OBJECTIVE: The aim of this systematic review is to assess the efficacy of locally delivered statins used in adjunct to scaling and root planing (SRP), compared with SRP alone.
MATERIALS AND METHODS: An electronic and hand search was carried out up to April 2020. Only randomized controlled trials (RCTs) were included. Clinical attachment level gain (CALgain) and probing depth reduction (PDred), modified sulcular bleeding index reduction (mSBIred), and intrabony defect reduction (IBDred) were the investigated outcomes. Meta-analysis was performed, and the power of the meta-analytic findings was determined by trial sequential analysis (TSA). Studies were also sub-grouped based on the type of statin used. Statistical heterogeneity and publication bias were assessed.
RESULTS: Twenty RCTs were included (1212 patients, 1289 defects). An overall statistically significant effect size in favor of statins for CALgain and PDred was found. As opposed to atorvastatin and rosuvastatin, simvastatin did not reach statistical significance for these outcomes, as shown by the sub-group analysis.
CONCLUSIONS: Within the limits of the available studies, the local administration of statins (in particular, atorvastatin and rosuvastatin) in adjunct to SRP may result in additional significant improvement in terms of CALgain and PDred compared with SRP alone. The high heterogeneity of data and the high risk of bias found, however, impose caution. No approved preparations, moreover, exist, and further well-designed RCTs from independent research centers are needed to confirm the beneficial effects of the different statins and their mutual differences in the non-surgical periodontal treatment.Free PDF Download
