摘　　要：目的比较两种超声龈下刮治联合手工根面平整术治疗慢性牙周炎的临床疗效并评价疼痛程度。方法 16例慢性牙周炎患者共有205颗患牙纳入临床观察,以超声洁治后1周作为基线,采用分口设计方案,实验组应用磁致伸缩牙科综合治疗仪(PR-ZH1)超声龈下刮治和手工根面平整术,对照组为压电陶瓷式超声龈下刮治和手工根面平整术。治疗完成后即刻使用视觉模拟评分法(visual analogue scale,VAS)进行疼痛度评价。基线和基础治疗后3个月、6个月测量菌斑指数、牙龈出血指数、探诊深度和附着丧失。结果实验组产生的疼痛度(3.5±2.6)显著低于对照组(5.0±2.11),实验组和对照组在治疗后3个月和6个月牙周指数与基线比较均有显著下降,差异有统计学意义(均P<0.05)。两组治疗后牙周指标比较无统计学差异。结论磁致伸缩超声龈下刮治(PR-ZH1)联合手工根面平整术和压电陶瓷式超声龈下刮治联合手工根面平整术均可以有效改善临床牙周指标,磁致伸缩超声龈下刮治联合手工根面平整术可能会增加患者治疗的舒适度,增加患者的依从性。Objective To compare the clinical effects following non-surgical periodontal treatment with magnetostrictive dental unit PR-ZH1 or with combination of piezoelectric ultrasonic subgingival scaling and root planing with hand instrument（SRP） for patients with chronic periodontitis.Methods 16 patients with chronic periodontitis were randomly treated in a split-mouth design with magnetostrictive dental unit PR-ZH1 and root planning with hand instrument（test group） or a combination of piezoelectric ultrasonic subgingival scaling and root planing with hand instrument（control group）.The degree of discomfort experienced during the treatment was graded by the patient using visual analogue scale（VAS） immediately after the completion of test and control treatment procedures.The following clinical parameters were recorded by a calibrated and blinded examiner in baseline,3 months,6 months respectively： plaque index（PLI）,bleeding index（BI）,probing depth（PD） and attachment loss（AL）.Results Probing pocket depth,clinical attachment level and bleeding index improved in 2 groups from baseline to the end of 3 months and 6 months;however,there was no difference between the 2 instrumentation modalities.The patients perceived less pain with magnetostrictive dental unit PR-ZH1 during therapy.Conclusion Both of magnetostrictive dental unit PR-ZH1 ultrasonic subgingival scaling with manual instrument and piezoelectric ultrasonic subgingival scaling and root planing with hand instrument can effectively improve the clinical periodontal index.The treatment is effective,but magnetostrictive dental unit PR-ZH1 increases patients comfort and relieves the pain.
