Background: The recently published clinical practice guideline (CPG) for the treatment of periodontitis in stages I-III provided evidence-based recommendations for the treatment of periodontitis patients, defined according to the 2018 classification. Stage IV periodontitis shares the severity and complexity characteristics of stage III periodontitis, but includes the anatomical and functional sequelae of tooth and periodontal attachment loss (tooth flaring and drifting, bite collapse, etc.), which require additional interventions following completion of active periodontal therapy. Aim: To develop an S3 Level CPG for the treatment of stage IV periodontitis, focusing on the implementation of inter-disciplinary treatment approaches required to treat/rehabilitate patients following associated sequelae and tooth loss. Materials and Methods: This S3 Level CPG was developed by the European Federation of Periodontology (EFP), following methodological guidance from the Association of Scientific Medical Societies in Germany and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) process. A rigorous and transparent process included synthesis of relevant research in 13 specifically commissioned systematic reviews, evaluation of the quality and strength of evidence, the formulation of specific recommendations and a structured consensus process with leading experts and a broad base of stakeholders. Results: The S3 Level CPG for the treatment of stage IV periodontitis culminated in recommendations for different interventions, including orthodontic tooth movement, EFP workshop participants and methodological consultant are listed in Appendix.
Aim: To evaluate the safety and efficacy of autologous periodontal ligament-derived mesenchymal stem cells (PDL-MSCs) embedded in a xenogeneic bone substitute (XBS) for the regenerative treatment of intra-bony periodontal defects. Material and Methods: This quasi-randomized controlled pilot phase II clinical trial included patients requiring a tooth extraction and presence of one intra-bony lesion (1-2 walls). Patients were allocated to either the experimental (XBS + 10 × 10 6 PDL-MSCs/100 mg) or the control group (XBS). Clinical and radiographical parameters were recorded at baseline, 6, 9 and 12 months. The presence of adverse events was also evaluated. Chi-square, Student's t test, Mann-Whitney U, repeated-measures ANOVA and regression models were used. Results: Twenty patients were included. No serious adverse events were reported. Patients in the experimental group (n = 9) showed greater clinical attachment level (CAL) gain (1.44, standard deviation [SD] = 1.87) and probing pocket depth (PPD) reduction (2.33, SD = 1.32) than the control group (n = 10; CAL gain = 0.88, SD = 1.68, and PPD reduction = 2.10, SD = 2.46), without statistically significant differences. Conclusion: The application of PDL-MSCs to XBS for the treatment of one-to two-wall intra-bony lesions was safe and resulted in low postoperative morbidity and appropriate healing, although its additional benefit, when compared with the XBS alone, was not demonstrated.
Background and Aims: The scope of this working group was to review: (1) the effect of professional mechanical plaque removal (PMPR) on secondary prevention of periodontitis; (2) the occurrence of gingival recessions and non-carious cer- Key words: dentine hypersensitivity; intra-oral halitosis; non-carious cervical lesion; oral malodour; professional plaque removal; supportive periodontal therapy; traumatic tooth brushing vical lesions (NCCL) secondary to traumatic tooth brushing; (3) the management of hypersensitivity, through professionally and self administered agents and (4) the management of oral malodour, through mechanical and/or chemical agents. Results and Conclusions: Patients undergoing supportive periodontal therapy including PMPR showed mean tooth loss rates of 0.15 AE 0.14 teeth/year for 5-year follow-up and 0.09 AE 0.08 teeth/year (corresponding to a mean number of teeth lost ranging between 1.1 and 1.3) for 12-14 year follow-up. There is no direct evidence to confirm tooth brushing as the sole factor causing gingival recession or NCCLs. Similarly, there is no conclusive evidence from intervention studies regarding the impact of manual versus powered toothbrushes on development of gingival recession or NCCLs, or on the treatment of gingival recessions. Local and patient-related factors can be highly relevant in the development and progression of these lesions. Two modes of action are used in the treatment of dentine hypersensitivity: dentine tubule occlusion and/or modification or blocking of pulpal nerve response. Dentifrices containing arginine, calcium sodium phosphosilicate, stannous fluoride and strontium have shown an effect on pain reduction. Similarly, professionally applied prophylaxis pastes containing arginine and calcium sodium phosphosilicate have shown efficacy. There is currently evidence from short-term studies that tongue cleaning has an effect in reducing intra-oral halitosis caused by tongue coating. Similarly, mouthrinses and dentifrices with active ingredients based on Chlorhexidine, Cetylpyridinium chloride and Zinc combinations have a significant beneficial effect.

Objectives:The aim of this study was to comprehensively assess the literature in terms of the effect of peri-implant mucosal thickness on esthetic outcomes and the efficacy of soft tissue augmentation procedures to increase the mucosal thickness with autogenous grafts or soft tissue substitutes.Material and methods: Two systematic reviews (SR) were performed prior to the consensus meeting to assess the following questions. Review 1, focused question: In systemically healthy patients with an implant-supported fixed prosthesis, what is the influence of thin as compared to thick peri-implant mucosa on esthetic outcomes? Review 2, focused question 1: In systemically healthy humans with at least one dental implant (immediate or staged implant), what is the efficacy of connective tissue graft (CTG), as compared to absence of a soft tissue grafting procedure, in terms of gain inThis is an open access article under the terms of the Creative Commons Attribution-NonCommercial License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited and is not used for commercial purposes.
