Title: Comparative evaluation of subgingivally-delivered 1% metformin and Aloe vera gel in the treatment of intrabony defects in chronic periodontitis patients: A randomized, controlled clinical trial. Author: Kurian IG, Dileep P, Ipshita S, Pradeep AR. Journal: J Investig Clin Dent; 2018 Aug; 9(3):e12324. PubMed ID: 29981205. Abstract: AIM: The aim of the current study was to explore the effectiveness of locally-delivered 1% metformin (MtF) and Aloe vera (AV) 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: (a) SRP + placebo gel; (b) SRP + 1% MtF gel; and (c) SRP + AV gel. Clinical parameters, including gingival index (GI), bleeding on probing (BoP), pocket probing depth (PPD), and clinical attachment level (CAL), were recorded at baseline, and 6 and 12 months. The radiological assessment of bone defect fill was done at 6 and 12 months. RESULTS: GI, BoP, PPD, and CAL improved in all the groups; however, the mean PPD reduction, CAL gain, and percentage of bone fill was found to be greater in the MtF and AV groups than the placebo group at all visits. CONCLUSION: Local delivery of 1% MtF and AV gel stimulates a significant PPD reduction, CAL gain, and improved bone fill and regeneration when compared with placebo gel. Results were significantly better with the use of 1% MtF gel than AV gel.[Abstract] [Full Text] [Related] [New Search]
