【摘要】 目的：本临床研究的目的是为了比较Vector治疗仪与普通手工器械在慢性牙周炎基础治疗中的临床疗效以及评估两组患者的主观疼痛度。方法：临床选择慢性牙周炎患者30例作为研究对象。采用自身对照,将其随机分成2组：1、4象限区为Vector组,2、3象限区为手工组。所有患者行龈上洁治一周后,手工组用Gracey刮治器行刮治及根面平整术,Vector组用新型超声装置Vector系统行龈下刮治及根面平整术。在龈下刮治及根面平整术治疗前(基点)和治疗3个月后,分别记录并比较两组的菌斑指数(plaque index, PLI)、龈沟出血指数(sulcus bleeding index, SBI)、探诊深度(Probing depth, PD)等临床指标。Vector组和手工组的所有患牙行刮治治疗后用视觉模拟疼痛评级法(visual analogue scale, VAS)记录得分并比较两组患者治疗过程中的主观疼痛度。结果：(1) Vector组和手工组患者行龈下刮治和根面平整术后3个月各组的PLI、SBI、PD较治疗前均有明显降低(P<0.05)。两组间临床指标进行比较SBI、PD变化无明显差异(P>0.05),而在PLI减少方面,Vector组优于手工组(P<0.05)。(2) Vector组治疗时和治疗后的疼痛评分低于手工组,即在使用Vector系统治疗时患者的疼痛不适感比使用手工Gracey器械轻(P<0.05)。结论：Vector牙周系统在慢性牙周炎基础治疗中可获得良好的临床效果并能减轻患者治疗时的主观疼痛度,患者易于接受,为临床提供了帮助。更多还原

【Abstract】 Objective:The purpose of this clinical study was to evaluate the difference of the curative effect on the periodontal disease and the pain degree of patients between the root planning with conventional hand instruments and Vector ultrasonic system. Methods: Thirty patients with chronic periodontitis were involved in this study which was used self-control design. All the subjects were randomly divided into two groups and had received the subgingival scaling. The teeth in quadrant 1 andⅣwere included in Vector group which were scaled with Vector system. Those in quadrantⅡandⅢwere included in hand group which were scaled with Gracey sealers. Scaling and root planning for the Vector group was performed by using the Vector system. All clinical index including PLI(plaque index), SBI(sulcus bleeding index)and PD (Probing depth) were recorded at baseline and 3 months after the treatment. A visual analogue scale(VAS) was used to evaluate the subjective pain degree. Results:PLI, SBI and PD values were significantly decreased after treatment in the two groups (P<0.05). No statistically significant differences in SBI and PD could be observed between patients treated by Vector system and Gracey scalers(P>0.05), while PLI had greater improvement in patients treated by Vector system(P<0.05). The pain value in Vector group was significantly lower than hand group (P<0.05). Conclusion:Vector ultrasonic system relieved discomfortable sensations compared with traditional hand curettes. The Vector ultrasonic system may have an good clinical effect by relieving the discomfort during the therapy.更多还原
