【摘要】：目的评价及对比应用劲润牙本质保护膜（Hybrid coat）与Gluma脱敏剂两种药物后，对全冠预备后，活髓牙产生的牙本质敏感症状的治疗效果。方法因牙列缺损而行固定桥修复的50例l10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，A组在牙体预备后表面用劲润牙本质保护膜处理，B组在牙体预备后其牙面用Gluma脱敏剂处理，在备牙后（隔日）和戴牙前（7天后），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。结果两组药物均显示出良好的脱敏效果，但经前后比对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，两者有效率差别在统计学上有意义。结论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。
[Abstract]:Objective to evaluate and compare the therapeutic effect of (Hybrid coat) and Gluma desensitizer on dentine sensitive symptoms of active pulp teeth after full crown preparation. Methods 50 cases of l10 abutment teeth repaired by fixed bridge for dentition defect were randomly divided into two groups. The surface of group A was treated with dentine protective film after tooth preparation. The tooth surface of group B was treated with Gluma desensitizer after tooth preparation. After tooth preparation (alternate day) and before wearing tooth (7 days later), two groups of abutments were treated with air-conditioned stimulation and groping stimulation. The sensitivity of teeth was recorded, and the curative effect was evaluated and compared. Finally, the curative effect before wearing teeth was analyzed statistically. Results both groups showed good desensitization effect, but the hypersensitivity symptom of abutment dentin treated with Gluma desensitizer was better than that before and after treatment. The difference of effective rate between the two groups was statistically significant. Conclusion Jinrun dentin protective film can play a good role in the treatment of dentine hypersensitivity after full crown preparation.
