Abstract
OBJECTIVE The purpose of this study was to assess the feasibility of phenotype modification in orthodontic patients using combined bone and soft tissue grafting substitutes. CLINICAL CONSIDERATION The surgical procedure was conducted on 18 patients (3 males, 15 females). Periodontal phenotype modification was conducted using demineralized freeze-dried bone allograft and a xenogeneic collagen matrix. The following parameters were recorded for each tooth at baseline and 12-month follow-up: O'Leary plaque index (PI), probing depth (PD), bleeding on probing (BOP), gingival thickness (GT), keratinized tissue width (KTW), gingival recession (GR), and vestibular depth (VD). The results showed a statistically significant increase in GT (2.02 ± 0.39 mm), KTW (1.11 ± 0.82 mm), and VD (0.18 ± 1.16 mm) (p < 0.05). GR was also significantly decreased (1.02 ± 0.99 mm) (p < 0.05). CONCLUSION Within the limitation of this study, the proposed approach enhanced the periodontal condition in orthodontic patients. However, further studies with a larger sample size are needed to ensure long-term stability. CLINICAL SIGNIFICANCE Hard and soft tissue conditions have paramount importance for long-term periodontal stability. Phenotype modification in orthodontic patients can diminish the probability of adverse consequences and result in optimal esthetic outcomes. The proposed technique using combined bone and soft tissue substitutes indicated promising results and could be recommended in orthodontic patients with thin periodontal phenotypes.

Abstract
Class IV dental diode lasers have been introduced as a nonsurgical therapy for periodontal pockets in veterinary and human dentistry. This retrospective case series evaluates the use of Class IV dental diode laser therapy for abnormal periodontal pockets in a specialty veterinary dental practice. A hypothesis that the Class IV diode dental laser is a useful adjuvant modality in canine periodontal pocket therapy in the reduction of clinical pocket depth was made. This article discusses and demonstrates diode laser use in periodontal pocket therapy in a specialty veterinary dental practice and reviews the current literature. Inclusion in this study was limited to client-owned dogs with noted periodontal pocketing on any tooth type between 3 and 6 mm, which were treated with closed root planing (RP/C) and laser therapy who returned in 6 to 7 months for recheck of the pockets from the years 2017 to 2020. Twelve patients met the inclusion criteria. A total of 128 periodontal pockets were included in the study. Each periodontal pocket was a case receiving therapy. The mean periodontal pocket depth before the treatment is measured as 3.35 mm. The mean pocket depth of the periodontal pockets following treatment was 0.59 mm. The mean improvement in periodontal pocket depths after diode laser therapy when considering patient and tooth number using linear mixed-effects modeling was 2.63 mm (95% confidence interval [CI]: 1.81-3.46, P < .0001). No statistically significant results were observed for pocket type, as P values were greater than .05.

Abstract
PURPOSE To investigate the effect of endoscopy-aided non-incisional periodontal regeneration technique (NIT) in the treatment of alveolar bone angular resorption. METHODS Thirteen patients with severe periodontitis(13 diseased teeth) were selected. All patients had alveolar bone angular resorption on adjacent surface. The patients received NIT treatment 6 weeks after periodontal primary therapy. The visualization of subgingival environment was acquired by the periodontal endoscopy. Following the removal of the subgingival plaque, calculus and intra-bony granulation tissue, bone grafting materials were placed into the intra-bony defects with the assistance of a delicate gingival protector. No flap was elevated and no sutures were applied. Probing depth (PD), gingival recession (GR), clinical attachment level (CAL), as well as radiographic parameters were evaluated at baseline and 2 years after treatment. SPSS 22.0 software package was used for data analysis. RESULTS At 2-years follow-up, an average CAL gain of (3.65±2.10) mm (P<0.001), PD reduction of (4.42±1.66) mm (P<0.001), and minimal increase in GR of (0.38±0.87) mm (P=0.25) were observed. Alveolar bone was significantly improved at 2-years follow-up on radiographs (P<0.001). CONCLUSIONS For angular resorption site of alveolar bone, NIT treatment can obtain good periodontal regeneration results without flap inversion.

Abstract
OBJECTIVES This study assessed the effectiveness of prehydrated collagenated xenogenic bone gel and a collagenated cortico-cancellous heterologous bone mixture in conjunction with papillae tunneling techniques (PTT) for treating isolated periodontal intraosseous defects. MATERIALS AND METHODS Twenty patients with periodontitis stage III/IV and at least one deep isolated interdental 2/3-wall intraosseous defect were included in the study. Surgical incisions were made vertically at the adjacent tooth or horizontally at the mucogingival junction. A full-thickness flap was then carefully lifted under the papillae using special tunneling instruments. The root surfaces were completely cleaned, and the defects were randomly filled with either prehydrated collagenated bone gel (test group; n = 10) or collagenated cortico-cancellous heterologous bone mixture (control group; n = 10). Wounds were closed with microsurgical sutures. We predicted that the lower 95% confidence interval for the difference between the two procedures would exceed a prespecified noninferiority threshold. RESULTS All wounds closed sufficiently to prevent biomaterial exposure. The test and control groups showed similar mean pocket depth reduction (3.5 ± 1.0 vs. 3.9 ± 1.7 mm; p = 0.52), similar gingival recession (-0.10 ± 0.99 vs. 0.2 ± 0.8 mm; p = 0.46), and similar clinical attachment gain (3.6 ± 1.51 vs. 3.7 ± 1.8 mm; p = 0.89) at the 12-month follow-up. All results were below the noninferiority margin of the sample. CONCLUSIONS At 12 months, prehydrated collagenous bone gel performed similarly to collagenous heterologous bone granules in the treatment of intraosseous lesions with PTT. In addition, both biomaterials preserved soft tissue with minimal further recession at 1 year. CLINICAL RELEVANCE When combined with PTT, collagenous xenogeneic bone granules and prehydrated collagenous bone gel achieve comparable clinical outcomes in intrabony defects. The study was registered under the NCT04782921 on ClinicalTrails.

Abstract
The purpose of the present study was to describe a novel protocol for a minimally invasive pocket elimination surgery (MI-PES) in the posterior maxilla and mandible, which consists of the combined use of (1) an access flap based on an internally beveled gingivectomy with minimal to no papilla mobilization at the buccal aspect, and (2) a resective procedure with an apically positioned flap on the lingual aspect. The interproximal bone defects were accessed with a single (lingual) flap, and the bone architecture was modified by the adoption of piezoelectric inserts for controlled bone recontouring associated with fiber retention. Mean probing depth (PD) was 5.5 ± 0.8 mm before surgery and 2.7 ± 0.6 mm at the 6-month reevaluation. All treated pockets showed a postsurgical PD < 4 mm. Gingival recession (REC) was 0.3 ± 0.5 mm at baseline and increased to 1.6 ± 0.8 mm at 6 months. When buccal and lingual pockets were analyzed separately, a trend toward a similar PD reduction, less REC increase, and greater clinical attachment level gain was recorded for buccal pockets. These preliminary observations seem to support the use of MI-PES as a valuable option for pocket elimination, at least when residual pockets are associated with a shallow interproximal osseous crater in the posterior maxilla or mandible.

Abstract
BACKGROUND Gingival recession and post-operation discomfort are still a problem for patients receiving the periodontal regeneration surgery for intra-bony defects. To further reduce the trauma and the post-operation gingival recession, a novel periodontal endoscopy-aided non-incisional regeneration technique (NIT) was proposed in the treatment of intra-bony defects. METHODS Retrospective analysis of 21 subjects treated with NIT and 21 subjects with periodontal endoscopy-aided scaling and root planing (PSRP) at baseline and 1-year evaluation was conducted. After removing the subgingival calculus and granulation tissue, bone grafting materials were placed into intrabony defects with the assistance of a gingival retractor in the NIT group. Probing depth (PD), gingival recession (GR), clinical attachment level (CAL), as well as the distance between bone crest (BC) level and base of the defect (BD) (intrabony defect depth, IBD) were evaluated at baseline and 1 year after treatment. RESULTS At 1-year follow-up, the value of CAL, PD and IBD were statistically significant different compared with baseline in both two groups (p<0.001). CAL gain (p = 0.012) and PD reduction (p = 0.004) was greater in the NIT than PSRP. However, no difference in the IBD reduction was found between the NIT group and PSRP. Better CAL gain and PD reduction was achieved in the 1-year term in the NIT when compared with PSRP. CONCLUSION NIT have resulted in significant gains in both clinical and radiographic parameters. NIT might be utilized as an alternative of the surgical treatment for periodontal intrabony defects. TRIAL REGISTRATION This clinical trial registration was registered retrospectively (August 3, 2023) and the number is ChiCTR2300074317.

Abstract
OBJECTIVE The objective of the present study was to evaluate the clinical and radiographic outcomes of intrabony defects treated with decortication (intramarrow penetration) alone versus decortication combined with platelet-rich fibrin in periodontitis patients followed up for 6 months postsurgery. METHOD AND MATERIALS A total of 46 intrabony defects from periodontitis patients with a mean age of 36.30 ± 6.10 years were randomly assigned into two treatment groups. The control group (n = 23) intrabony sites were accessed with simplified papilla preservation flap (SPPF) followed with debridement, decortication, and closure. The test group (n = 23) sites were accessed with SPPF, followed with debridement, decortication, platelet-rich fibrin placement, and closure. The clinical parameters Plaque Index, Gingival Index, probing pocket depth, relative attachment level, gingival marginal level, along with radiographic defect depth and defect width were recorded at baseline, 3 months, and 6 months postsurgery. Gain in clinical attachment level was the primary outcome, and probing pocket depth reduction and radiographic bone fill were secondary outcomes of the study. RESULTS The Plaque Index and Gingival Index scores showed nonsignificant difference on intra- and intergroup comparison at baseline, 3 months, and 6 months. The probing pocket depth was 8.17 ± 1.56 mm, 6.65 ± 1.30 mm, and 5.26 ± 1.18 mm for the control group, and 8.17 ± 2.01 mm, 6.26 ± 1.42 mm, and 4.78 ± 1.28 mm for the test group, at baseline, 3 months, and 6 months, respectively. The relative attachment level was 8.83 ± 1.40 mm, 6.78 ± 1.31 mm, and 5.39 ± 1.16 mm for the control group, and 8.39 ± 1.62 mm, 6.96 ± 1.36 mm, and 5.48 ± 1.20 mm for the test group at baseline, 3 months, and 6 months, respectively. Statistically significant reductions were observed for probing pocket depth for the control (2.91 mm, P < .001) and test groups (3.39 mm, P < .001), as well as for relative attachment level for the control (3.44 mm, P < .001) and test groups (2.91 mm, P < .001). However, intergroup differences were nonsignificant for probing pocket depth and relative attachment level. The radiographic defect depth was reduced by 0.31 mm for the control and 1.57 mm for the test group. The radiographic defect width was reduced by 0.18 mm for the control and 0.83 mm for the test group. Intergroup statistically significant differences were observed at the 6-month follow-up (P < .001) for radiographic defect depth and width. CONCLUSION Within the limitations of the present study, the results demonstrate statistically significant intragroup improvements in clinical outcomes with decortication alone and decortication combined with platelet-rich fibrin in the treatment of intrabony defects in periodontitis patients. The addition of platelet-rich fibrin did not improve the clinical results beyond decortication alone, and unacceptable postsurgery residual pockets were observed in both the protocols. Considering the small sample size, the addition of platelet-rich fibrin resulted in significant bone fill over and above that of decortication alone.

Abstract
BACKGROUND This study aimed to evaluate the long-term effectiveness of regenerative treatment of intra-bony defects in combination with consecutive orthodontic therapy (OT) in stage IV periodontitis. METHODS Twenty-two patients with a total of 256 intra-bony defects were analyzed after regenerative surgery followed by OT initiated 3 months later. Changes in radiographic bone level (rBL) and probing pocket depths (PPD) were evaluated after 1 year (T1), final splinting (T2), and 10 years (T10). RESULTS Mean rBL gain was significant with 4.63 mm (±2.43 mm) after 1 year (T1), 4.19 mm (±2.61 mm) at final splinting (T2), and 4.48 mm (±2.62 mm) after 10 years (T10). Mean PPD was significantly reduced from 5.84 mm (±2.05 mm) at baseline to 3.19 mm (±1.23 mm) at T1, to 3.07 mm (±1.23 mm) at T2, and to 2.93 mm (±1.24 mm) at T10. Pocket closure (PPD ≤ 4 mm) was achieved in 90% of all defects. Tooth loss amounted to 4.5%. CONCLUSIONS Within the limitations of this retrospective study design, these 10-year findings suggest that in motivated and compliant patients with stage IV periodontitis and in need of OT an inter-disciplinary treatment can lead to favorable and stable long-term results.

Abstract
BACKGROUND This study evaluated the effectiveness of a novel pocket therapy (Er:YAG laser-assisted comprehensive periodontal pocket therapy [Er-LCPT]) for residual pocket treatment, compared with conventional mechanical treatment alone, in a randomized controlled clinical trial. METHODS Two sites in 18 patients having residual periodontal pockets of ≥5 mm depth, extant following initial active therapy, or during supportive therapy, were randomized into two groups in a split mouth design: the control group received scaling and root planing (SRP) by curette, and the test group received Er-LCPT using curette and laser. With Er-LCPT, after root debridement, inflamed connective tissue on the inner gingival surface and on the bone surface/within extant bone defects was thoroughly debrided. Furthermore, removal of proximate oral epithelium and coagulation of the blood clot in the pocket entrance were performed with laser. Clinical parameters were evaluated, before and after treatment, through 12 months. RESULTS Both groups showed significant improvements in clinical parameters. With Er-LCPT, pocket debridement was thoroughly and safely performed, without any adverse side effects and complications, and favorable healing was observed in most of the cases. At 12 months, Er-LCPT demonstrated significantly higher probing pocket depth reduction (2.78 mm vs. 1.89 mm on average; p = 0.012, Wilcoxon signed-rank test), clinical attachment gain (1.67 mm vs. 1.06 mm; p = 0.004) as primary outcomes, and reduced BOP value (0.89 vs. 0.56; p = 0.031), compared with SRP alone. CONCLUSION The results of this study indicate that Er-LCPT is more effective for residual pocket treatment, compared with SRP alone.

Abstract
BACKGROUND Recently, a composite outcome measure (COM) was proposed to describe the short-term results of periodontal regenerative treatment. The present retrospective study aimed at evaluating the prognostic value of COM on clinical attachment level (CAL) change over a 4-year period of supportive periodontal care (SPC). METHODS Seventy-four intraosseous defects in 59 patients were evaluated at 6 months and 4 years following regenerative treatment. Based on 6-month CAL change and probing depth (PD), defects were classified as: COM1 (CAL gain ≥3 mm, PD ≤4 mm); COM2 (CAL gain <3 mm, PD ≤4 mm); COM3 (CAL gain ≥3 mm, PD >4 mm); or COM4 (CAL gain <3 mm, PD >4 mm). COM groups were compared for "stability" (i.e., CAL gain, no change in CAL or CAL loss <1 mm) at 4 years. Also, groups were compared for mean change in PD and CAL, need for surgical retreatment, and tooth survival. RESULTS At 4 years, the proportion of stable defects in COM1, COM2, COM3, and COM4 group was 69.2%, 75%, 50%, and 28.6%, respectively, with a substantially higher probability for a defect to show stability for COM1, COM2, and COM3 compared with COM4 (odds ratio 4.6, 9.1, and 2.4, respectively). Although higher prevalence of surgical reinterventions and lower tooth survival were observed in COM4, no significant differences were detected among COM groups. CONCLUSIONS COM may be of value in predicting CAL change at sites undergoing SPC following periodontal regenerative surgery. Studies on larger cohorts, however, are needed to substantiate the present findings.

Abstract
AIM To assess the long-term stability of attachment gain in infrabony defects (IBDs) 10 years after regenerative treatment with an enamel matrix derivative (EMD) alone. MATERIALS AND METHODS Two centres (Frankfurt [F] and Heidelberg [HD]) invited patients for re-examination 120 ± 12 months after regenerative therapy. Re-examination included clinical examination (periodontal probing depths (PPD), vertical clinical attachment level (CAL), plaque index (PlI), gingival index (GI), plaque control record, gingival bleeding index and periodontal risk assessment) and review of patient charts (number of supportive periodontal care [SPC] visits). RESULTS Both centres included 52 patients (29 female; median baseline age: 52.0 years; lower/upper quartile: 45.0/58.8 years; eight smokers), each contributing one IBD. Nine teeth were lost. For the remaining 43 teeth, regenerative therapy showed significant CAL gain after 1 year (3.0; 2.0/4.4 mm; p < .001) and 10 years (3.0; 1.5/4.1 mm; p < .001) during which CAL remained stable (-0.5; -1.0/1.0 mm; p = 1.000) after an average SPC of 9 years. Mixed-model regression analyses revealed a positive association of CAL gain from 1 to 10 years with CAL 12 months post operation (logistic: p = .01) as well as a higher probability for CAL loss with an increasing vertical extent of a three-walled defect component (linear: p = .008). Cox proportional hazard analysis showed a positive association between PlI after 12 months and tooth loss (p = .046). CONCLUSION Regenerative therapy of IBDs showed stable results over 9 years. CAL gain is associated with CAL after 12 months and decreasing initial defect depth in a three-walled defect morphology. Tooth loss is associated with PlI 12 months post operation.

Abstract
OBJECTIVES The color is a major factor in determining inflammation status in most gingival indices. Current indices have limitations mainly due to subjective nature. Digital color analysis can provide objective and accurate measurements. Thus, the present study aimed to assess by digital tool the gingival color in the different stages of an active periodontal treatment. METHODS Forty patients (19 males and 21 females) diagnosed with periodontitis (stage III/ IV, grade C) and treated surgically were included in the study. Clinical data (probing depth, bleeding on probing, clinical attachment level, gingival index, and gingival recession) and photographs by digital single-lens-reflex (DSLR) camera were recorded before initial periodontal treatment, which included scaling and root surface debridement (T0); the same parameters were then re-evaluated 6-8 weeks (T1) and 3 months after periodontal surgery (regenerative/resective) (T2). Differences between clinical parameters were calculated. The color space defined by the International Commission on Illumination (CIELab) was used to analyze gingival color. RESULTS In 56 periodontal surgical sites, 168 photographs were taken. The a*-value of the CIELab color system (higher a*- value translate to a stronger red color) was significantly reduced between T0 to T1 and further decreased at T2 (32.01, 29.28, and 27.45 respectively). Significant improvement in clinical parameters were found between T0 to T1 and T1 to T2. Sub-analysis of two distinct surgical interventions revealed that only regenerative procedure improved the a*-value, which was significantly correlated with pocket depth reduction. CONCLUSIONS Photometric analysis can be used to assess gingival color change during periodontal treatment of patients with periodontitis. CLINICAL SIGNIFICANCE Gingival inflammation is a major factor in periodontal assessment; nevertheless, all current gingival inflammation indices are partially subjective and only semi-quantitative. The digital photometric analysis may allow for accurate and objective gingival color assessment during periodontal treatment.

Abstract
The outcome in the treatment of furcation defects is often unsatisfactory. The reasons are morphologic and pathologic peculiarities as well as extensive changes in shape caused by resective treatment of periodontal lesions in multi-rooted teeth. Therefore, augmentative strategies are suggested to improve the prognosis. However, the success rate decreases with increasing severity of the disease. In contrast, if the affected roots are not extracted but are extruded after hemi- or trisection, this leads to a coronal displacement of the disease process and a significantly improved situation for hygiene. At the same time, the resection of inflammatory tissue of the periodontal pockets is accompanied by vertical and horizontal bone apposition. The results are predictable and stable in the long term. The burden for the patient is low. ((Quintessence Int 2022;53: 884-891; Originally published (in German) in Quintessenz Zahnmedizin 2020; 71(9): 1024-1032; doi: 10.3290/j.qi.b3418205).

Abstract
OBJECTIVE To evaluate the five-year results following regenerative periodontal surgery of intrabony defects using an enamel matrix derivative (EMD) in patients with different smoking status. METHOD AND MATERIALS The dental records of patients treated with regenerative periodontal surgery with EMD between 2001 and 2011 were screened. The clinical parameters at baseline (T0) and 6 months (T1) and 5 years (T2) after surgery were collected and analyzed in relation to patient's smoking status (smokers, former smokers, and nonsmokers). RESULTS A total of 71 sites were initially assessed in 38 patients. In total, 56 sites could be evaluated at T1, and 34 after 5 years (T2). At 6 months after surgery, a statistically significant mean probing pocket depth (PPD) reduction of 2.91 ± 1.60 mm and a mean clinical attachment level (CAL) gain of 1.89 ± 1.90 mm were measured. Nonsmokers revealed a greater, statistically not significant CAL gain compared to smokers (2.38 ± 2.12 mm vs 1.50 ± 1.71 mm). Although at 5 years the site-specific PPD values remained stable in nonsmokers, smokers showed an increase of 1.60 ± 2.41 mm. CONCLUSIONS The present study provides evidence that regenerative periodontal surgery with EMD may lead to clinically relevant improvements even in smoking patients. However, the positive effect of EMD seems to be limited in time and can only partially compensate for the negative influence of smoking.

Abstract
Background Periodontitis is the common oral condition which affects the periodontium of the teeth that leads to destruction of periodontal ligaments and alveolar bone. Open flap debridement is the surgical procedure which provides access and visibility of the site, application of laser as an adjunct has various advantanges. Objective To compare clinical outcomes after open flap debridement with or without diode laser. Method Patients aged 25-45 years diagnosed with infrabony defect ≥ 5 mm visiting Department of Dental Surgery, Bir Hospital. Control group sites were treated with open flap debridement alone, whereas test-groups were treated with Open flap debridement with diode laser. Various parameters like Plaque index, Gingival index, Pocket depth and Clinical attachment level were assessed and compared between groups at baseline, 3 and 6 months. Result The mean plaque and gingival scores improved in both the control and test groups at 3 and 6 months follow up as compared to baseline and was statistically nonsignificant between two groups. Open flap debridement with or without diode laser in the treatment of periodontal intrabony defects did not produce significant reduction in pocket depth and gain in clinical attachment level. Conclusion There was no significant differences in the clinical parameters were seen in the surgical flap debridement of infrabony pocket with and without diode laser. Diode laser can be used safely as an adjunct. However, long-term, multicentric, histologic and microbial studies are required.

Abstract
OBJECTIVE The aim of the current article was to present a radiographic method to determine the surface area of newly formed periodontal attachment, as well as to analyze volumetric and morphologic changes after regenerative periodontal treatment. METHOD AND MATERIALS In this retrospective study, 11 singular intrabony periodontal defects were selected for minimally invasive surgical treatment and 3D evaluation. 3D virtual models were acquired by the segmentation of pre- and postoperative CBCT scans. This study determined the surface area of baseline periodontal attachment (RSA-A) and defect-involved root surface (RSA-D) on the preoperative 3D models, and the surface area of new periodontal attachment (RSA-NA) on the postoperative models. Finally, cumulative change of periodontal attachment (∆RSA-A) was calculated and Boolean subtraction was applied on pre- and postoperative 3D models to demonstrate postoperative 3D hard tissue alterations. RESULTS The average RSA-A was 84.39 ± 33.27 mm2, while the average RSA-D was 24.26 ± 11.94 mm2. The average surface area of RSA-NA after regenerative periodontal surgery was 17.68 ± 10.56 mm2. Additionally, ∆RSA-A was determined to assess the overall effects of ridge alterations on periodontal attachment, averaging 15.53 ± 12.47 mm2, which was found to be statistically significant (P = .00149). Lastly, the volumetric hard tissue gain was found to be 33.56 ± 19.35 mm3, whereas hard tissue resorption of 26.31 ± 38.39 mm3 occurred. CONCLUSION The proposed 3D radiographic method provides a detailed understanding of new periodontal attachment formation and hard tissue alterations following regenerative surgical treatment of intrabony periodontal defects.

Abstract
OBJECTIVES The minimally invasive surgical technique was modified in suture (MISTms) in this study. The trial was to determine the efficacy of MISTms with and without regenerative materials for the treatment of intrabony defect and to identify factors influencing 1-year clinical attachment level (CAL) gain. METHODS Thirty-six patients with interdental intrabony defects were randomly assigned to MISTms (MISTms alone, 18) or MISTms plus deproteinized bovine bone mineral and collagen membrane (MISTms combined, 18). Wound healing was evaluated by early healing index (EHI) at 1, 2, 3, and 6 weeks. Probing depth (PD), CAL, gingival recession, radiographic defect depth, and distance from the base of defect to the cementoenamel junction were recorded at baseline and 1 year postoperatively. A one-year composite outcome measure based on the combination of CAL gain and post-surgery PD was evaluated. Factors influencing 1-year CAL gain were analyzed. RESULTS Fifteen patients in MISTms-alone and 16 in the MISTms-combined group finished the study. The MISTms-alone group showed significantly better wound healing at 1 week. CAL significantly gained in the MISTms-alone and MISTms-combined group, with 2.53 ± 1.80 mm and 2.00 ± 1.38 mm respectively. The radiographic bone gain was 3.00 ± 1.56 mm and 3.85 ± 1.69 mm respectively. However, there were no significant differences between the two groups about 1-year outcomes. Lower EHI (optimal wound healing) and more baseline CAL positively influenced 1-year CAL gain. CONCLUSIONS MISTms is an effective treatment for intrabony defects. The regenerative materials do not show an additional effect on 1-year outcomes. Early wound healing and baseline CAL are factors influencing 1-year CAL gain. CLINICAL RELEVANCE MISTms with and without regenerative materials are both effective treatments for intrabony defect. TRIAL REGISTRATION ClinicalTrials.gov Identifier: ChiCTR2100043272.

Abstract
Objective: The aim was to evaluate the efficacy of periodontal regenerative therapy using enamel matrix derivatives (EMDs) in aggressive periodontitis patients, and to determine the contribution of maintenance via periodic supportive periodontal treatment. Method and materials: In total, 28 patients were evaluated, comprising 74 intrabony sites. In 50 sites EMD gel was applied, and in 24 sites EMD was combined with deproteinized bovine xenograft. Patients were assigned to a supportive periodontal treatment program; 18 patients fulfilled the program, defined as the well-maintained (WM) group; 10 did not comply, defined as the nonmaintained (NM) group. Probing depth (PD), clinical attachment level (CAL), and radiographic bone level (BL) were recorded. Data were compared presurgically (T0), 6 months postsurgery (T1), and 3 to 10 years posttreatment (T2). Results: Both surgical modalities achieved similar PD reduction, CAL gain, and BL gain, maintained over time. T1 to T2 showed a mean gain/loss of 0.21 ± 0.5 mm and 0.04 ± 1.1 mm, and -0.65 ± 3.0 mm and -0.73 ± 3.0 mm for PD and CAL, respectively, at the WM/NM groups, respectively. BL gain was 21.6% and 11.5% for the WM/NM groups, respectively (P < .05). The courses of the PD, CAL, and BL differed between the WM and NM groups during the observation periods (P < .05). Conclusion: Periodontal regeneration via EMD with/without the combination of deproteinized bovine xenograft can be maintained in aggressive periodontitis cases. It appears that periodic supportive periodontal treatment is a determinant factor in achieving this task.

Abstract
AIM Horizontally impacted mandibular molars may cause loss of bone, and development of periodontal pockets on the distal root surface of adjacent second molars. The reported patient was confirmed to have aggressive periodontitis. The aim of this presentation is to describe a novel view of a complex treatment approach to promote periodontal healing in a patient. MATERIAL AND METHODS Our study presents the results of a patient with generalized aggressive periodontitis, horizontally impacted left third mandibular molar, and a second molar with a deep periodontal pocket. The treatment concept was recommended based on the idea of "one-stage treatment". The removal of the third molar was followed by deep scaling and root planing, and the xenogenic grafting material was placed on the bone defect. The flap completely covered the wound. The patient received systemic antibiotics. RESULTS The probing pocket depth was 9 mm before surgical treatment and 0-2 mm 1, 5, and 10 years postoperatively. The radiographic bone level was 50 % before surgery and 100 % after the surgical approach. CONCLUSION This presentation with a 10-year follow-up describes the implementation of one-stage treatment management to promote periodontal healing in a patient via full-mouth periodontal and surgical therapy (Fig. 4, Ref. 33).

Abstract
PURPOSE To evaluate the clinical effect of Nd:YAP laser in periodontal regeneration surgery. METHODS Four weeks after primary periodontal treatment, 48 patients, 60 teeth with bone defect and probing depth(PD) ≥6 mm, bleeding on probing (BOP)(+), were randomly divided into two groups. Patients in the experimental group were treated with Nd:YAP laser combined with periodontal regeneration surgery, while patients in the control group were treated with conventional periodontal regeneration surgery alone. Visual analogue scale(VAS) score was used to evaluate the pain degree of patients 24 hours and 3 days after surgery. The probing depth(PD) and clinical attachment loss(CAL) were examined before and 6 months after surgery, and preoperative and postoperative X-ray images of the two groups were observed and compared. SPSS 26.0 software package was used for statistical analysis. RESULTS Twenty-four hours and 3 days after surgery, the pain in the experimental group was significantly less than that in the control group (P<0.001), and PD and CAL levels in the two groups were significantly lower 6 months after surgery than before surgery (P<0.001). There was no significant difference in PD and CAL between the two groups before surgery, and the difference was statistically significant 6 months after surgery(P<0.001). X-ray images showed different degrees of new bone formation in alveolar bone defects in the two groups 6 months after surgery. CONCLUSIONS The application of Nd:YAP laser in periodontal regeneration surgery can reduce postoperative pain and improve the surgical efficacy.

Abstract
AIM The aim of this study is to investigate the effectiveness of a combination of an equine-derived, enzyme-treated bone graft and an equine collagen membrane to treat intrabony defects caused by periodontitis. MATERIALS AND METHODS About 22 patients with a single 1-, 2-, or 3-wall intrabony defect and a probing pocket depth (PPD) of ≥5 mm, who were treated using an enzyme-deantigenated equine bone graft in addition to a collagen membrane and were followed up for at least 10 years, were retrospectively assessed. The plaque index (PI), the sulcus bleeding index (SBI), PPD, and the clinical attachment level (CAL) at each follow-up visit were compared to baseline. RESULTS The mean PI, SBI, PPD, and CAL were 0.22 ± 0.41, 1.86 ± 0.78, 7.86 ± 1.39 mm, and 8.84 ± 1.86 mm, respectively, at baseline, and 0.25 ± 0.44, 0.12 ± 0.32, 2.59 ± 0.50, and 4.04 ± 0.77 mm, respectively, at the last follow-up. The difference was significant for all parameters (p < 0.001) except PI (p = 0.83). The final CAL gain was 4.8 mm (49.8%). The SBI, PPD, and CAL still significantly improved at the 12-month follow-up visit but not at the 24-month follow-up visit. There were no correlations between either the number of defect walls or smoking and outcomes. In one case, a surgical re-entry at 5 years allowed a clinical evaluation, showing that intrabony defect was repaired with the newly formed bone of the patient. CONCLUSION Equine bone granules in addition to an equine collagen membrane effectively and safely treated intrabony defects caused by periodontitis providing long-term results. CLINICAL SIGNIFICANCE Equine-derived bone grafts have been in the market for more than 20 years. However, to the author's knowledge, no studies have reported long-term results for the use of this type of bone graft in periodontal surgery. The equine-derived bone granules used in the present study appears a promising option for treating intrabony defects due to moderate to severe periodontitis.

Abstract
BACKGROUND AND OBJECTIVES Applications of porous titanium granule (PTG) in periodontal (furcation defects) and non-periodontal treatments have shown promising results. However, its role in periodontal intrabony defects still remains unexplored. Thus, we aim to assess the feasibility of PTG in obtaining reconstruction in intrabony defects and compare the outcome with that of open flap debridement (OFD). METHODS Ten patients (three females and seven males) with a mean age of 34.7 years who constituted twenty (20) bilateral intrabony defects were recruited. Each patient contributed to two defects which were randomly treated by OFD alone (control group) or by OFD followed by grafting with PTG (test group). All the clinical and radiological parameters were recorded at baseline, three, six and nine months and statistically analyzed. RESULTS The results of this study demonstrated that in clinical parameters there is no significant differences in the improvement from baseline to nine months. However, regarding the radiographic defect fill, there was significant gain from baseline to nine months only in the PTG sites. CONCLUSION Within the limits of our study, the results of this trial indicate that reconstructive periodontal surgery with PTG offers minimal radiographic defect resolution with no significant improvements in clinical endpoints compared to open flap debridement.

Abstract
OBJECTIVES Regeneration of intrabony defects is a challenging target of periodontal therapy. The biologic rationale for regeneration not only is based on incorporating the regenerative material, but also takes into consideration the defect's inherent healing capacity. The present study was carried out to evaluate the efficacy of decortication or intramarrow penetration performed with demineralized freeze-dried bone allograft (DFDBA) in the management of intrabony defects. METHOD AND MATERIALS Forty chronic periodontitis (stage II and III periodontitis) patients having 40 intrabony defects were randomly assigned into test group (intrabony defect filled with DFDBA after intramarrow penetration along with open flap debridement [OFD+IMP+ DFDBA]) and control group (DFDBA along with open flap debridement [OFD+DFDBA]). Primary outcome measures included probing pocket depth, clinical attachment level, and percentage bone fill (%BF). All parameters were recorded at baseline, 6 months, and 9 months postsurgical follow-up. RESULTS Mean reduction in probing depth and gain in clinical attachment level was statistically significantly higher at the interdental defect site in the test group compared to the control group at 9 months follow-up (P = .02 and .04, respectively). In radiographic parameters, statistically significant improvements in defect depth and gain in defect area were found in the test group (P = .00 and .03, respectively). Statistically significant improvements in %BF and linear bone growth (P = .02 and .00, respectively) were also observed in the experimental group (39.47 ± 13.92% and 1.41 ± 0.54 mm) in comparison with the control group (19.29 ± 14.24%, 0.62 ± 0.49 mm). CONCLUSION Addition of intramarrow penetration with DFDBA in surgical periodontal therapy may enhance the healing potential of periodontal intrabony defects, as observed by greater improvement in clinical and radiographic outcomes.

Abstract
The present study was performed to evaluate the impact of smoking status on 6-month clinical outcomes of a regenerative procedure based on enamel matrix derivative and deproteinized bovine bone mineral in the treatment of intraosseous defects accessed with buccal single flap approach. A total of 22 defects were selected in smoking (n = 11) and nonsmoking (n = 11) patients. Regenerative treatment resulted in similar clinical attachment level (CAL) gain in both smokers and nonsmokers. A trend toward lower 6-month CAL gain and probing depth reduction was observed in patients smoking 11 to 20 cigarettes per day compared to those smoking 1 to 10 cigarettes per day.

Abstract
Dental treatment for periodontally compromised patients can be highly complicated and challenging. This article addresses the effectiveness of contemporary periodontal treatment modalities by depicting clinical cases of periodontal restoration and health that have been maintained for 20 or more years. The cases incorporate four key steps vital to achieving successful treatment of chronic adult periodontitis: debridement, occlusal stabilization, pocket elimination, and maintenance. These cases demonstrate proof of principle that if the treatment is carefully planned and executed precisely, the natural dentition can be maintained for long periods of time even in periodontally compromised patients.

Abstract
Many papillary preservation flap techniques exist for both resective and regenerative purposes. This article describes a papillary retention design based on palatal access showing a successful long-term outcome. The papilla preservation approach detailed here, which is a modification of Friedman's beveled flap for the palate, circumvents any manipulation of interproximal or buccal tissue, leaving papillary tissue untouched. Indications for this approach are very specific and its application is somewhat limited. However, the aim of the papillary retention flap as discussed is to eradicate pocket depths exceeding 5 mm and possibly regenerate hard and connective tissue in these exclusive locations. This strategy may permit access to the labial portion of the interproximal root in particular cases.

Abstract
Volumetric changes were evaluated to assess the regenerative efficacy of demineralized freeze-dried bone allograft (DFDBA) with and without amnion membrane (AM) in Grade II furcation defects both clinically and radiographically using cone beam computed tomography (CBCT). Sites were randomly assigned to Group I (DFDBA) and Group II (DFDBA + AM). Clinical parameters such as probing pocket depth, clinical attachment level, gingival recession, and horizontal probing depth were assessed at baseline, 3 months, and 6 months. Radiographic dimensions of the defect height, width, depth, and volume were assessed at baseline and 6 months postoperatively. DFDBA used with AM resulted in significant improvement in clinical and radiographic parameters when compared with DFDBA alone. The mean reductions in radiographic volume of the defect were 11.15 ± 6.39 mL for Group I and 17.02 ± 10.86 mL for Group II. Greater reduction in volume indicated a greater amount of healed regenerated tissue in Group II patients.

Abstract
The ultimate goal of periodontal therapy is to prevent further disease progression in order to reduce the risk of tooth loss. This objective can be achieved through a number of therapeutic modalities comprising both the nonsurgical and surgical phases of periodontal therapy. Nonsurgical periodontal treatment has been shown to control periodontal infection and to arrest progression of the disease in a significant number of cases. However, despite completion of nonsurgical treatment, a number of periodontal pockets, defined as 'residual', often remain. The presence of residual pockets may jeopardize tooth survival and be a risk factor of further disease progression, and ultimately tooth loss. Therefore, the aim of this review is to analyze the knowledge available on the indications for and the performance of periodontal surgical treatment of residual pockets in terms of 'traditional' (clinical, microbiological), patient-based and systemic health outcomes.

Abstract
The aim of this study was to report the 1-year clinical outcomes from videoscope-assisted minimally invasive surgery (V-MIS). A sample of 18 patients having sites with residual pocket probing depth (PPD) of at least 5 mm and 2 mm loss in clinical attachment level (CAL) following initial nonsurgical therapy were treated with V-MIS. At 12 months postsurgery, there was a statistically significant improvement (P < .001) in mean PPD (4.11 ± 0.98 mm) and CAL (4.58 ± 1.19 mm) in all surgical sites. A mean improvement in soft tissue height (0.48 ± 0.65 mm, P = .006) was also observed. In most cases, patients reported no postoperative discomfort. The improvements associated with V-MIS appear to be favorable when compared with previously reported results of periodontal regenerative surgery. The lack of postsurgical recession following V-MIS has not been reported with traditional regenerative surgery.

Abstract
OBJECTIVE To evaluate the clinical efficacy of a new porcine acellular dermal matrix (PADM) for the treatment of Miller Class I, II, and III multiple gingival recessions using the modified coronally advanced tunnel technique (MCAT). METHOD AND MATERIALS Twelve nonsmoking, systemically healthy patients presenting at least two adjacent Miller Class I, II, or III gingival recessions (GR), with a minimal depth of 2 mm, were treated consecutively with MCAT in conjunction with PADM. At baseline and 12 months postoperatively, complete root coverage (CRC, eg 100% root coverage), mean root coverage (RC), recession depth, recession width, attached gingiva (AG), keratinized tissue (KT), periodontal pocket depths (PD), and clinical attachment level (CAL) were evaluated. The main outcome variable was CRC. RESULTS Postoperative healing was uneventful in all cases, without any matrix loss or exposure or infection. Statistically significant improvements (P < .0001) were observed 12 months postoperatively in 53 of the included 54 GR (98.15%). Twenty two recessions (40.74%) showed CRC while the mean RC measured 73.20 ± 27.71%. Mean GR reduction was 2.06 ± 1.18 mm while the gain of AG amounted to 0.84 ± 0.73 mm and of KT to 0.69 ± 0.51 mm, respectively. There were no statistically significant changes for PD at 12 months; CAL showed a significant decrease (P < .05) at 12 months from 3.77 ± 1.28 mm to 2.30 ± 1.02 mm. CONCLUSION PADM in conjunction with MCAT may be successfully utilized for the treatment of Miller Class I, II, and III multiple adjacent GR.

Abstract
PURPOSE As dental implants have become routine therapy, clinicians are more frequently being faced with treating peri-implantitis. To date, no single treatment protocol has been shown to be the preferred means to treat peri-implantitis. The aim of this retrospective case series is to present a novel approach utilizing porcine collagen-coated bovine bone (CBB) to treat peri-implantitis. MATERIALS AND METHODS Eleven patients, with no history of periodontitis, presenting with peri-implantitis around a single restored dental implant, were included in the study. At initial and follow-up examinations, bleeding on probing (BOP), probing depth (PD), and gingival margin location (GM) were recorded. Following surgical debridement of the peri-implant defect and treatment of the implant surface with a 0.12% chlorhexidine gluconate solution, bony defects were grafted with CBB. All patients had 12 months of follow-up. RESULTS Upon presentation, average PD at the deepest site (DS) was 7.6 ± 1.9 mm. At the time of surgery, excess cement was found around nine implants (81%). All patients healed uneventfully without postoperative complications. At 6 and 12 months, all implants showed favorable results with average DS PD reduction of 3.9 ± 1.5 mm and 4.1 ± 1.6 mm, respectively. All implants showed radiographic signs of bone fill, while GM showed no changes from preoperative measurements at either 6 (0.1 ± 0.5 mm) or 12 (0.0 ± 0.6 mm) months. CONCLUSION The use of a porcine collagen-coated bovine bone graft to treat peri-implantitis represents a potentially predictable therapeutic modality. Randomized controlled trials are necessary to substantiate the treatment outcomes.

Abstract
OBJECTIVES The aim of this study is to report on the treatment of mandibular Class II furcation defects with enamel matrix protein derivative (EMD) combined with a βTCP/HA (β-tricalcium phosphate/hydroxyapatite) alloplastic material. METHOD AND MATERIALS Thirteen patients were selected. All patients were nonsmokers, systemically healthy, and diagnosed with chronic periodontitis; had not taken medications known to interfere with periodontal tissue health and healing; presented one Class II mandibular furcation defect with horizontal probing equal to or greater than 4 mm at buccal site. The clinical parameters evaluated were probing depth (PD), relative gingival margin position (RGMP), relative vertical clinical attachment level (RVCAL), and relative horizontal clinical attachment level (RHCAL). A paired Student t test was used to detect differences between the baseline and 6-month measurements, with the level of significance of .05. RESULTS After 6 months, the treatment produced a statistically significant reduction in PD and a significant gain in RVCAL and RHCAL, but no observable change in RGMP. RVCAL ranged from 13.77 (± 1.31) at baseline to 12.15 (± 1.29) after 6 months, with a mean change of -1.62 ± 1.00 mm (P < .05). RHCAL ranged from 5.54 (± 0.75) to 2.92 (± 0.92), with a mean change of -2.62 ± 0.63 mm (P < .05). After 6 months, 76.92% of the patients improved their diagnosis to Class I furcation defects while 23.08% remained as Class II. CONCLUSION The present study has shown that positive clinical results may be expected from the combined treatment of Class II furcation defects with EMD and βTCP/HA, especially considering the gain of horizontal attachment level. Despite this result, controlled clinical studies are needed to confirm our outcomes.

Abstract
The practitioner may have difficulties making decisions regarding the most appropriate therapeutic approach in the case of the persistence of periodontal pockets after initial periodontal treatment. Several options may be considered: aetiologic retreatment, maintenance, surgery of the pocket or extraction of the tooth for strategic reasons or when the conservation of the tooth is impossible. There are no clear guidelines for the treatment decision. The aim of this article is to present the main factors involved in making a treatment decision. An algorithm and its background rationale are presented to help the practitioner make a decision about residual periodontal pockets after aetiological treatment.

Abstract
PURPOSE The purpose of this 6-month randomized, controlled, blinded, clinical trial was to evaluate and compare the efficacy of amnion membrane (AM) with deproteinized bovine bone mineral (BBM) and a collagen membrane (CM) with BBM in guided tissue regeneration (GTR) for the treatment of intrabony periodontal defects. MATERIALS AND METHODS Ten chronic periodontitis patients with bilateral intrabony defects with radiographic evidence of intrabony component ≥ 4 mm and probing pocket depths (PPDs) ≥ 6 mm were treated with AM+BBM, and the control group was managed with CM+BBM. Periodontal clinical parameters were recorded at baseline and at 6 months after treatment. RESULTS PPD, clinical attachment level (CAL), and probing bone (PB) showed significant improvements after 6 months in both the test and control groups. Gingival recession showed a significant increase in the control group but not in the test group. The changes in mean PPD, PB, and CAL preoperatively and postoperatively between the groups were not significant. There was no significant relationship between the depth of the baseline bony defect and CAL gain. CONCLUSION Both AM and CM in conjunction with BBM provided improvement of clinical periodontal parameters. AM did not induce significant gingival recession and is suggested as a new barrier membrane in GTR treatment.

Abstract
INTRODUCTION Flared and elongated incisors are associated with different types of periodontal bone defects, usually horizontal. Combined orthodontic-periodontal treatment is being used in periodontal patients with anterior displacement of the incisors. The purpose of this study was to investigate the changes in periodontal health and the shape of bone defects in the incisors after such combined treatment. METHODS Fourteen adults were included in the study. In total, 56 elongated maxillary incisors with horizontal bone defects received orthodontic-periodontal treatment with circumferential supracrestal fibrotomy. To improve bone morphology, periodontal regenerative surgery and guided tissue regeneration were performed on the anterior teeth with angular bone defects after orthodontic treatment. Cone-beam computed tomography scans were taken before treatment (T0), at the end of the orthodontic intrusion (T1), and 6 months after the guided tissue regeneration surgery (T2). Probing pocket depth and clinical attachment loss were examined at T0, T1, and T2. The data were analyzed using paired t tests. RESULTS From T0 to T1, clinical attachment loss decreased significantly by 0.29 mm (P <0.05). The distance from the cementoenamel junction to the marginal bone crest decreased by 0.66 mm (P <0.05). The labial side of alveolar bone thickness increased by 0.54 mm (P <0.05), and the lingual side of alveolar bone thickness decreased by 0.46 mm (P <0.05). The shape of the bone defect was changed from horizontal to vertical on some teeth. From T1 to T2, both probing pocket depth and clinical attachment loss improved significantly, and the radiographic examinations showed bone redepositions of 2.15 ± 0.68 mm (P <0.05) vertically and 1.44 ± 0.92 mm (P <0.05) horizontally. The distance from the most apical point of the bone defect to the cementoenamel junction after combined treatment decreased by 2.11 ± 1.30 mm (P <0.05). CONCLUSIONS Combined orthodontic-periodontal treatment improved the periodontal conditions of the defective bone sites. Bone morphology, altered by orthodontic intrusion with fibrotomy, can improve the results of subsequent guided tissue regeneration.

Abstract
There is scarce evidence on suitable approaches for the treatment of unresponsive or residual periodontal sites in diabetic patients. This study assessed the effects of surgical debridement (SD) and nonsurgical debridement (NSD), associated with amoxicillin and metronidazole, on clinical and immunological outcomes of residual pockets and adjacent healthy sites in patients with type 2 diabetes. A split-mouth, randomized controlled trial was conducted in 21 patients presenting at least 2 residual pockets in contralateral quadrants 12 months after basic nonsurgical periodontal therapy. Patients received systemic antibiotics, and contralateral quadrants were assigned to receive SD or NSD. The changes in clinical parameters were evaluated from baseline to 12 months. Local levels of 14 cytokines and chemokines were measured with multiplex bead immunoassays at baseline and 3 and 12 months after therapy. There were no statistically significant differences between SD and NSD for changes in clinical parameters from baseline to 12 months (P > 0.05). There was a significantly greater increase in the levels of granulocyte-macrophage colony-stimulating factor and interleukin 6 from baseline to 3 months in the healthy sites adjacent to residual pockets receiving SD (P < 0.05). A significant decrease in the levels of monocyte chemoattractant protein-1 and macrophage inflammatory protein 1α occurred from baseline to 12 months in the residual pockets treated by SD (P < 0.05). In conclusion, SD and NSD resulted in similar clinical benefits at 12 months. The short-term increase in the levels of proinflammatory biomarkers in SD sites probably can be attributed to tissue trauma and healing, and the long-term decrease in the levels of chemotactic factors in residual pockets treated by surgery may reflect remission of infection and stable wound healing in these sites at 12 months.

Abstract
Aggressive periodontitis (AgP) is an inflammatory disease characterized by rapid attachment loss and bone destruction. This case report presents the 10-year results in a subject with generalized AgP treated by a regenerative periodontal therapeutic approach and the adjunctive use of antibiotics, following a systematic maintenance periodontal therapy. The use of enamel matrix derivatives (EMD) and adjunctive antibiotic therapy to treat AgP yielded improvements in clinical parameters and radiographic bony fill. This combined therapeutic approach following a systematic supportive periodontal therapy supports the long-term maintenance of teeth with previous advanced periodontal defects, demonstrating successful stability after 10-years follow-up. Clinical Relevance: The combined treatment protocol using EMD plus adjunctive antibiotic therapy, associated with a systematic supportive periodontal therapy, benefits the long-term maintenance of teeth with previous advanced periodontal defects in subjects presenting AgP, supporting this approach as an alternative in the treatment of AgP.

Abstract
BACKGROUND AND AIM There is a lack of suitable in vitro models to evaluate various treatment modalities intending to remove subgingival bacterial biofilm. Consequently, the aims of this in vitro-study were: a) to establish a pocket model enabling mechanical removal of biofilm and b) to evaluate repeated non-surgical periodontal treatment with respect to biofilm removal and reformation, surface alterations, tooth hard-substance-loss, and attachment of periodontal ligament (PDL) fibroblasts. MATERIAL AND METHODS Standardized human dentin specimens were colonized by multi-species biofilms for 3.5 days and subsequently placed into artificially created pockets. Non-surgical periodontal treatment was performed as follows: a) hand-instrumentation with curettes (CUR), b) ultrasonication (US), c) subgingival air-polishing using erythritol (EAP) and d) subgingival air-polishing using erythritol combined with chlorhexidine digluconate (EAP-CHX). The reduction and recolonization of bacterial counts, surface roughness (Ra and Rz), the caused tooth substance-loss (thickness) as well as the attachment of PDL fibroblasts were evaluated and statistically analyzed by means of ANOVA with Post-Hoc LSD. RESULTS After 5 treatments, bacterial reduction in biofilms was highest when applying EAP-CHX (4 log10). The lowest reduction was found after CUR (2 log10). Additionally, substance-loss was the highest when using CUR (128±40 µm) in comparison with US (14±12 µm), EAP (6±7 µm) and EAP-CHX (11±10) µm). Surface was roughened when using CUR and US. Surfaces exposed to US and to EAP attracted the highest numbers of PDL fibroblasts. CONCLUSION The established biofilm model simulating a periodontal pocket combined with interchangeable placements of test specimens with multi-species biofilms enables the evaluation of different non-surgical treatment modalities on biofilm removal and surface alterations. Compared to hand instrumentation the application of ultrasonication and of air-polishing with erythritol prevents from substance-loss and results in a smooth surface with nearly no residual biofilm that promotes the reattachment of PDL fibroblasts.

Abstract
OBJECTIVE Polypeptide growth factors of platelet rich fibrin (PRF) have the potential to regenerate periodontal tissues. Osteoinductive property of demineralized freeze-dried bone allograft (DFDBA) has been successfully utilized in periodontal regeneration. The aim of the present randomized, split mouth, clinical trial was to determine the additive effects of PRF with a DFDBA in the treatment of human intrabony periodontal defects. MATERIALS AND METHODS Sixty interproximal infrabony defects in 30 healthy, non-smoker patients diagnosed with chronic periodontitis were randomly assigned to PRF/DFDBA group or the DFDBA/saline. Clinical [pocket depth (PD), clinical attachment level (CAL) and gingival recession (REC)] and radiographic (bone fill, defect resolution and alveolar crest resorption) measurements were made at baseline and at a 12-month evaluation. RESULTS Compared with baseline, 12-month results indicated that both treatment modalities resulted in significant changes in all clinical and radiographic parameters. However, the PRP/DFDBA group exhibited statistically significantly greater changes compared with the DFDBA/saline group in PD (4.15 ± 0.84 vs 3.60 ± 0.51 mm), CAL (3.73 ± 0.74 vs 2.61 ± 0.68 mm), REC (0.47 ± 0.56 vs 1.00 ± 0.61 mm), bone fill (3.50 ± 0.67 vs 2.49 ± 0.64 mm) and defect resolution (3.73 ± 0.63 vs 2.75 ± 0.57 mm). CONCLUSION Observations indicate that a combination of PRF and DFDBA is more effective than DFDBA with saline for the treatment of infrabony periodontal defects.

Abstract
OBJECTIVES This study was designed to describe and evaluate the use of a vascularized marginal periosteal barrier membrane (MPM) harvested by a semilunar incision, alone or combined with a bone graft, in treatment of class II furcation defects in mandibular molars, compared to open flap debridement (OFD). METHODS Thirty class II furcation defects in mandibular molars were randomly assigned into three equal groups: Group I included OFD, Group II included defects treated with MPM, and Group III consisted of defects treated with MPM after applying demineralized freeze-dried bone allograft (DFDBA). At baseline and 6-month follow-up, vertical probing depth (VPD), clinical attachment level (CAL) measurements, along with a radiographic measurement of bone height (BH), were obtained for each defect. Transmission electron microscopy (TEM) was used for further evaluation of the histological changes associated with gingival samples related to each line of treatment. RESULTS Both Groups II and III reflected significant favorable outcomes in all the assessed parameters compared to OFD. A non-significant difference was found between both groups regarding VPD, while significant improvement in CAL and BH were detected in Group III (p ≤ 0.05). Favorable histological findings were also noticed in the test groups, with more improvement in Group III. CONCLUSION Placement of a vascularized MPM as a barrier membrane, using a semilunar incision, demonstrated a significant improvement in both clinical and histological outcomes of class II furcation defects in lower molars. When it was combined with DFDBA, a meaningful difference was found with regard to early wound healing and gain in CAL and BH.

Abstract
OBJECTIVE To evaluate and compare the efficacy of platelet-rich fibrin (PRF) with enamel matrix derivative (EMD; Emdogain) in the treatment of periodontal intrabony defects in patients with chronic periodontitis, six months after surgery. METHODS Forty-four (44) intrabony defects in 30 patients (15 males) were randomly allocated into two treatment groups: EMD (n = 22) and PRF (n = 22). Measurement of the defects was done using clinical and cone beam computed tomography at baseline and 6 months. Clinical and radiographic parameters such as probing depth, clinical attachment level, intrabony defect depth and defect angle, were recorded at baseline and 6 months post-operatively. Within group change was evaluated using the Wilcoxon signed rank test. Intergroup comparisons were made using the Mann-Whitney U test. RESULTS Postsurgical measurements revealed that there was an equal reduction in probing depth and a greater but statistically non-significant attachment gain for the Emdogain group when compared to the platelet-rich fibrin group. The Emdogain group presented with significantly greater percentage defect resolution (43.07% ± 12.21) than did the platelet-rich fibrin group (32.41% ± 14.61). Post-operatively the changes in defect width and defect angle were significant in both groups, but upon intergroup comparison they were found to be statistically non-significantly different. CONCLUSION Both Emdogain and platelet-rich fibrin were effective in the regeneration of intrabony defects. Emdogain was significantly superior in terms of percentage defect resolution.

Abstract
A treatment option for managing furcation invasions is root amputation. Long-term survival of resected molars requires a complete harmony of sequential endodontic, periodontic, restorative and maintenance procedures. The main objective of this article is to provide a concise historical perspective of this procedure and to review available literature regarding its efficacy and limitations. It also illustrates a current modification of the procedure using guided bone regeneration (GBR) and socket preservation to eliminate some of the potential disadvantages of the traditional root amputation procedure.

Abstract
BACKGROUND Periodontitis is characterized by the formation of true pockets, bone loss and attachment loss. Various techniques have been attempted in the past to truly regenerate the lost periodontal structures, albeit with variable outcome. In this evolution, the technique being tried out widely is the use of platelet rich concentrates, namely platelet-rich fibrin (PRF). CASE DESCRIPTION In this report, we present a case of surgical treatment of osseous bone defects namely two walled crater and dehiscence treated in posterior teeth with autologously prepared platelet rich fibrin mixed with hydroxy apatite bone graft and PRF in the form of a membrane. CONCLUSION Our results showed clinical improvements in all the clinical parameters postoperatively namely the pocket depth reduction and gain in attachment level and hence, PRF can be used alone or in combination with the bone graft to yield successful clinical results in treating periodontal osseous defects. CLINICAL SIGNIFICANCE Platelet-rich fibrin is an effective alternative to platelet-rich plasma (PRP) in reconstructing bone defects.

Abstract
This review aims to highlight concepts relating to nonsurgical and surgical periodontal therapy, which have been learned and unlearned over the past few decades. A number of treatment procedures, such as gingival curettage and aggressive removal of contaminated root cementum, have been unlearned. Advances in technology have resulted in the introduction of a range of new methods for use in nonsurgical periodontal therapy, including machine-driven instruments, lasers, antimicrobial photodynamic therapy and local antimicrobial-delivery devices. However, these methods have not been shown to offer significant benefits over and above nonsurgical debridement using hand instruments. The method of debridement is therefore largely dependent on the preferences of the operator and the patient. Recent evidence indicates that specific systemic antimicrobials may be indicated for use as adjuncts to nonsurgical debridement in patients with advanced disease. Full-mouth disinfection protocols have been proven to be a relevant treatment option. We have learned that while nonsurgical and surgical methods result in similar long-term treatment outcomes, surgical therapy results in greater probing-depth reduction and clinical attachment gain in initially deep pockets. The surgical technique chosen seems to have limited influence upon changes in clinical attachment gain. What has not changed is the importance of thorough mechanical debridement and optimal plaque control for successful nonsurgical and surgical periodontal therapy.

Abstract
This review aimed at evaluating the effectiveness of reconstructive procedures for treating peri-implantitis. Searches of electronic databases and cross-referencing were performed for human comparative clinical trials with ≥ 10 implants for ≥ 12 months of follow-up, reporting radiographic defect fill and at least one of the following parameters: probing depth reduction, clinical attachment level gain, bleeding on probing reduction, and mucosal recession. The searches retrieved 430 citations. Only 1 randomized controlled trial was identified, which compared reconstructive therapy and open flap debridement. Case series studies were also included to evaluate the overall performance of the reconstructive procedures. Twelve studies were finally included. Meta-analysis revealed that the weighted mean radiographic defect fill was 2.17 mm (95% confidence interval [CI]: 1.46-2.87 mm), probing depth reduction was 2.97 mm (95% CI: 2.38-3.56 mm), clinical attachment level gain was 1.65 mm (95% CI: 1.17-2.13 mm), and bleeding on probing reduction was 45.8% (95% CI: 38.5%-53.3%). Great variability in reparative outcomes was found, attributed to patient factors, defect morphology, and reconstructive agents used. Currently, there is a lack of evidence for supporting additional benefit of reconstructive procedures to the other treatment modalities for managing peri-implantitis.
