Aim To systemically review the available evidence on the clinical performance of osseous resective surgery (ORS) in the treatment of residual periodontal defects in terms of pocket elimination and biological costs in patients with chronic periodontitis. Materials and methods Three databases (PubMed, EMBASE and Cochrane) were searched up to January 2019. Clinical trials with a follow-up duration of at least 12 months after ORS with or without fibre retention technique were included. Quantitative synthesis was conducted with random-effect meta-analysis. Results Overall, 1,765 studies were retrieved, of which 53 full-text articles were screened by two reviewers. Finally, a total of three RCTs were included in the meta-analysis. Random-effect meta-analysis showed a weighted mean percentage of pocket elimination (final PD ≤ 4 mm) at 12 months of 98.3% (95% CI: 96.8; 99.7) with I2 of 26%. The weighted mean amount of resected bone was 0.87 mm (95% CI: 0.49; 1.25), and the weighted mean increase in gingival recession was 2.13 mm (95% CI: 1.49; 2.78) at 12 months. Conclusions ORS represents an effective surgical approach for the elimination of residual periodontal pockets in the short to medium term. Additional randomized controlled clinical trials with data on pocket elimination are warranted.

AIM To analyse the efficacy of non-surgical therapy (NST) in terms of pocket closure (PC) and changes in percentage and number of pockets. MATERIALS AND METHODS Three databases (PubMed, EMBASE, and Scopus) were searched up to January 2020. Prospective studies with a minimum follow-up of 12 months and presenting data in terms of PC or number or percentage of pocket depths (PDs) before and after NST on systemically healthy patients were included. Random-effect meta-analyses were performed. RESULTS After screening 4610 titles and abstracts, 27 studies were included. Of these, 63.9% of PC was reported by one study. The percentage of PDs ≤3 mm changed from 39.06% to 64.11% with a weighted mean difference (WMD) of 26.14% (p
