The present randomized controlled clinical study was designed to investigate the effect of in situ application of 1.2 mg Simvastatin (SV) gel in the surgical management of Intrabony defects in chronic periodontitis patients.
20 patients contributing 40 sites were categorized into two treatment groups: Open flap debridement plus 1.2 mg SV gel (Group 1) and Open flap debridement plus Placebo gel (Group 2). Gingival index (GI), Plaque index (PI), Pocket depth (PD) and clinical attachment level (CAL) were recorded at baseline, 3 months, 6 months and 9 months. At baseline and at the end of 6 and 9 months Radiographic evaluation of Intrabony defect fill was done using Image j software.
Significant reduction of GI, PD and gain in CAL was observed at the end of 9 months in both groups. Amount of bone fill and percentage of original defect fill in Group 1 was statistically highly significant than Group 2 at the end of 6 and 9 months.
Higher amount of decrease in GI and PD along with more amount of CAL gain was observed in treatment group than control group. Radiological assessment confirmed that significant intrabony defect fill and percentage fill of original defect in treatment group than controlled group.
本随机对照临床研究旨在调查在慢性牙周炎患者骨内缺损的外科治疗中局部应用1.2毫克辛伐他汀(SV)凝胶的效果。
20名患者共40个部位被分为两个治疗组:开放性翻瓣清创术加1.2毫克SV凝胶(第1组)和开放性翻瓣清创术加安慰剂凝胶(第2组)。在基线、3个月、6个月和9个月时记录牙龈指数(GI)、菌斑指数(PI)、牙周袋深度(PD)和临床附着水平(CAL)。在基线以及6个月和9个月结束时,使用Image j软件对骨内缺损填充情况进行影像学评估。
两组在9个月末均观察到GI、PD显著降低以及CAL增加。在6个月和9个月末,第1组的骨填充量和原始缺损填充百分比在统计学上显著高于第2组。
与对照组相比,治疗组的GI和PD下降幅度更大,CAL增加量更多。影像学评估证实,治疗组的骨内缺损填充量和原始缺损填充百分比显著高于对照组。
