摘　　要：目的为临床选择牙周基础治疗龈下刮治术的方式提供参考。方法将35例轻中度慢性牙周炎患者随机分为2组,行口腔卫生宣教及全口超声龈上洁治,并填写牙科畏惧量表(dental fear survey,DFS)评估患者畏惧水平。2组患者分别使用Vector治疗仪和P5治疗仪进行龈下刮治术,术后再次填写DFS。治疗前及治疗后1个月监测菌斑指数(plaque index,PLI)、探诊出血(bleeding on probing,BOP)和探诊深度(probing depth,PD)等各项临床指标,监测治疗前后临床指标及患者心理畏惧水平的变化。结果患者使用Vector系统和P5系统进行龈下刮治后各项临床指标均较术前明显改善(P<0.05),2组间BOP和PD变化的差异无统计学意义(P>0.05),PLI的改善Vector组优于P5组(P<0.05)。Vector组治疗后患者DFS得分由51.28±19.61降低为49.16±17.21,差异无统计学意义(P>0.05);P5组治疗后患者DFS得分由49.41±16.14增加至50.82±15.86,差异有统计学意义(P<0.05)。2组DFS得分变化的差异有统计学意义(P<0.05)。结论在轻中度慢性牙周炎龈下刮治术中,Vector系统与P5系统均可获得确切的临床疗效,均不会增加患者在龈下刮治过程中的畏惧水平,而保持患者心理状态的稳定性。Objective To compare the clinical efficacy and the change of fear level during subgingival scaling, using Vector^TM-system or P5 ultrasonic system. Methods Thirty-five patients suffered from mild to moderate periodontitis were randomly divided into two groups. After OHI（ oral hygiene instruction） and supragingival scaling, they were treated by subgingival sealing using Vector^TM-system or P5 system, respectively. DFS was evaluated right after the treatment. PLI （plaque index） and BOP （bleeding on probing） were recorded and PD （probing depth） was measured at haseline, one month after treatment. Results At one month evaluation, both groups showed improvement in clinical parameters. No statistically significant differences in PD and BOP could be observed between patients treated by Veetor^TM-system and P5 system, while PLI had greater improvement in patients treated by Vector^TM-system. In Vector^TM -system group, DFS score decreased from 51.28 ± 19.61 to 49.16 ± 17.21, which was not statistically different （ P 〉 0.05 ）. While in P5 group, the DFS score increased from 49.41 ± 16.14 to 50.82 ± 15.86, which had a statistical difference （ P 〈 0.05 ）. The changes of the two groups in the DFS scores were statistically significant （ P 〈 0.05 ）. Conclusion During initial periodontal treatment for the patients with mild to moderate periodontitis, Vector^TM-system could achieve a comparable clinical efficacy as P5 system and will not strengthen the fear level of the patients during subgingival scaling thus to stabilizing the patients＇ psychological status.
