摘　　要：目的评价在全瓷固定桥修复治疗中牙本质保护膜防治活髓基牙牙本质过敏的效果。方法选择118例患者,236颗进行全瓷固定桥修复治疗的活髓基牙,平均分为2组,试验组基牙采用牙本质保护膜处理,对照组基牙采用质量分数75%氟化钠甘油处理,暂时冠桥修复,7 d后观察应用效果。结果牙本质保护膜的有效率为96.61%,75%氟化钠甘油的有效率为66.10%,2组有效率差异具有统计学意义(χ2=18.10,P<0.05)。结论在全瓷固定桥修复中,牙本质保护膜对防治活髓基牙牙本质过敏有较好的临床效果。Objective To evaluate the effects of protective coat for dentin in vital pulp abutment teeth for all ceramic fixed bridge restorations. Methods One hundred and eighteen cases, two hundred and thirty-six prepared vital pulp a- butment teeth for all ceramic fixed bridge restorations, were randomly divided into two groups. Protective coat for dentin was used in the experimental group after tooth preparation, and 75% sodium fluoride glycerol was used in the control group after tooth preparation. The effect was contrasted after 7 days, then the results were analyzed using statistics soft- ware. Results After 7 days, protective coat for dentin group had significant desensitization compared with control group （ P 〈 0.05 ）. Conclusion Protective coat for dentin can effectively prevent dentine hypersensitivity after tooth preparation in fixed bridged restoration.
