摘　　要：目的:分析光动力疗法(photodynamic therapy,PDT)辅助再生性手术治疗上颌磨牙颊侧Ⅱ°根分叉病变的临床疗效。方法:将52颗患牙随机分为单纯手术治疗组(对照组)和PDT辅助手术治疗组(试验组),每组26颗,两组患牙再生性手术中均使用海奥口腔修复膜和Bio-Oss骨粉。对比两组患牙术前、术后6个月的牙周垂直和水平探诊深度、附着丧失、出血指数,以及根分叉病变区域垂直骨缺损和水平骨缺损的变化。结果:术后6个月试验组与对照组比较,出血指数变化量无明显差异(P>0.05),其余各项指标的变化量高于对照组(P<0.05)。结论:应用PDT辅助再生性手术治疗上颌磨牙颊侧Ⅱ°根分叉病变,可以提高临床治疗效果。Objective:To analyze the clinical efficacy of photodynamic therapy(PDT)assisted regenerative surgery in the treatment of degreeⅡroot furcation involvement on the buccal side of maxillary molars.Methods:Fifty-two teeth were randomly divided into simple surgical treatment group(control group)and PDT assisted surgical treatment group(experimental group),with 26 teeth in each group.Both groups were treated with Heal-All oral repair membrane and Bio-Oss bone particles.Changes of periodontal probing depth,horizontal probing depth,clinical attachment loss,bleeding index,and vertical and horizontal bone loss in the root furcation involvement area were compared between two groups before and 6 months after surgery.Results:Six months after operation,except for the bleeding index(P>0.05),the changes of other indexes in the experimental group were higher than thosein the control group(P<0.05).Conclusion:The application of PDT assisted regenerative surgery can improve the clinical treatment effect ofdegreeⅡfurcation root involvement on the buccal side of maxillary molars.
