Periodontitis stage and grade modifies the benefit of regular supportive periodontal care in terms of need for retreatment and mean cumulative cost. J Clin Periodontol 2024; 51:167-176. [PMID: 38084661 DOI: 10.1111/jcpe.13909] [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: 06/06/2023] [Revised: 10/03/2023] [Accepted: 11/11/2023] [Indexed: 01/19/2024]
Abstract
AIM This study aimed to characterize the periodontal breakdown during supportive periodontal care (SPC) and to quantify the corresponding cost-effectiveness of periodontal therapy. MATERIALS AND METHODS Data were obtained from charts of patients who received active periodontal therapy (APT) with a minimum follow-up of ≥10 years. Analysis was done to identify factors associated with the incidence of additional sub-gingival instrumentation (SGI) and/or surgery (SUR) during SPC and mean cumulative cost of recurrence was calculated. All relevant data were collected. RESULTS In all, 442 patients were included. Over the follow-up period, 62% of Stage I and II patients and 72% of Stage III and IV patients required further treatment following the APT; 56.5% of SGI patients and 78.6% of SUR patients received a second intervention. SUR patients received more SUR during the follow-up period (p = .035). Stage III and IV patients received more SUR during SPC than Stage I and II patients (p = .001). Grade C patients received more SUR during the follow-up period (p < .05). During the 5-year period preceding retreatment, the mean SPC visits were lower for patients who did not require retreatment (p < .001). Risk factors such as regularity of maintenance, smoking and diabetes were related to a higher chance of receiving SUR during the follow-up period (p < .05). The mean cumulative costs indicated less recurrence cost for compliers in Stage III and IV or Grade B and C but not for those in Stage I and II or Grade A. CONCLUSIONS The risk of relapse in the maintenance population may be correlated with higher stage and grade, patient compliance, modifiable risk factors and the nature of the treatment provided during APT. The total cost of treatment of recurrences was lower for compliers in Stage III/IV and Grade B/C compared with erratic compliers with the same severity and risk.

Denture use and risk for cardiometabolic disease: observational and Mendelian randomization analyses. Eur J Prev Cardiol 2024; 31:13-20. [PMID: 37697428 PMCID: PMC10767255 DOI: 10.1093/eurjpc/zwad295] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2023] [Revised: 08/13/2023] [Accepted: 09/07/2023] [Indexed: 09/13/2023]
Abstract
AIMS Denture use may potentially increase the risk of cardiometabolic diseases (CMDs), but the casual relevance and strength of the associations are currently unknown. METHODS AND RESULTS A total of 495 938 participants from the UK Biobank were included in the observational analyses. Linkage disequilibrium score (LDSC) regression and Mendelian randomization analyses were employed to estimate genetic correlation and the associations between the genetic liability for denture use with coronary artery disease, myocardial infarction, heart failure (HF), any stroke (AS), ischaemic stroke, haemorrhagic stroke, type 2 diabetes (T2D), and related clinical risk factors. In observational analysis, denture use was associated with 14-25% higher risks of various CMDs. The LDSC analysis found that denture use showed a positive genetic correlation with CMDs (rg 0.21-0.38). Genetic liability for denture use was associated with an elevated risk of HF [odds ratio: 1.49 (1.20-1.83)] and T2D [1.11 (1.01-1.24)]. By integrating genetic summary data of denture use with the sum of decayed, missing, and filled tooth surfaces (DMFS), a clinical measure of dental caries obtained from an independent source, genetically determined denture use/DMFS was also associated with an elevated risk of AS [1.21 (1.04-1.40)]. Furthermore, genetically predicted denture use/DMFS was significantly associated with established cardiometabolic risk factors, including HDL cholesterol, triglycerides, waist circumference, waist-to-hip ratio, and height. CONCLUSION Our study supported potential causal associations between the genetic liability for denture use and risks for HF, AS, T2D, and related clinical risk factors. These findings may inform prevention and intervention strategies targeting dental diseases and CMDs.

Involving people with lived experience in developing a core outcome set for implant dentistry research. The Impant Dentistry-Core Outcomes Sets and Measures (ID-COSM) project. J Clin Periodontol 2023; 50 Suppl 25:96-106. [PMID: 37143297 DOI: 10.1111/jcpe.13812] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Revised: 03/20/2023] [Accepted: 03/21/2023] [Indexed: 05/06/2023]
Abstract
AIMS The aims of this project were to establish the outcomes for dental implant research that are important to people with lived experience (PWLE) and to achieve consensus with those developed by dental professionals (DPs) for a core outcome set (COS). This paper reports the process, outcomes and experiences of involving PWLE in developing a COS for dental implant research: the Implant Dentistry Core Outcome Sets and Measures project. MATERIALS AND METHODS Overall methods were guided by the Core Outcome Set Measures in Effectiveness Trials (COMET) initiative. Initial outcome identification was achieved from focus groups with PWLE employing calibrated methods across two low-middle-income countries (China and Malaysia) and two high-income countries (Spain and the United Kingdom). Following consolidation of the results, the outcomes were incorporated into a three-stage Delphi process with PWLE participation. Finally, consensus between PWLE and DPs was achieved using a mixed live and recorded platform. The experiences of PWLE involvement in the process was also evaluated. RESULTS Thirty-one PWLE participated in four focus groups. Thirty-four outcomes were suggested across the focus groups. Evaluation of the focus groups revealed a high level of satisfaction with the engagement process and some new learning. Seventeen PWLE contributed to the first 2 Delphi rounds and 7 to the third round. The final consensus included 17 PWLE (47%) and 19 DPs (53%). Out of the total of 11 final consensus outcomes considered essential by both PWLE and health professionals, 7 (64%) outcomes mapped across to ones that PWLE initially identified, broadening their definition. One outcome (PWLE effort required for treatment and maintenance) was entirely novel. CONCLUSIONS We conclude that engaging PWLE in COS development can be achieved across widely different communities. Furthermore, the process both broadened and enriched overall outcome consensus, yielding important and novel perspectives for health-related research.

Association of the number of natural teeth with dietary diversity and nutritional status in older adults: A cross-sectional study in China. J Clin Periodontol 2023; 50:242-251. [PMID: 36122930 DOI: 10.1111/jcpe.13728] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2022] [Revised: 08/13/2022] [Accepted: 09/14/2022] [Indexed: 01/18/2023]
Abstract
AIM To investigate the association of the number of natural teeth with overall dietary diversity and nutritional status in a nationally representative study among older adults in China. MATERIALS AND METHODS A cross-sectional analysis was conducted among community-dwelling adults aged 65 years or older from the Chinese Longitudinal Healthy Longevity Study. According to the self-reported number of natural teeth, participants were categorized into ≥20, 10-19, 1-9 natural teeth, and edentulous. Dietary diversity score (DDS) was constructed based on intake frequencies of 10 food groups assessed by a simplified food frequency questionnaire. The geriatric nutritional risk index was used to measure the malnutrition status (i.e., normal, mild malnutrition, and moderate-to-severe malnutrition) among a subgroup of participants. Linear and multinomial logistic regression models were used to examine the corresponding associations. RESULTS Among 54,796 study participants, the mean (SD) age was 87.86 (11.45) years, 82.7% had poor dentition (<20 natural teeth), and 27.3% wore dentures. After multivariable adjustment, participants with poor dentition had lower DDSs (βedentulous = -0.39, 95% confidence interval [CI], -0.48, -0.30; β1-9 teeth = -0.46, 95% CI, -0.55, -0.37; β10-19 teeth = -0.36, 95% CI, -0.46, -0.26) than those with 20 natural teeth or more. For individual food items, edentulous, 1-9 and 10-19 natural teeth were associated with lower odds of regular intake of fresh fruits, fresh vegetables, meat, fish and aquatic products, eggs, legumes, preserved vegetables, tea, and garlic, but higher odds of regular intake of sugar and sweets. Among participants with poor dentition, individuals without dentures had lower intake frequencies of most food groups than those wearing dentures. In addition, poor dentition was related to lower odds of normal nutritional status (odds ratio = 0.49, 95% CI, 0.27, 0.89). CONCLUSIONS Older adults with poor dentition had significantly lower dietary diversity and worse nutritional status. Future studies are warranted to identify effective interventions to improve the dietary quality and nutrition status among partially and fully edentulous individuals, including those with Stage IV periodontitis.

Factors affecting periodontal healing of the adjacent second molar after lower third molar surgery: a systematic review and meta-analysis. Clin Oral Investig 2022; 27:1547-1565. [PMID: 36418503 DOI: 10.1007/s00784-022-04777-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/02/2022] [Accepted: 11/06/2022] [Indexed: 11/25/2022]
Abstract
OBJECTIVES This systematic review and meta-analysis aim to evaluate the effect modifiers which may influence the periodontal healing of the adjacent second molar after lower third molar surgery. MATERIALS AND METHODS Prospective studies including patients with third molars requiring removal, with at least 6 months follow-up were considered. Outcomes were periodontal probing depth (PPD) reduction, final PPD, clinical attachment level (CAL) change, final CAL, alveolar bone defect (ABD) reduction, and final ABD depth. Meta-regression was performed to identify factors. RESULTS Fourteen studies were included in the quantitative synthesis. At 6 months, the PPD reduction was 1.06 mm (95% CI, 0.72 to 1.39 mm) and the remaining PPD was 3.81 mm (95% CI, 3.00 to 4.62 mm). Baseline PPD was strongly correlated with the remaining PPD at 6 months (p < 0.001, adjusted R2 = 70.05%). CONCLUSIONS Lower third molar surgery results in a modest reduction in PPD, CAL, and ABD; however, periodontal defects still remain at 6 months and beyond. Baseline PPD is strongly correlated with final PPD. While age is not shown to have effect on most of the periodontal parameters, a larger baseline PPD is more likely to manifest with increasing age and third molar surgery should be done before severe periodontitis occurs to avoid persistent periodontal defects. CLINICAL RELEVANCE This study shows that lower third molar surgery results in modest improvement in periodontal parameters on adjacent second molars and identified factors such as baseline PPD which may affect the healing, which may guide the pre-, peri-, and post-operative management of lower third molar surgery.

Agreement among international periodontal experts using the 2017 World Workshop classification of periodontitis. J Periodontol 2021; 92:1675-1686. [PMID: 34545953 DOI: 10.1002/jper.20-0825] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2020] [Revised: 08/22/2021] [Accepted: 08/27/2021] [Indexed: 12/29/2022]
Abstract
BACKGROUND A new periodontitis classification was recently introduced involving multidimensional staging and grading. The aim of the study was to assess if individuals well-trained in periodontics consistently used the new classification for patients with severe periodontitis. The secondary goal was to identify "gray zones" related to classifications. METHODS Participants (raters) individually classified 10 pre-selected severe periodontitis cases using the 2017 World Workshop classification. An internet case-based study was conducted after inviting members from American Academy of Periodontology and European Federation of Periodontology. Gold-standard diagnoses were determined by five experts who developed the new periodontitis classification. Inter-reliability agreement among raters was assessed using Fleiss Kappa index with the jackknife method for linearly weighted kappa calculations. McNemar test was used to determine symmetry between raters and gold-standard panel. RESULTS A total of 103 raters participated and classified nine clinical cases. Fleiss Kappa values showed moderate inter-examiner consistency among raters for stage (K value: 0.49; 95% CI, 0.19 to 0.79), grade (K value: 0.50; 95% CI, 0.30 to 0.70) and extent (K value: 0.51; 95% CI, 0.23 to 0.77). When analyzed as composite (stage, grade, extent) a moderate inter-reliability was present among raters, k = 0.479 (K value: 0.47; 95% CI, 0.442 to 0.515). Agreement between raters and gold-standard panel was staging 76.6%; grading 82%; and extent 84.8%. In six of nine cases 77% to 99% of raters consistently agreed with gold-standard panel, and the other three cases had gray zone factors that reduced rater consistency. CONCLUSIONS Clinicians trained in the 2017 World Workshop periodontitis classification demonstrated moderate concordance in classifying nine severe periodontitis cases, and in six of nine cases raters consistently agreed with the gold-standard panel.

Medium- and long-term clinical benefits of periodontal regenerative/reconstructive procedures in intrabony defects: Systematic review and network meta-analysis of randomized controlled clinical studies. J Clin Periodontol 2021; 48:410-430. [PMID: 33289191 PMCID: PMC7986220 DOI: 10.1111/jcpe.13409] [Citation(s) in RCA: 39] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2019] [Revised: 10/26/2020] [Accepted: 11/24/2020] [Indexed: 12/20/2022]
Abstract
BACKGROUND Systematic reviews have established the short-term improvements of periodontal regenerative/reconstructive procedures compared to conventional surgical treatment in intrabony defects. However, a hierarchy of periodontal regenerative/reconstructive procedures regarding the medium- to long-term results of treatment does not exist. AIM To systematically assess the literature to answer the focused question "In periodontitis patients with intrabony defects, what are the medium- and long-term benefits of periodontal regenerative/reconstructive procedures compared with open flap debridement (OFD), in terms of clinical and/or radiographic outcome parameters and tooth retention?". MATERIAL & METHODS Randomized controlled clinical trials (RCTs), reporting on clinical and/or radiographic outcome parameters of periodontal regenerative/reconstructive procedures ≥3 years post-operatively, were systematically assessed. Clinical [residual probing pocket depth (PD) and clinical attachment level (CAL) gain, tooth loss] and radiographic [residual defect depth (RDD), bone gain (RBL)] outcome parameters were assessed. Descriptive statistics were calculated, and Bayesian random-effects network meta-analyses (NMA) were performed where possible. RESULTS Thirty RCTs, presenting data 3 to 20 years after treatment with grafting, GTR, EMD, as monotherapies, combinations thereof, and/or adjunctive use of blood-derived growth factor constructs or with OFD only, were included. NMA based on 21 RCTs showed that OFD was clearly the least efficacious treatment; regenerative/reconstructive treatments resulted in significantly shallower residual PD in 4 out 8 comparisons [range of mean differences (MD): -2.37 to -0.60 mm] and larger CAL gain in 6 out 8 comparisons (range of MD: 1.26 to 2.66 mm), and combination approaches appeared as the most efficacious. Tooth loss after regenerative/reconstructive treatment was less frequent (0.4%) compared to OFD (2.8%), but the evidence was sparse. There were only sparse radiographic data not allowing any relevant comparisons. CONCLUSION Periodontal regenerative/reconstructive therapy in intrabony defects results, in general, in shallower residual PD and larger CAL gain compared with OFD, translating in high rates of tooth survival, on a medium (3-5 years) to long-term basis (5-20 years). Combination approaches appear, in general, more efficacious compared to monotherapy in terms of shallower residual PD and larger CAL gain. A clear hierarchy could, however, not be established due to limited evidence.

Periodontal infrabony defects: Systematic review of healing by defect morphology following regenerative surgery. J Clin Periodontol 2020; 48:100-113.

Abstract
BACKGROUND It is thought that infrabony defect morphology affects the outcome of periodontal regenerative surgery. However, this has not been systematically investigated. AIMS To investigate how well defect morphology is described in papers reporting regenerative therapy of periodontal infrabony defects and to investigate its effect on clinical and radiographic outcomes. MATERIALS AND METHODS A search was conducted in 3 electronic databases for publications reporting clinical and radiographic outcomes of periodontal intra-bony defects after regenerative therapy, divided by defect morphology. RESULTS The initial search resulted in 4487 papers, reduced to 143 after first and second screening. Fifteen of these publications were suitable for a fixed-effects meta-analysis. Initial defect depth was found to influence radiographic bone gain 12 months post-surgery, while narrower angles and increased number of walls influenced both radiographic bone gain and clinical attachment level (CAL) gain at 12 months. These associations seemed to occur irrespective of biomaterials used. Risk of bias ranged from low to high. CONCLUSION Deeper defects with narrower angles and increased number of walls exhibit improved CAL and radiographic bone gain at 12 months post-regenerative surgery. More data are needed about other aspects of defect morphology such as extension to buccal/lingual surfaces.

Abstract
BACKGROUND Aim of this systematic review (SR) of randomized controlled trials (RCTs) was to evaluate effect of different flap designs and graft materials for root coverage, in terms of aesthetics, patient satisfaction and self-reported morbidity (post-operative pain/discomfort). MATERIAL AND METHODS A comprehensive literature search was performed. A mixed-modelling approach to network meta-analysis was utilized to formulate direct and indirect comparisons among treatments for Root Coverage Esthetic Score (RES), with its individual components, and for subjective patient-reported satisfaction and post-operative pain/discomfort (visual analogue scale (VAS) of 100). RESULTS Twenty-six RCTs with a total of 867 treated patients (1708 recessions) were included. Coronally Advanced Flap (CAF) + Connective Tissue Graft (CTG) (0.74 (95% CI [0.24, 1.26], p = .005)), Tunnel (TUN) + CTG (0.84 (95% CI [0.15, 1.53]), p = .01) and CAF + Graft substitutes (GS) (0.55 (95% CI [0.006, 1.094], p = .04)) were significantly associated with higher RES than CAF. No significant difference between CAF + CTG and TUN + CTG was detected (0.09 (95% CI [-0.54, 0.72], p = .77)). Addition of CTG resulted in less natural tissue texture (-0.21 (95% CI [-0.34, -0.08]), p = .003) and gingival colour (-0.06 (95% CI [-0.12, -0.03], p = .03)) than CAF. CTG techniques were associated with increased morbidity. CONCLUSIONS Connective tissue graft procedures showed highest overall aesthetic performance for root coverage, although graft integration might impair soft tissue colour and appearance. Additionally, CTG-based techniques were also correlated with a greater patient satisfaction and morbidity.

Abstract
PURPOSE No information is available on the perception of the quality of care in patients treated for periodontitis. The purpose of this article was to assess how periodontitis-affected patients perceive the quality of periodontal treatment (PT) and to measure the factors which may influence it. MATERIALS AND METHODS 306 subjects who completed PT were invited to participate. Questionnaires and visual analogic scales (VAS) evaluating perception of quality of care, symptoms, and oral health related quality of life (OHRQoL) were handed out. Oral and periodontal indicators were collected before and after treatment. The impact of different factors on perception of quality was assessed with a regression model. RESULTS Quality evaluation was high yet unrelated for both patients and clinicians (p = 0.983). Quality was negatively influenced by the number of residual oral infections (p < 0.001), patient's age (p = 0.07) and presence of residual pain at completion of PT (p = 0.02). Professionalism, kindness of the staff and communication skills were the characteristics mostly appreciated. The OHRQoL was influenced by the number of residual teeth (p < 0.001), increasing age of patients (p = 0.08), number of residual infections (p < 0.01) and pain (p = 0.04). CONCLUSIONS Patients' quality perception appeared to be influenced by clinical and emotional aspects. Oral care providers should be aware of the impact of non-clinical factors in patients' appreciation of quality of treatment.

Abstract
BACKGROUND Periodontitis significantly increases the risk of diabetic complications. This clinical trial investigated the effects of periodontal therapy on cardiac function in patients with type 2 diabetes mellitus (T2DM) and periodontitis. MATERIALS AND METHODS Fifty-eight subjects with T2DM and periodontitis were randomly allocated to Treatment Group (n = 29) receiving non-surgical periodontal therapy, and Control Group (n = 29) having only oral hygiene instructions with delayed periodontal treatment until completion of this 6-month study. The left ventricle (LV) diastolic function was assessed by echocardiography with the tissue Doppler imaging index (E/e' ratio); and LV hypertrophy was evaluated by LV mass index (LVMI). Blood samples were collected for biochemical analysis. RESULTS The intention-to-treat analysis showed that periodontal treatment significantly reduced the E/e' ratio by 1.66 (95% CI: -2.64 to -0.68, p < .01), along with marked improvement of periodontal conditions (p < .05). LVMI was not altered at the 6-month follow-up. The serum levels of N-terminal pro-B type natriuretic peptide (NT-proBNP) as a cardiac stress biomarker, C-reactive protein and interleukin-6 decreased numerically without reaching statistical significance. CONCLUSION The present study provides the first evidence that non-surgical periodontal therapy may improve cardiac diastolic function in type 2 diabetic patients with periodontitis.

Abstract
AIM The aim of this study was to compare surgical treatment of periodontal intra-bony defects (IBD) with or without the adjunct of enamel matrix derivative (EMD) in terms of acute-phase responses in healthy patients. METHODS Thirty-eight periodontitis-affected subjects, one IDB each, were randomized to minimally invasive periodontal surgery (MIS) with or without EMD. Periodontal parameters were recorded at baseline and 6-months. Blood samples were collected at baseline, 1, 7 and 180 days after treatment. RESULTS At 24 hr, the group treated MIS with EMD showed lower values of C-reactive protein (CRP; p < .01) as no inflammatory perturbation was noticed. Conversely, MIS group resulted in an acute inflammatory response at 24 hr (p < .05) that regressed to its baseline values at day 7. The EMD group showed a higher number of cases without residual BOP or PPD ≥ 5mm 6 months after surgery (p < .05), and post-surgical gingival recession was lower (p < .05). CONCLUSIONS The adjunctive application of EMD during surgical treatment resulted in a minor increase in serum CRP 24-hr after surgery. These findings suggest a possible systemic anti-inflammatory effect of EMD. Within its limitations, this pilot trial confirmed better clinical periodontal outcomes in the EMD group. NCT03590093.

Abstract
BACKGROUND In Europe cardiovascular disease (CVD) is responsible for 3.9 million deaths (45% of deaths), being ischaemic heart disease, stroke, hypertension (leading to heart failure) the major cause of these CVD related deaths. Periodontitis is also a chronic non-communicable disease (NCD) with a high prevalence, being severe periodontitis, affecting 11.2% of the world's population, the sixth most common human disease. MATERIAL AND METHODS There is now a significant body of evidence to support independent associations between severe periodontitis and several NCDs, in particular CVD. In 2012 a joint workshop was held between the European Federation of Periodontology (EFP) and the American Academy of Periodontology to review the literature relating periodontitis and systemic diseases, including CVD. In the last five years important new scientific information has emerged providing important emerging evidence to support these associations RESULTS AND CONCLUSIONS: The present review reports the proceedings of the workshop jointly organised by the EFP and the World Heart Federation (WHF), which has updated the existing epidemiological evidence for significant associations between periodontitis and CVD, the mechanistic links and the impact of periodontal therapy on cardiovascular and surrogate outcomes. This review has also focused on the potential risk and complications of periodontal therapy in patients on anti thrombotic therapy and has made recommendations for dentists, physicians and for patients visiting both the dental and medical practices.

Abstract
AIM An acute phase response is induced after non-surgical periodontal treatment (SRP). The main aim of this study was to compare acute phase (24-hr) and medium-term (3-months) inflammation and clinical outcomes after SRP with or without application of enamel matrix derivative (EMD) in sites with probing pocket depth (PPD) ≥ 6 mm. METHODS Thirty-eight periodontitis-affected subjects were randomized to SRP or SRP + EMD. Periodontal parameters were recorded at baseline and 3 months. Serum samples were collected at baseline, 1 and 90 days after treatment. RESULTS Both treatments triggered an intense acute inflammation on day 1, which regressed to baseline values at 3 months. D-dimer and cystatin C levels did not show sharp increases in SRP + EMD group 24 hr after treatment, compared to SRP. Significant difference between groups was observed for D-dimer (p < 0.001). EMD application was also associated with better periodontal healing as shown by greater PPD reduction and clinical attachment level gain in sites with PPD ≥ 6 mm, and higher number of cases with no residual PPD ≥ 6 mm (p < 0.05) at 3 months. CONCLUSIONS EMD application after non-SRP resulted in lower fibrinolysis, and better periodontal healing of deep pockets. These initial observations warrant further investigations on the potential to modulate both local and systemic outcomes of non-SRP. NCT03544931.

Abstract
AIM To assess the clinical outcomes 9 years after the surgical treatment of single maxillary gingival recessions and identify predictors for long-term gingival margin stability. MATERIALS AND METHODS Twenty-five gingival recessions (Miller Class I and II) were randomly treated with Coronally Advanced Flap (CAF) plus Connective Tissue Graft (CTG) or CAF alone. Outcomes included complete root coverage (CRC), recession reduction (REC), keratinized tissue (KT) gain and dentin hypersensitivity, and were evaluated at 6 months, 1 and 9 years. Multilevel analysis was performed to identify predictors for long-term gingival margin stability. RESULTS Baseline gingival recession was 2.4 ± 0.8 mm and 2.4 ± 1.0 mm in the CAF + CTG and in the CAF-treated sites, respectively (p = 0.693). The chance to gain and preserve CRC over time is equal to 70% in the CAF + CTG group (Relative Risk [RR] = 1.70, 95% CI [0.84-3.45]; adjusted RR = 1.48, 95% CI [0.61-3.62]). Using the CTG, an increase in KT was recorded 9 years after the surgery (p = 0.019). An OR of 0.12 (p = 0.022) of not achieving CRC was observed in cases with non-carious cervical lesions (NCCL) compared to cases without NCCL. CONCLUSION Both treatment modalities demonstrated stability over time. Additional use of CTG provided a greater increase in KT. The presence of NCCL negatively affected CRC and REC.

The directional and non-directional associations of periodontitis with chronic kidney disease: A systematic review and meta-analysis of observational studies. J Periodontal Res 2018; 53:682-704.

Abstract
This systematic review aimed to assess the current evidence on the directional and non-directional associations of periodontitis with chronic kidney disease (CKD). Electronic search for observational studies on the association of periodontitis with CKD was performed in MEDLINE, EMBASE, PubMed, Open GREY and Cochrane library up to June 5, 2017. Two reviewers conducted study selection, data collection and assessment of methodological quality using the original and modified Newcastle-Ottawa Scale. Cohort, case-control and cross-sectional studies were included, which clearly defined periodontitis and CKD or reported acceptable clinical parameters of these 2 diseases in adults. Meta-analysis was employed to estimate the pooled odds ratio on the non-directional association and the incidence rate ratio (IRR) for the directional association. Among 2530 potential eligible articles, 47 were finally included. Most of them investigated a non-directional association of periodontitis with CKD, including 7 case-control studies and 38 cross-sectional studies; 24 studies had statistical analysis on the non-directional association and 75% of them reported significant results, which were supported further by the meta-analysis (random: odds ratio = 2.12, P < .001; χ2 = 25.74, I2 = 88.3%). None of the studies focused on the directional association of CKD (as the exposure) with periodontitis (as the outcome), whereas 2 retrospective cohort studies explored a directional association of periodontitis (as the exposure) with CKD (as the outcome) (random: IRR=2.10, P > .05; fixed: IRR=1.76, P < .05; χ2 = 4.65, I2 = 78.3%). Overall, the high heterogeneity of studies limits the significance of these results. There is substantial evidence on the non-directional association of periodontitis with CKD, while there are limited studies on the directional association. Well-designed prospective studies with longer follow-ups in representative communities are needed to clarify the directional association and enhance the quality of the evidence on this topic.

Abstract
BACKGROUND Diabetes and periodontitis are chronic non-communicable diseases independently associated with mortality and have a bidirectional relationship. AIMS To update the evidence for their epidemiological and mechanistic associations and re-examine the impact of effective periodontal therapy upon metabolic control (glycated haemoglobin, HbA1C). EPIDEMIOLOGY There is strong evidence that people with periodontitis have elevated risk for dysglycaemia and insulin resistance. Cohort studies among people with diabetes demonstrate significantly higher HbA1C levels in patients with periodontitis (versus periodontally healthy patients), but there are insufficient data among people with type 1 diabetes. Periodontitis is also associated with an increased risk of incident type 2 diabetes. MECHANISMS Mechanistic links between periodontitis and diabetes involve elevations in interleukin (IL)-1-β, tumour necrosis factor-α, IL-6, receptor activator of nuclear factor-kappa B ligand/osteoprotegerin ratio, oxidative stress and Toll-like receptor (TLR) 2/4 expression. INTERVENTIONS Periodontal therapy is safe and effective in people with diabetes, and it is associated with reductions in HbA1C of 0.27-0.48% after 3 months, although studies involving longer-term follow-up are inconclusive. CONCLUSIONS The European Federation of Periodontology (EFP) and the International Diabetes Federation (IDF) report consensus guidelines for physicians, oral healthcare professionals and patients to improve early diagnosis, prevention and comanagement of diabetes and periodontitis.

Abstract
There is strong evidence that genetic as well as environmental factors affect the development of periodontitis, and some suggestion that aggressive and chronic forms of the disease share the same genetic predisposition. This study addresses the hypothesis that there are both shared and unique genetic associations in these forms of periodontitis. A sample of 51 patients with aggressive disease, 57 patients with chronic disease, and 100 healthy controls was recruited for this study. Ten functional polymorphisms in 7 candidate genes were genotyped. The results show statistically significant (p ≤ 0.05) differences between genotype frequencies in aggressive and controls (IL-1B +3954 & IL-6 −174); chronic and controls (IL-6 −174 & VDR −1056); chronic and aggressive periodontitis (IL-1A −889); and periodontitis as a whole and controls (VDR −1056, TLR-4 399 & IL-6 −174). These results suggest that there are in fact both shared and unique genetic associations in aggressive and chronic periodontitis.

Abstract
BACGROUND On June 5th, 2015 at Europerio 8, a group of leading experts were gathered to discuss what has now been 20 years of documented evidence supporting the clinical use of enamel matrix derivative (EMD). Original experiments led by Lars Hammarström demonstrated that enamel matrix proteins could serve as key regenerative proteins capable of promoting periodontal regeneration including new cementum, with functionally oriented inserting new periodontal ligament fibres, and new alveolar bone formation. This pioneering work and vision by Lars Hammarström has paved the way to an enormous amount of publications related to its biological basis and clinical use. Twenty years later, it is clear that all these studies have greatly contributed to our understanding of how biologics can act as mediators for periodontal regeneration and have provided additional clinical means to support tissue regeneration of the periodontium. AIMS This review article aims to: (1) provide the biological background necessary to understand the rational for the use of EMD for periodontal regeneration, (2) present animal and human histological evidence of periodontal regeneration following EMD application, (3) provide clinically relevant indications for the use of EMD and (4) discuss future avenues of research including key early findings leading to the development of Osteogain, a new carrier system for EMD specifically developed with better protein adsorption to bone grafting materials.

Abstract
BACKGROUND The aim of this study was to assess soft-tissue re-growth following Fibre Retention Osseous Resective Surgery (FibReORS) or Osseous Resective Surgery (ORS) over a 12-month healing period. MATERIAL AND METHODS Thirty patients with chronic periodontitis showing persistent periodontal pockets at posterior natural teeth after cause-related therapy were enroled. Periodontal pockets were associated with infrabony defect ≤3 mm; 15 patients were randomly assigned to FibReORS (test group) and 15 to ORS (control group). Measurements were performed by a blind and calibrated examiner. Soft-tissue rebound after flap suture was monitored by changes in gingival recession at 1-, 3-, 6-, and 12- month follow-up. Multilevel analysis considering patient, site, and time levels was performed. RESULTS Greater osseous resection during surgery and higher post surgical gingival recession was observed in the ORS group. The mean amount of soft-tissue rebound following surgery was 2.5 mm for ORS-treated sites and 2.2 mm for FibReORS-treated sites. Approximately 90% of the coronal re-growth was detectable after 6 months for both procedures. The interaction between ORS and time of observation showed a higher soft-tissue rebound after 12 months (p = 0.0233) for ORS-treated sites. CONCLUSIONS Both procedures showed a similar coronal soft-tissue re-growth with a significant higher recession reduction for ORS-treated sites. Significant clinical stability of the gingival margin is obtained 6 months after surgery for both procedures.

Abstract
Body mass index (BMI) and obesity are associated with the prevalence, extent, and severity of periodontitis. This study investigated the predictive role of overweight/obesity on clinical response following non-surgical periodontal therapy in patients with severe periodontitis. Two hundred sixty adults received an intensive course of non-surgical periodontal therapy. Periodontal status at baseline and 2 months was based upon probing pocket depths (PPD), clinical attachment levels (CAL), and whole-mouth gingival bleeding (FMBS) as assessed by two calibrated examiners. Generalized estimating equations (GEE) were used to estimate the impact of BMI and overweight/obesity on periodontal treatment response while controlling for baseline status, age, smoking status (smoker or non-smoker), and full-mouth dental plaque score. BMI (continuous variable) and obesity (vs. normal weight) were associated with worse mean PPD (p < .005), percentage of PPD > 4 mm (p = .01), but not with FMBS (p > .05) or CAL (p > .05) at 2 months, independent of age, smoking status, or dental plaque levels. The magnitude of this association was similar to that of smoking, which was also linked to a worse clinical periodontal outcome (p < .01). BMI and obesity appear to be independent predictors of poor response following non-surgical periodontal therapy.

Abstract
Periodontal diseases constitute one of the major global oral health burdens, and periodontitis remains a major cause of tooth loss in adults worldwide. The World Health Organization recently reported that severe periodontitis exists in 5-20% of adult populations, and most children and adolescents exhibit signs of gingivitis. Likely reasons to account for these prevalent diseases include genetic, epigenetic, and environmental risk factors, as well as individual and socio-economic determinants. Currently, there are fundamental gaps in knowledge of such fundamental issues as the mechanisms of initiation and progression of periodontal diseases, which are undefined; inability to identify high-risk forms of gingivitis that progress to periodontitis; lack of evidence on how to prevent the diseases effectively; inability to detect disease activity and predict treatment efficacy; and limited information on the effects of integration of periodontal health as a part of the health care program designed to promote general health and prevent chronic diseases. In the present report, 12 basic, translational, and applied research areas have been proposed to address the issue of global periodontal health inequality. We believe that the oral health burden caused by periodontal diseases could be relieved significantly in the near future through an effective global collaboration.

Abstract
The genetic power of a Brazilian three-generation family with generalized aggressive periodontitis (GAgP) has been reported. The empirical logarithms of the odds (LOD) score thresholds for genetic linkage analysis of complex diseases proposed by Haines rely on confirmation from independent datasets. This study estimated the power of another large Brazilian family with GAgP for future linkage analysis. The three-generation family was seen at the Dental School of the Federal University of Bahia. Following the previously described methodology, full-mouth periodontal probing at 6 sites/tooth was performed in all 19 family members. Six out of 12 siblings were affected with GAgP. All affected family members were non-smokers and did not present diabetes or any other systemic condition or consanguinity. A parametric simulation (?=0) was performed on 100 replicates using the statistical software SLINK for linkage analysis. There was maximum expected LOD scores of 3.75 and 3.45 at penetrance rate F=0.98, and both studied phenocopy rates P=0.0 and P=0.02, respectively. The power of the study increased with the increase of the adopted penetrance rates in both studied phenocopy rates. The studied Brazilian three-generation family showed statistical power for future genetic linkage analysis of candidate genes to GAgP.

Abstract
Aggressive periodontitis is a multifactorial disease with strong familial aggregation. Genetic linkage analysis is a method to localize causative or predisposing genes along the chromosome, thus helping to unravel important pathogenic pathways. Prior to applying this method, however, it is essential to estimate the power of the study design. The aim of this study was to estimate the power of a large Brazilian family with generalized aggressive periodontitis (GAgP) for future linkage analysis. A three-generation family was seen at the Dental School of the Federal University of Bahia. A full-mouth periodontal probing at 6 sites/tooth was performed in all 23 family members. Five out of 10 siblings were affected with GAgP. A parametric simulation (? = 0) was performed on 100 replicates using the statistical software SLINK for linkage analysis. The linkage LOD score criteria for complex diseases described by Haines was adopted. There was maximum expected LOD scores of 3.56 and 3.48 at penetrance rate F = 0.98, and both studied phenocopy rates p=0.0 and p=0.02, respectively. The analyzed family showed statistical power for future genetic linkage analysis of candidate genes to GAgP.

Abstract
AIM This prospective randomized-controlled clinical trial compared the gingival blood flow responses following simplified papilla preservation (test) versus modified Widman flap (control). MATERIALS AND METHODS Twenty contra-lateral upper sites with pocket depth > or = 5 mm after initial treatment in 10 chronic periodontitis patients were randomly assigned to either test or control treatment, using a split-mouth design. Laser Doppler flowmetry recordings were performed pre-operatively, following anaesthesia, immediately post-operatively and on days 1, 2, 3, 4, 7, 15, 30 and 60, at nine selected sites per flap. RESULTS Significant ischaemia was observed at all sites following anaesthesia and immediately post-operatively. At the mucosal flap basis, a peak hyperaemic response was observed on day 1, which tended to resolve by day 4 at the test sites, but persisted until day 7 at the control sites. The buccal and palatal papillae blood perfusion presented the maximum increase on day 7 in both groups and returned to baseline by day 15. Both surgical modalities yielded significant pocket depth reduction, recession increase and clinical attachment gain. CONCLUSIONS Periodontal access flaps represent an ischaemia-reperfusion flap model. The simplified papilla preservation flap may be associated with faster recovery of the gingival blood flow post-operatively compared with the modified Widman flap.

Abstract
AIM To investigate the pattern of gingival blood flow changes following periodontal access flap surgery by laser Doppler flowmetry (LDF). MATERIAL AND METHODS Fourteen patients with chronic periodontitis presenting upper anterior sites with pocket depth >or=5 mm after initial treatment were included in the study. Periodontal access flap surgery was performed on the experimental areas and LDF recordings were taken at baseline, following anaesthesia, immediately postoperatively and on days 1, 2, 3, 4, 7, 15, 30 and 60 of healing, at nine predetermined sites per flap. RESULTS Significant ischaemia was observed at all flap sites following anaesthesia and immediately postoperatively. At the alveolar mucosal sites, a peak increase of the gingival blood flow was observed on postoperative day 1 (p<0.001), which persisted until day 7 (p=0.012) and resolved by day 15. The mucosal sites close to the flap periphery presented higher blood perfusion compared with the sites located centrally in the flap. The microcirculatory perfusion of the buccal and palatal papillae was maximum on postoperative day 7 (p=0.013 and <0.001, respectively) and returned to baseline by day 15. CONCLUSION Topographically distinct areas of the periodontal access flap consistently present different patterns of microvascular blood flow alterations during the wound-healing period.

Abstract
BACKGROUND/AIM Tobacco use reduces the effect of non-surgical periodontal therapy. Host-modulation with low-dose doxycycline (LDD) might favour repair and promote an improved treatment response. The aim of this study was to investigate the effect of LDD in smokers on non-surgical periodontal therapy. MATERIAL AND METHODS This was a parallel arm, randomized, identical placebo-controlled trial with masking of examiner, care-giver, participant and statistician and 6 months of follow-up. Patients received non-surgical therapy and 3 months of test or control drug. Statistical analysis used both conventional methods and multilevel modelling. RESULTS Eighteen control and 16 test patients completed the study. The velocity of change was statistically greater for the test group for clinical attachment level -0.19 mm/month (95% CI=-0.34, 0.04; p=0.012) and probing depth 0.30 mm/month (95% CI=-0.42, -0.17; p<0.001). However, no differences were observed for absolute change in clinical or biochemical markers at 6 months. CONCLUSIONS This study does not provide evidence of a benefit of using LDD as an adjunct to non-surgical periodontal therapy in smokers.

Abstract
OBJECTIVE To describe the periodontal tissues formed following guided tissue regeneration (GTR) therapy of intra-bony defects (IBD). METHODS Eight adult Macaca fascicularis monkeys were used. Proximal IBD were created at the mandibular second pre-molars and second molars. After 3 months, GTR surgery was performed. The animals were euthanized at 6 months and 2 years after surgery. Block biopsies were harvested, and prepared for histological analysis. RESULTS At 6 months the defect had healed with new cementum (NC), periodontal ligament (PDL) and bone. The NC seemed to be firmly anchored to the dentin. Supra-crestally, the NC consisted of a 10 microm thick layer of acellular extrinsic fibre cementum (AEFC). Sub-crestally, the NC was considerably thicker and consisted of an inner layer of AEFC and an outer thicker layer of cellular mixed fibre cementum (CMFC). The extrinsic fibre density amounted to about 10 fibres per 100 microm. The PDL was wider than the pristine PDL and widened in coronal direction. After 2 years of healing, the thickness of the NC in the sub-crestal compartment had increased by about 20 microm and the fibre density had increased by about 50%. CONCLUSION After 2 years of healing the structure of the regenerated tissues resembled that of pristine periodontal tissues.

Abstract
To evaluate the osteoinductive potential of deproteinized bovine bone mineral (DBBM) and an enamel matrix derivative (EMD) in the muscle of rats. Sixteen rats were used in this study. The animals were divided in three groups. Group A: a pouch was created in one of the pectoralis profundis muscles of the thorax of the rats and DBBM particles (Bio-Oss) were placed into the pouch. Healing: 60 days. Group B: a small pouch was created on both pectoralis profundis muscles at each side of the thorax midline. In one side, a mixture of EMD (Emdogain) mixed with DBBM was placed into one of the pouches, whereas in the contralateral side of the thorax the pouch was implanted with DBBM mixed with the propylene glycol alginate (PGA--carrier for enamel matrix proteins of EMD). Healing: 60 days. Group C: the same procedure as group B, but with a healing period of 120 days. Qualitative histological analysis of the results was performed. At 60 days, the histological appearance of the DBBM particles implanted alone was similar to that of the particles implanted together with EMD or PGA at both 60 and 120 days. The DBBM particles were encapsulated into a connective tissue stroma and an inflammatory infiltrate. At 120 days, the DBBM particles implanted together with EMD or PGA exhibited the presence of resorption lacunae in some cases. Intramuscular bone formation was not encountered in any group. The implantation of DBBM particles alone, combined with EMD or its carrier (PGA) failed to exhibit extraskeletal, bone-inductive properties.
