摘　　要：因牙列缺损而行固定桥修复的50例110颗基牙进行牙体预备,随机地将缺失区两侧预备后的基牙分为两组:劲润牙本质保护膜组和Gluma脱敏剂组,在备牙后(隔日)和戴牙前(7 d后),对两组基牙试验区行冷气刺激和探划刺激,记录牙齿敏感程度,并评定对比其疗效,最后统计学分析戴牙前评定的疗效。两组药物均显示出良好的脱敏效果,但经前后对比劲润牙本质保护膜较Gluma脱敏剂处理过的基牙牙本质敏感症状改善明显,两者有效率比较差异有统计学意义(P<0.05)。劲润牙本质保护膜对全冠预备后的活髓牙牙本质敏感症状能发挥良好的治疗作用。110 prepared vital pulp abutment teeth of 50 cases were randomly assigned to two groups after fixed bridge prosthesis：a group was treated with Hybrid coat dental adhesive resin cement, and the other was treated with Gluma desensitize. Using stimulation probing method and air conditioning stimulation experiments to evaluate the degree of dentine hypersensitivity after the tooth preparation on alternate days and 7 days later, and compared and recorded the effect of hypersensitivity. Finally the results were analyzed using statistics software. After 7 days, both drugs showed good effect of desensitization , but the symptom of dentin hypersensitivity by using Hybrid coat dental adhesive in experiment group was obviously relieved. Hybird coat has good therapeutic effects on the dentin hyper- sensitivity of the teeth prepared for crowns.
