BACKGROUND: The aim of this study is to investigate efficacy of metformin (MF) 1% gel as an adjunct to scaling and root planing (SRP) in the treatment of moderate and severe chronic periodontitis (CP).
METHODS: Seventy patients were categorized into two treatment groups: 1) SRP plus 1% MF and 2) SRP plus placebo. Clinical parameters were recorded at baseline and 3, 6, and 9 months. They included plaque index (PI), modified sulcus bleeding index (mSBI), probing depth (PD), and clinical attachment level (CAL). Radiologic assessment of intrabony defects (IBDs) and percentage defect depth reduction (DDR%) was done at baseline and 6- and 9-month intervals using computer-aided software. PD, CAL, and DDR% were evaluated in two subgroups in both the placebo and MF group: 1) initial PD of 5 to 7 mm and 2) initial PD of >7 mm.
RESULTS: Mean PD reduction and mean CAL gain was found to be greater in the MF group than the placebo group at all visits. Clinical parameters (PD, CAL) in both subgroups, with initial PDs of 5 to 7 and >7 mm, showed significant improvement in the 1% MF group compared with the placebo group. A significantly greater mean DDR% was found in the MF group than the placebo group at 6 and 9 months in both subgroups, 5 to 7 and >7 mm of initial PD.
CONCLUSION: There was a greater decrease in PD and more CAL gain with significant IBD depth reduction at sites treated with SRP plus locally delivered MF in patients with CP in both initial PD = 5 to 7 and >7 mm subgroups compared with placebo.
