Vector系统应用于牙周基础治疗的临床研究

目的研究Vector系统进行牙周基础治疗的临床效果。方法采用口内自身对照方法,选择58例慢性牙周炎患者,口内A、D区设为试验组,B、C区设为对照组。所有患者行超声洁治后,试验组应用Vector系统行龈下刮治及根面平整术（scaling and root planning,SRP）,对照组应用Gracey刮治器械行SRP。对2组SRP的治疗时间,SRP前（基线期）及SRP后1、3、6个月的龈沟出血指数、探诊出血、探诊深度及附着水平进行比较,视觉模拟疼痛评级法（visual analogue scale,VAS）评定2组的疼痛程度。结果试验组每区的SRP治疗时间为（25.15±1.35）min,明显短于对照组的（40.11±1.08）min（Z=3.625,P〈0.05）。SRP后各观察时点,2组的各项牙周指数较治疗前均有明显改善（P〈0.05）,但2组间各项牙周指数的差异均无统计学意义（P〉0.05）。试验组SRP结束时（Zc=2.356,P〈0.05）及治疗后1d（Zc=3.138,P〈0.05）的VAS评分明显低于对照组。结论Vector系统能缩短临床操作时间,提高牙周基础治疗舒适度,有效改善慢性牙周炎的临床症状。

Clinical Study of VectorTM System in Periodontal Therapy

Objective To evaluate the clinical effect of VectorTM system in periodontal therapy.Methods In this split mouth self-control design study,58 patients suffering chronic periodontitis were included.After ultrasonic scaling,each patients' teeth in right-side were treated by subgingival scaling and root planning with VectorTM system(test group),another side were performed by Gracey(control group).All clinical parameters including plaque index(PLI),sulcus bleeding index(SBI),bleeding on probing(BOP),probing dept...
