摘　　要：目的评价、对比劲润牙本质保护膜与多乐氟对冠桥活髓基牙预备后牙本质敏感的脱敏效果。方法将60例患者(共137颗活髓牙)随机分为3组:劲润组、多乐氟组、对照组,局麻下活髓基牙行牙体预备后临时冠修复。7 d后去除临时冠,采用可视分级评价法(VAS),观察在活髓基牙表面分别涂抹劲润、多乐氟及蒸馏水前后,机械刺激和温度刺激活髓基牙的敏感程度。结果劲润组和多乐氟组脱敏治疗后VAS值均低于治疗前,并显著低于对照组(P<0.05),而两组间VAS值无统计学差异(P>0.05),对照组脱敏前后VAS值无统计学差异(P>0.05)。结论劲润牙本质保护膜及多乐氟均可有效缓解行全冠预备后的活髓基牙出现的牙本质敏感症状,二者间作用效果差异无统计学意义。Objective To evaluate and compare the desensitization effects of hybrid coat dentin protection film and toro fluorine on crown-bridge preparation of tooth dentin of vital pulp abutment tooth. Methods 60 patients（ total 137 vital pulp teeth）were selected and divided randomly into three groups：hybrid coat group,toro fluorine group and control group. The patientsˊcrowns were temporarily repaired after preparation of teeth dentin for the vital pulp abutment teeth under local anesthesia. Seven days later,the temporary crown was removed;and hybrid coat and toro fluorine,and distilled water were applied on the surface of vital pulp abutment teeth,respectively,and the sensitivity of the vital pulp teeth to mechanical and temperature stimulations was evaluated based on visible analogue scale/score（ VAS ）. Results The VAS values of the hybrid coat group and toro fluorine group after the desensitization treatment were lower than those before the treatment,and were significantly lower than that of the control group（〈0. 05）,while these two groups had no significant difference in VAS value（P〈0. 05）and the control group itself had no statistical difference in VAS value before and after desensitization（P〈0. 05）. Conclusion Both hybrid coat dentin protection film and toro fluorine on crown-bridge prepared tooth dentin of vital pulp abutment tooth can relieve the dentin sensitivity symptoms of vital pulp abutment tooth after full-crown preparation,and they have not statistical difference in efficiency.
