摘要
目的:探究Nd:YAG激光联合Er:YAG激光辅助治疗广泛型侵袭性牙周炎(generalized aggressive periodontitis,GAgP)的临床疗效。方法:选取12例广泛型侵袭性牙周炎患者,将同颌对称同名牙随机分配为对照组(超声龈下刮治+根面平整术)和实验组(超声龈下刮治+根面平整术+激光治疗),临床检查患者治疗前、治疗后1、3个月探诊深度(probing depths,PD)、出血指数(bleeding index,BI)的改变。结果:术后1个月及3个月,实验组PD、BI均低于对照组(P<0.05)。结论:Nd:YAG激光联合Er:YAG激光辅助龈下刮治根面平整术治疗广泛型侵袭性牙周炎,可取得较好疗效,优于单纯使用龈下刮治根面平整术。
Objective: To investigate the clinical efficacy of Nd:YAG laser combined with Er:YAG laser as an adjunctive therapy on generalized aggressive periodontitis(GAgP). Methods: Twelve patients with generalized aggressive periodontitis were randomly assigned into 2 groups, the control group(subgingival scalling+ SRP) and the experimental group(subgingival scalling+ SRP+ laser). Clinical examination of patients with pre-treatment, 1 month, 3 months after treatment, the clinical parameters including probing depth(PD) and bleeding index(BI) were measured.Results: PD and BI in the experimental group were lower than those in the control group at 1 month and 3 months after treatment(P<0.05).Conclusion: Nd:YAG laser combined with Er:YAG laser as an adjunctive therapy on subgingival scalling + SRP for the treatment of generalized aggressive periodontitis can achieve better curative effect than the simple subgingival scalling+ SRP.
