目的:评价电子镇痛仪在超声波龈上洁治术(洁牙)中的镇痛效果。方法:将接受洁牙治疗的病人230例随机分成两组:实验组132例,采用超声波洁牙机联合电子镇痛仪洁牙;对照组98例,单纯用超声波洁牙机洁牙。两组洁牙后即刻问诊了解洁牙过程中的酸痛感,通过统计分析,评价电子镇痛仪的功效。结果:实验组无痛率为77%,对照组为46%(P<0.05);酸软不适程度实验组比对照组亦明显减少。结论:在洁牙治疗过程中联用电子镇痛仪简便、安全、有效,值得在临床中推广应用。
Objective: To evaluate the analgesic effect of electronic analgesia in ultrasonic supragingival scaling (dentifrice). Methods: Two hundred and ten patients were randomly divided into two groups: experimental group (n = 132), ultrasonic scaler combined with electronic analgesia instrument (n = 98) and control group (n = 98). Immediately after the two groups of teeth cleaning ask about the pain during the cleaning process, through statistical analysis, evaluation of the efficacy of electronic analgesic instrument. Results: In the experimental group, the painless rate was 77% in the control group and 46% in the control group (P <0.05). The degree of acidosis was significantly lower in the experimental group than in the control group. Conclusion: The combination of electronic analgesia instrument is simple, safe and effective in the treatment of dentifrice. It is worth to be popularized in clinic.
