage of root coverage (%RC) and the likelihood of achieving complete root coverage (CRC) were explored. RESULTS A total of 20 patients were enrolled, and 44 teeth were treated. RD decreased and MGT increased in all treated sites. At 6 months, mean %RC was 87.47 ± 18.37 and CRC was observed in 61.4% of sites. Mean baseline VD was 7.33 ± 2.67 mm. Mean VD reduction from baseline to 6 months was 1.98 ± 1.27 mm. %RC and CRC were significantly correlated with baseline VD. Each additional 1 mm of baseline VD implied a gain of 6.58% for %RC and increased 2.75 times the probability of achieving CRC. Narrow baseline KTW and mandibular arch location were associated with inferior treatment outcomes. CONCLUSION Lower %RC and likelihood of achieving CRC can be expected after root coverage therapy via CAF + CTG in sites presenting a shallow vestibulum.

[PMID: 36143324 PMCID: PMC9501956 DOI: 10.3390/jpm12091539] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2022] [Revised: 09/06/2022] [Accepted: 09/16/2022] [Indexed: 11/21/2022] Open
Abstract
Previous systematic reviews have reported that coronally advanced flap (CAF) + connective tissue graft (CTG) are the gold standard in root coverage procedures (RCP). Nevertheless, adjunctive treatment with hyaluronic acid (HA) has been proposed to aim at improving clinical outcomes and reducing patient morbidity. The aim of this systematic review and meta-analysis is to compare the use of HA as an adjunctive treatment to CAF procedures in Miller class I and II (recession type 1; RT1) gingival recession (GR) defects treatment with no adjunctive/other treatments. MEDLINE, The Cochrane Central Register of Controlled Trials, Web of Science, Scopus databases and gray literature were searched up to April 2022. The primary outcome variables were mean recession coverage (MRC) and reduction of the recession depth (RecRed). Weighted mean differences and 95% confidence intervals between treatments were estimated using a random-effect mode. From 264 titles identified, 3 RCTs reporting 90 GR defects in 60 patients were included. Overall analysis of MRC and RecRed were 0.27% (p = 0.01) and 0.40 mm (p = 0.45) in favor of CAF + HA compared to CAF alone/CAF + subepithelial connective tissue graft (SCTG), respectively, with a statistically significant difference only for MRC values. Nevertheless, due to the limited number and heterogeneity of the included studies, well-performed RCTs are needed to clarify a potential advantage of HA in RCPs in the future.

Seidel A, Schmitt C, Matta RE, Buchbender M, Wichmann M, Berger L. Investigation of the palatal soft tissue volume: a 3D virtual analysis for digital workflows and presurgical planning. BMC Oral Health 2022; 22:361. [PMID: 35999531 PMCID: PMC9400256 DOI: 10.1186/s12903-022-02391-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 08/11/2022] [Indexed: 12/04/2022] Open
Abstract
Background In mucogingival and implant surgery, an autologous soft tissue graft from the palate is the gold standard for reconstructing missing keratinised soft tissue and volume. Previously, presurgical measurements of the graft harvesting site were described with two-dimensional (2D) linear measurements. The present observational clinical study aimed to evaluate a three-dimensional (3D) measurement method for determining the present palatal soft tissue volume for each patient individually. Methods Pre-existing cone beam computed tomography (CBCT) scans of 20 patients were converted into 3D Standard Tessellation Language models of the bone surface. Intraoral impressions of the maxilla were taken and digitised to visualise the gingival surface. The resulting virtual models of bone (reference value) and gingival (actual value) surfaces were merged, with tooth surfaces used for registration. The region between the central incisors and the hard palate was subdivided into 5 regions of interest (ROIs). The distance between palatal bone and gingival surface was analysed both volumetrically and linearly, and the results were statistically evaluated for the ROIs.
Results The average gingival surface area on the palate was 19.1 cm2, and the mean volume was 58.2 cm3 (± 16.89). Among the ROIs, the mean linear value was highest in the most distal region, from the second molar to the hard palate (4.0 ± 1.09 mm) and lowest in the canine region (1.9 ± 0.63 mm). For mean distance, significant differences were found for the anterior palate and the most posterior palate in comparison with all other ROIs (p < 0.01). The volume measurements also declined significantly and steadily between the posterior (1.9 ± 1.0 cm3) and anterior palates (0.4 ± 0.2 cm3). Conclusions By merging digital data, palatal soft tissue could be quantified virtually. The results were reliable and comparable to previous findings with linear measurement methods. This 3D soft tissue volume analysis method fully exploited the diagnostic potential of data that are frequently collected for presurgical planning in oral surgery (i.e., CBCT + surface scans). This evaluation method might be useful for volumetric and linear measurements in other applications in anatomy and for determining palatal soft tissue dimensions in the planning stage before surgical interventions. Trial registration This observational clinical trial was retrospectively registered in the German Clinical Trials Register, reference number: DRKS00023918.
