Locally Delivered Metformin & Rosuvastatin for Treatment of Intrabony Defects in Chronic Periodontitis

Locally Delivered Metformin & Rosuvastatin for Treatment of Intrabony Defects in Chronic Periodontitis

Comparative Evaluation of Locally Delivered 1% Metformin and 1.2% Rosuvastatin Gel in Treatment of Intrabony Defects in Chronic Periodontitis Subjects: A Randomized Controlled Clinical Trial

Metformin (MF), a biguanide group of anti-diabetic drug has been shown to enhance osteoblasts differentiation and inhibit osteoclast differentiation in vitro, thus may exhibit a favourable effect on alveolar bone. Statins are one of the lipid lowering drugs that help in reducing cholesterol levels in the body by specifically inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase; which is a rate limiting enzyme for cholesterol synthesis. Rosuvastatin (RSV) have shown to have bone stimulatory and anti-inflammatory effects.Statins are one of the lipid lowering drugs that help in reducing cholesterol levels in the body by specifically inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase; which is a rate limiting enzyme for cholesterol synthesis. Rosuvastatin (RSV) and atorvastatin (ATV) have shown to have bone stimulatory and anti-inflammatory effects.. The present study aims to explore the efficacy of 1.2% RSV and 1MF gel as a local drug delivery and redelivery system as an adjunct to scaling and root planing (SRP) for the treatment of intrabony defects.

The present study aims to explore the efficacy of 1.2% RSV and 1MF gel as a local drug delivery and redelivery system as an adjunct to scaling and root planing (SRP) for the treatment of intrabony defects. Methods: Ninety patients with intrabony defects were randomly allocated into three treatment groups: SRP plus placebo gel (group 1), SRP plus 1.2% RSV gel (group 2) and 1% MF gel (group3). Clinical and radiographic parameters were recorded at baseline then after 6 months. The gels were delivered at the respective sites at baseline . Then again all clinical and radiographic parameters were recorded after 6 months and 12 months.

Inclusion Criteria: - All the subjects were systemically healthy subjects with sites having CAL ≥ 3 mm, PPD ≥ 5 mm, vertical bone loss ≥ 3 mm on intraoral periapical radiographs (IOPA) and subjects with no history of periodontal intervention in the last 6 months. Exclusion Criteria: patients with systemic diseases like cardiovascular disease diabetes or HIV infection or on medications like corticosteroids which may impede the healing in periodontal tissues. pregnant/lactating females tobacco users alcoholics patients with unsatisfactory oral hygiene (plaque index greater than 1.5) teeth having gingival recession, caries involving pulp, intrabony defect present interproximally, grade 2/3 mobility Furthermore, patients allergic to Metformin and rosuvastatin or those taking Metformin and rosuvastatin systemically were excluded. -
