Abstract

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.

Key words: photodynamic therapy, degree Ⅱ furcation involvement, regenerative surgery
