目的：评价 Vector治疗仪用于牙周翻瓣术中的临床疗效。方法选择左右侧需行牙周翻瓣术的37例慢性牙周炎患者，试验组为患者一侧行牙周翻瓣术，Vector治疗仪进行根面平整，对照组为患者另一侧行牙周翻瓣术，Gracey刮治器行根面平整，两组于术前、术后3、6个月分别检测牙周探诊深度（probingdepth，PD）、附着丧失（clinical attachment loss，CAL）、菌斑指数（plaque index，PLI）和龈沟出血指数（sulcus bleeding index，SBI）。结果术后3、6个月两组各项临床指标均较术前明显改善（P ＜0．05），两组组间PD、PLI、SBI值比较差异均无统计学意义（P ＞0．05）；而两组间CAL值比较差异有统计学意义（P ＜0．05）；两组在控制牙槽骨吸收疗效上差异无统计学意义。结论 Vector治疗仪应用于牙周翻瓣术治疗慢性牙周炎的疗效优于单纯翻瓣术。

Objective To evaluate the clinical efficacy of flap surgery with VectorTM-ultrasonic system. Methods Thirty Seven patients with chronic periodontitis were recruited into this study,with a total of 84 teeth in which probing depth of two sites was over 5 mm.The subj ects were randomized into two groups. After scaling and root planning in six weeks,the experimental group received flap surgery with VectorTM-ultrasonic system,while the control group received flap surgery only.For both groups,the following inde-xes were recorded at the time of baseline (before root planning),3 month and 6 months after the treat-ment:probing depth (PD),clinical attachment loss (CAL),plaque index (PLI)and sulcus bleeding index (SBI).Results At the time of 3 and 6 months after the treatment,both groups showed significant im-provement in their examined indexes.The experiment group showed a greater gain in PD and CAL com-pared with the control group at 1 and 3 months,though there were no significantly difference in PD,PLI and SBI between the two groups at the time 3 and 6 months (P>0.05).There was significant difference in CAL between the two groups at the time 3 and 6 months (P <0.05).Conclusion Following both thera-peutic modalities,there were marked clinical improvements for the chronic periodontitis at the time of both 3 and 6 months compared with base line.And flap surgery with VectorTM-ultrasonic system is more effective.
