显微牙周外科技术在翻瓣术中的临床疗效分析

Clinical evaluation of periodontal flap surgery with the use of dental microscope

目的:探讨显微牙周外科技术对翻瓣术临床疗效的影响。方法:选取30例慢性牙周炎患者,随机均分为2组,实验组在口腔显微镜辅助下、采用微创器械行牙周翻瓣术;对照组在普通视野下行常规翻瓣术。用统计学方法比较术后1、3、7 d的VAS疼痛指数,及基线、术后3、6个月的牙周临床指标。结果:实验组在术后1 d及3 d的VAS疼痛指数显著低于对照组(P=0.017和0.004);术后3、6个月时,实验组牙周探诊深度的下降趋势显著大于对照组(P=0.010和0.047)。结论:显微牙周外科技术比常规翻瓣术更能够显著地改善牙周袋深度,牙龈退缩和临床附着丧失的水平更低,有效减轻疼痛感觉。

Objective：To evaluate the effects of periodontal flap surgery with the aid of microscope in the treatment of patients with chronic periodontitis（CP）.Methods：30 patients with CP included in the study were randomly divided into 2 groups.Patients in the experiment group received periodontal flap surgery with the aid of microscope,while those in the control group received the routine flap surgery.The VAS pain scores were compared 1 ,3 and 7 days after surgery.The periodontal parameters were compared 3 and 6 months after surgery between 2 groups.Results：The VAS pain score in the experiment group was significantly lower than that in the control group 1 and 3 days （P =0.01 7 and 0.004）after surgery;the periodontal probing depth in the experiment group was significantly lower than that in the control group 3 and 6 months （P =0.01 0 and 0.047）after surgery.Conclusion：The periodontal probing depth,gin-gival recession and clinical attachment level can be improved and the pain can be reduced in the treatment of CP patients with the aid of microscope in the periodontal flap surgery.
