摘要
目的评价电子镇痛仪在超声洁治术中的镇痛作用。方法将81例(包括慢性牙周炎患者49例,龈炎患者32例)需要进行超声洁治的牙周病患者,按随机原则在其上、下颌各选一侧使用电子镇痛仪,另一侧作为自身对照。患者和治疗医师均双盲。采用视觉模拟量表,请患者为4个象限的治疗感受打分,同时做问卷调查评价其主观疗效。结果问卷调查中,79·0%的受试者认为电子镇痛仪有减轻疼痛的作用,而双盲实际检测的有效率为46·9%。将所有患者根据有无附着丧失分组,慢性牙周炎组又按性别、年龄和部位分组,组间的有效率差异均无统计学意义。结论电子镇痛仪能有效减轻部分患者超声洁治术中的牙齿酸痛、不适,主观感觉疼痛减轻的患者数远多于双盲实际检测出的有效人数,说明电子镇痛仪的镇痛效果具有一定的安慰剂效应。
Objective To evaluate the effect of electronic dental analgesia （EDA） device -- Team Up Duo during ultrasonic scaling. Methods The clinical trial was conducted as a randomized double-blind split-mouth design. Eighty-one patients requiring ultrasonic scaling were selected as subjects. Patients received treatment using the EDA device either in an active or an inactive state in paired quadrants. The patients scored their pain/discomfort levels with visual analog scale （VAS） after each procedure and filled a questionnaire. Results In questionnaire, 79. 0% patients felt EDA could relieve pain/discomfort during ultrasonic scaling. But the double-blind test showed that Team Up Duo was effective in 46. 9% patients overall. The effective rate was 55.1% and 34. 4% in groups with or without attachment loss, respectively. In CP group, the success rate of EDA was not statistically significantly different between the groups according to sex, age or site. Conclusions When using Team Up Duo during ultrasonic scaling, most patients subjectively believed that it was effective for controlling pain. In fact, this EDA device was effective in partial patients.
