摘　　要：目的:评价3种脱敏剂对冠桥活髓基牙预备后牙本质敏感的疗效。方法:局麻下,按照修复体的常规要求行活髓牙的牙体制备。将68例(共153颗)患者随机分为四组:Gluma脱敏剂组,极固宁脱敏剂组,"劲润"牙本质保护膜组,对照组。所有预备后的基牙均佩戴暂时冠,使用RelyX TempNE临时粘固。采用可视分级评价法(VAS)记分评价探针刺激以及空气刺激预备牙的敏感程度。结果:Gluma脱敏剂组:治疗后的触觉敏感性VAS值(2.51±1.13)和空气敏感性VAS值(3.09±0.98)与治疗前触觉敏感性VAS值(4.92±1.35)和空气敏感性VAS值(5.88±1.21)比较差异有统计学意义(P<0.05)。极固宁脱敏剂组:治疗后的触觉敏感性VAS值(3.03±1.58)和空气敏感性VAS值(3.17±1.63)与治疗前触觉敏感性VAS值(4.67±2.36)和空气敏感性VAS值(6.01±1.17)比较差异有统计学意义(P<0.05)。"劲润"脱敏剂组:治疗后的触觉敏感性VAS值(2.56±1.84)和空气敏感性VAS值(2.86±1.19)与治疗前触觉敏感性VAS值(5.21±1.84)和空气敏感性VAS值(5.91±0.95)比较差异有统计学意义(P<0.05)。对照组,VAS记分试验前后差异无显著性(P>0.05)。结论:使用3种脱敏剂可有效缓解备牙后的牙本质敏感症状。Objective： To evaluate the effect in preventing dentine hypersensitivity by using three desensitizers on the prepared vital pulp abutment teeth of the crown and bridge.Methods： Vital teeth that required restorations were prepared according to the standard procedure.68cases,153 prepared vital pulp abutment teeth were randomly divided into four groups： One group were treated with Gluma desensitizer,and the other group were treated with Green Or desensitizer,and next were treated with Hybrid Coat,the finally group was chosen as the control group.All prepared teeth were protected with temporary restorations,which were cemented with RelyX TempNE.Visual analog scale（VAS） was used to evaluate the scores of tactile test and air blast test.Then the results were analyzed using statistics software.Results： For desensitizer groups： significant differences were found between scores of tactile test and air blast test（pre-treatment） and scores of tactile test and air blast test（post-treatment）（P 0.05）.No significant difference was found within experimental groups.Conclusions： Dentine hypersensitivity can be effectively released by three desensitizers after teeth preparation.
