目的观察烤瓷基牙预备后涂抹黏结剂基牙敏感症状的改善情况。方法选择拟进行烤瓷修复的患者87例(患牙224颗),根据随机数字表将患牙随机分为试验组(112颗)和对照组(112颗)。牙体预备后,试验组涂布黏结剂,对照组不做任何处置。临时冠摘除后进行相关指标检测,比较观察试验组和对照组的临床疗效。结果在探诊、冷风刺激和冷水冷诊的检测中,试验组的疼痛与对照组比较,差异明显。结论应用黏结剂能有效改善牙体预备后牙本质敏感症状。
Objective To observe the improvement of adhesive sensitivity of abutments after preparation of porcelain abutments. Methods Totally 87 patients (224 teeth) were enrolled in this study. The teeth were randomly divided into experimental group (112) and control group (112) according to random number table. Tooth preparation, the test group coated adhesive, the control group without any treatment. After the removal of the temporary crown related indicators detection, comparative observation of the clinical efficacy of the experimental group and the control group. Results In the exploration, cold stimulation and cold water cold test in the test group of pain compared with the control group, the difference was significant. Conclusion The application of adhesive can effectively improve dentine hypersensitivity after tooth preparation.
