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。

Abstract: Objective: To analyze the clinical efficacy of photodynamic therapy (PDT) assisted regenerative surgery in the treatment of degree Ⅱ root 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 ofdegree Ⅱ furcation root involvement on the buccal side of maxillary molars.
