摘　　要：目的比较牙周炎患者对两种超声治疗仪在牙周基础治疗中的临床疗效及患者疼痛感受的差异，以期为临床提供参与。方法选择38例轻、中度牙周炎患者，对患者口内一、四象限用奇数、偶数随机法选择A（Vector治疗仪，德国DURR齿科公司）或B（Suprasson P5 Newtron超声多功能牙科治疗仪，法国赛特力公司）超声治疗仪进行治疗，第2天对二、三象限使用另一系统进行治疗。治疗结束后即刻用视觉模拟评分法（visualanaloguescale，VAS）对患者行疼痛评估。治疗前及治疗后1个月检测菌斑指数（plaqueindex，PLI）、探诊出血（bleedingonprobing，BOP）和探诊深度（probingdepth，PD）等各项临床指标。结果用两种超声系统行牙周基础治疗后，患者PLI、BOP和PD均较术前明显改善（P〈0．01）；两者BOP和PD的改变差异无统计学意义（P〉0．05），与B治疗仪相比，A治疗仪治疗区域的PLI明显改善（P〈0．05）。A、B治疗仪在牙周基础治疗中患者主观感受疼痛VAS值分别为（22．5±7．5）mm和（37．2±11．3）mm，前者约为后者疼痛值的60％，两者差异有统计学意义（P〈0．01）。结论在轻、中度牙周炎牙周基础治疗过程中，A、B两种超声治疗仪均疗效确切，A治疗仪能明显减轻患者在牙周治疗过程中的疼痛感。Objective To compare the clinical efficacy and perception of pain during initial periodontal treatment using VectorTM-system and a conventional ultrasonic system. Methods Thirty-eight patients with mild to moderate periodontitis were debrided using both A-system （VeetorTM-system） and B-system （Suprasson P5 Newtron） in a split mouth design. At baseline, one month after treatment, plaque index（PLI） and bleeding on probing（BOP） were recorded and probing depth（PD） was measured. A verbal analogue scale （VAS） was used to evaluate the perceived pain right after the treatment. Results At one month evaluation, all areas showed an improvement in clinical parameters. No statistically significant differences in PD and BOP could be observed between areas treated by two different systems, while A-system contributed to greater improvement in PLI than B-system. Patients treated with A-system [ （22. 5 ± 7.5）mm] experienced about 60% the amount of pain compared with the conventional ultrasonic device [ （37.2 ±11.3 ） mm ]. Conclusions During initial periodontal treatment for the patients with mild to moderate periodontitis, A-system could achieve a comparable clinical efficacy and reduced pain sensations to conventional ultrasonic device.
