  三种脱敏剂预防超声波洁治后牙本质敏感 的疗效比较# 张奇峰* 5 10 15 20 25 30 35 （浙江大学医学院附属第一医院口腔科，杭州，邮编 310003） 摘要：目的：比较三种脱敏剂用于预防超声波洁治后牙本质敏感的疗效。方法：将行超声波 龈上洁治术的患者 180 人随机分为 4 组，A（75% 氟化钠甘油）、B（Gluma 脱敏剂）、C（极 固宁脱敏剂）、D（对照组，生理盐水），分别于洁治前、脱敏治疗 15min、3 个月、6 个月 后用(visual analogue scales，VAS)法对患牙敏感程度进行测试并记录。计算不同时点的 疼痛改善值，并进行统计分析。结果：A、B、C 组疗效均明显优于 D 组；其中 B、C 组较 A 组疗效更加明显；而 B、C 组间疗效差异无统计学意义。讨论：在超声波洁治术后预防性采 取抗敏感处理有助于减少牙本质敏感引起的不适；Gluma 和极固宁脱敏剂用于预防洁治后牙 敏感的效果优于氟化钠。 关键词：口腔内科；超声洁治；牙过敏症； 中图分类号：R781.05 Comparison of three desensitizers in treatment of hypersensitivity after ultrasonic scaling Zhang Qifeng (The First Affiliated Hospital of Medical College, Zhejiang University, Hangzhou, Post Code 310003) Abstract: Objective To observe and compare the therapeutic effects of three desensitizers in treatment of dentine hypersensitivity after ultrasonic scaling． Methods 180 patients having ultrasonic scaling treatment were randomly divided into 4 groups: A (75% sodium fluorode), B(Gluma desensitizer), C(GreenOrTM), D(Control group, sodium). VAS method was used to evaluate the dentine hypersensitivity extent before ultrasonic scaling, 15 minutes after desensitization, 3 months and 6 months later. The improvement among different time points was compared. Results The desensitization valid rates of Group A, B and C was higher than Group D obviously (P＜0．05). It was even higher in Group B and C than Group A. But no difference was found between Group B and C． Conclusion It may be effective to use desensitizers to prevent dentine hypersensitivity after ultrasonic scaling．The therapeutic effect of Gluma desensitizer and GreenOrTM is better than that of 75% sodium fluorode， while the long-term effect leaves room for further investigations． Key words: Endodontology; Ultrasonic scaling; Dentin hypersensitivity 0 引言 在口腔临床中，龈上洁治术多采用超声波洁牙装置。但该治疗后，约 40%±患者会出 ［1］ 。笔者研究了临床常用的三种不同脱敏剂： 75%氟化钠、Gluma、极固宁等用于预防超声洁治后牙本质敏感的治疗效果，现总结如下。 1 材料与方法  40 研究对象 2010 年 10 月至 2012 年 10 月在我院行超声波龈上洁治术的患者 180 人，其  基金项目：教育部高等学校博士学科点专项科研基金资助（
