摘　　要：目的观察光动力疗法联合龈下刮治和根面平整术治疗慢性牙周炎的临床效果。方法选择中、重度慢性牙周炎患者30例,随机分为3组,每组10人。A组:单纯龈下刮治和根面平整术治疗;B组:龈下刮治和根面平整术治疗后即刻行光动力疗法;C组:龈下刮治和根面平整术治疗后1周行光动力疗法。治疗前、龈下刮治和根面平整术治疗后6周、12周时分别记录牙周袋探诊深度及探诊出血的阳性牙位点,并进行统计学分析。结果龈下刮治和根面平整术后6周和12周结果显示,3组牙周袋探诊深度和探诊出血情况较术前均有改善(P<0.05)。B组和C组的牙周袋探诊深度和探诊出血情况改善效果均优于A组(P<0.05);B组与C组间差异无统计学意义(P>0.05)。结论对中、重度慢性牙周炎患者应用光动力疗法联合龈下刮治和根面平整术治疗,较单独使用龈下刮治和根面平整术治疗效果更佳。光动力疗法可作为新的辅助治疗手段用于牙周病的治疗。Objective To evaluate the effect of the treatment of chronic periodontitis by photodynamic therapy combined with scaling and root planing. Methods Thirty patients with moderate and severe chronic periodontitis were randomly divided into three groups of 10. Group A received SRP alone , group B received PDT immediately after SRP , group C received PDT one week after SRP . Probing depth（PD） and bleeding on probing（BOP） were recorded at baseline, 6 and 12 weeks after SRP. The results were statistically analyzed. Result Clinical parameters of all the three groups improved significantly after therapy,but more reduction of PD and BOP were observed in group B and C 6 and 12 weeks after SRP（ P 〈 0. 05 ）, and there was no significant difference between group B and C （ P 〉 0. 05 ）. Conclusion Photodynamic therapy has an additional benefit to scaling and root planing in treating patients with moderate and severe chronic periodontitis.
