摘　　要：目的:探讨Gluma脱敏剂治疗金属烤瓷全冠牙体预备后敏感症的疗效及作用机理。方法:自身配对设计将15例62颗患牙随机分为Gluma治疗组和空白对照组,可视分级评价法(visualanalogscale,VAS)评价其临床疗效;制作离体牙标本,扫描电镜观察Gluma脱敏剂对牙本质小管的封闭作用。结果:Gluma脱敏剂治疗后VAS值(3.43±1.49)与治疗前(6.20±1.20)、对照组治疗后(5.87±1.47)均有显著差异(P<0.05),有效率83.87%;牙本质小管被封闭,表面均匀平整。结论:Gluma脱敏剂能缓解活髓牙全冠备牙后的敏感症状。Objective： To evaluate the effect of Gluma desensitizer on vital teeth postoperative hypersensitivity in crown restoration by both clinical application and SEM study. Methods： 62 teeth （on symmetric position） from 15 patients were divided into two groups randomly by self-paired design. One was treated with Gluma desensitizer and the other with warm sterile water as control. Visual analog scale （VAS） was used obtained by cutting vital human molars occlusally immediately to evaluate the clinical effects. Flat dentin surfaces were after their extraction.After treated with Gluma desensitizer, they were prepared and observed under SEM. Results： VAS value of the study group（3.43±1.49） was significantly different from that of the contral group （5.87±1.74）and that before treatment （6.20±1.20）. The effective rate was 83.87%. Conclusion： Dentin hypersensitivity can be effectively released by Gluma desensitizer after crown preparation.
