Locally Delivered Atorvastatin & Rosuvastatin for Treatment of Furcation Defects in Chronic Periodontitis

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 1.2% ATV gel as a local drug delivery and redelivery system as an adjunct to scaling and root planing (SRP) for the treatment of degree II furcation defects.

Methods: Ninety patients with mandibular buccal class II furcation defects were randomly allocated into three treatment groups: SRP plus placebo gel (group 1), SRP plus 1.2% RSV gel (group 2) and 1.2% ATV gel (group3). Clinical and radiographic parameters were recorded at baseline then after 6 months. The gels were redelivered at the respective sites at this 6 month appointment. Then again all clinical and radiographic parameters were recorded after 3 months. (9 months from baseline)

Inclusion criteria

• Systemically healthy patients with mandibular class II furcation defects and asymptomatic endodontically vital mandibular molars with radiolucency in furcation area with PD ≥ 5mm and horizontal PD ≥ 3mm and with no history of antibiotic or any periodontal therapy in past 6 months were included in the study

Exclusion criteria

• Subjects with any known systemic disease, allergic to statins, on systemic statin therapy, alcoholics, tobacco users, pregnant or lactating women
