Comparative evaluation of subgingivally delivered 1.2% rosuvastatin and 1% metformin gel in treatment of intrabony defects in chronic periodontitis: A randomized controlled clinical trial

Abstract Background The aim of this study is to explore and compare the clinical efficacy of locally delivered 1.2% Rosuvastatin (RSV) and 1% Metformin (MF) gel as an adjunct to scaling and root planning (SRP) in the treatment of intrabony defects in chronic periodontitis patients. Methods A total of 90 volunteers were randomly assigned to three treatment groups; 1) SRP plus placebo gel; 2) SRP plus 1.2% RSV gel; 3) SRP plus 1% MF gel. Clinical parameters like modified sulcus bleeding index (mSBI), plaque index (PI), pocket probing depth (PD) and clinical attachment level (CAL) were recorded at baseline, 6 and 12 months and the radiologic assessment of bone defect fill was performed at 6 and 12 months. Results mSBI, BP, PD, and CAL were improved in all the groups, however mean reductions in PD, CAL gain, and percentage of bone fill was found to be higher in RSV and MF groups than placebo group at all visits. Conclusion Adjunctive use of locally delivered 1.2% RSV and 1% MF gel stimulates a significant PD reduction, CAL gains and improved bone fill when compared with placebo gel. Results were significantly better with the use of 1.2% RSV gel than 1% MF gel.
