劲润牙本质保护膜防治牙体预备后牙本质敏感的近期疗效观察

目的评价劲润牙本质保护膜(Hybrid coat)对活髓基牙预备后牙本质敏感的防治效果。方法将54例(共115颗)进行固定桥修复行牙体预备的基牙,对缺牙区两侧基牙随机分组,试验组在牙体预备后表面用劲润牙本质保护膜处理,对照组牙体预备后不做任何处理,所有基牙均采用暂时冠修复,备牙后和10天试戴修复体时观察治疗效果,评定疗效,并对戴牙前评定的疗效进行统计学分析。结果经劲润牙本质保护膜处理过的基牙牙本质敏感症状明显改善,两次疗效比价,有效率差别有统计学意义(P<0.05)。结论劲润牙本质保护膜可以有效防治活髓基牙预备后的牙本质敏感症状,值得在临床上推广应用。

Clinical observation of Hybrid Coat dental adhesive resin cement on postoperative hypersensitivity in vital teeth preparation for crown restoration

Objective To evaluate the effect in preventing dentin hypersentivity by using Hybrid coat dental adhesive resin c enaent on prepared vital pulp abutment teeth. Methods 115 prepared vital pulp abutment teeth of 54 cases were randomly divided into experiment group and control group： One was treated with Hybrid coat dental adhesive resin cement, and the other was without any treatment as control. All of the prepared abutment teeth were protected by temporary crowri or bridge. To evaluate the effect of hypersensitivity wheri try in the terminal restorations 10 days later. Then the results were analyzed using statistics software. Results After 10 days, the symptom of dentin hypersentivity by using Hybrid coat dental adhesive resin cement in experiment group was obviously alleviated. Conclusion Conclusion： Dentin hypersentivity can be effectively released by using Hybrid coat dental adhesive resin cement after tooth prepartion.
