牙周超声治疗仪与Gracey刮治器治疗牙周炎疗效的对照研究

Comparative Study of Periodontal Iltrasonic Therapeutic Apparatus and Gracey Scraper in the Treatment of Periodontitis

目的:对比Gracey刮治器与牙周超声治疗仪对牙周炎的临床疗效。方法:80例牙周炎患者按照简单随机分组法随机分为两组,每组40例,对照组行Gracey手工刮治器治疗,观察组行Vector牙周超声治疗仪治疗,比较两组治疗前后菌斑指数(PLI)、牙周袋深度(PD)、临床附着丧失(CAL),牙龈指数(GI)和疼痛评分。结果:治疗1个月后两组菌斑指数(PLI)、探针深度(PD)、牙龈指数(GI)及临床附着丧失(CAL)较治疗前均降低,差异具有统计学意义(P<0.05)。观察组治疗后PLI、GI和PD低于对照组,差异具有统计学意义(P<0.05)。两组治疗后疼痛评分较治疗前均有所下降,观察组治疗后24h内和1个月后疼痛程度评分低于对照组,差异具有统计学意义(P<0.05)。结论:Gracey刮治器与牙周超声治疗仪对牙周炎均有很好疗效,牙周超声治疗仪的疗效更为显著,值得临床推广。

Objective: To compare the effect of Gracey scaler and periodontal ultrasonic therapeutic apparatus in the treatment of periodontitis. Methods: 80 periodontitis patients were randomly divided into a control group and an observation group according to random number table and 40 cases in each group. Gracey traditional manual scaler was used in the control group and Vector periodontal ultrasonic therapeutic apparatus were used in the observation group. The dental plaque index( PLI),probe depth( PD),gingival index( GI) and clinical attachment loss( CAL) and VAS were compared. Results: One month after the treatment,dental plaque index( PLI),probe depth( PD) and clinical attachment loss( CAL),gingival index( GI) were both improved and the difference was statistically significant( P < 0. 05),the PLI,GI and PD in the observation group were better than that in the control group( P < 0. 05). The VAS were both reduced in two groups and the difference was statistically significant( P < 0. 05),and the VAS in the observation group reduced more than that in the control group( P < 0. 05). Conclusion: Both of Gracey scaler and periodontal ultrasonic therapeutic apparatus has sound effect for periodontitis,periodontal ultrasonic therapeutic apparatus has better effect and it is of high clinical application value.
