摘要
Abstract Aim To evaluate the changes in periodontal parameters (reduction in probing pocket depth [PPD], gain in clinical attachment level [CAL] and reduction in full‐mouth bleeding on probing [BoP]) after subgingival instrumentation of periodontal pockets at different time points in systemically healthy patients suffering from periodontitis. Materials and Methods Four databases were searched for RCTs that carried out subgingival instrumentation in periodontal pockets and evaluated PPD at a minimum of two consecutive time points other than baseline. The analysis was conducted for both all pocket depths and stratified for initially shallow (4–5 mm) and deep (≥6 mm) pockets and data were extracted for various time points, 1–2, 3–4 and 5–6 months. Weighted mean effects (WMEs) were calculated with 95% confidence interval (CI) and predictive intervals were calculated. Results Twenty‐nine RCTs were identified, and all of them were included in the meta‐analysis. The results showed that for both shallow and deep pockets there was a small though clinically meaningful change between 1‐ to 2‐month and 3‐ to 4‐month time points and between these and 5–6 months. Conclusions In systemically healthy patients, the greater part of reduction in PPD and gain in CAL occurs within the first 1–2 months after subgingival instrumentation. However, additional benefits in terms of pocket depth reduction occur beyond these early time points.
