Brief Summary

BACKGROUND: Chronic periodontitis (CP) is an inflammatory condition affecting tooth supporting tissues and alveolar bone that surround the tooth leading to formation of deepend gingival sulcus that is highly prone to pathologic changes, ultimately bone resorption and tooth loss. In the literature, several pharmacologic agents have been administration via local delivery route, directly into diseased sites affirming greater improvement in periodontal status. Therefore, present study was conducted to determine the clinical effectiveness of subgingivally delivered 1.2% Rosuvastatin gel incorporated into an methylcellulose vehicle for its controlled release into intrabony defect sites in adjunct to scaling and root planing for treatment of chronic periodontitis patients.

MATERIAL AND METHODS: Sixty five patients were categorized into two treatment groups: group I -SRP plus RSV, 1.2 mg and group II -SRP plus placebo. Clinical parameters included modified sulcus bleeding index (mSBI), probing depth (PD), and clinical attachment level (CAL), were recorded at baseline before SRP and at 1, 3, 4, and 6 months. Radiologic assessment of intrabony defect (IBD) fill was analysed at baseline and after 6months using computer-aided software.

Detailed Description

Rosuvastatin (RSV) is one of new synthetic, second-generation, sulfur-containing, hydrophilic statin, a highly efficient competitive inhibitors of HMG CoA Reductase having important role in reducing serum cholesterol concentrations and lowers the risk of cardiovascular disease. It has potent anti-inflammatory effects, mediated via vascular endothelium derived nitric oxide (eNO) that inhibits P selectin synthesis by endothelial cells. This protective action is evidenced by reduced levels of high-sensitivity C-Reactive Protein (hs-CRP) , a clinical marker of inflammation produced in response to proinflammatory cytokines such as interleukin-6 (IL-6), therefore it contributes to the prevention and remission of inflammatory diseases. Recently, an in-vivo study demonstrated that RSV promotes osteoblast differentiation, by regulating the expression of solute carrier (Slco1a1), which may constitute the transport system for RSV across the cell membrane in mature osteoblasts.
