[摘要]目的：观察Super-Bond C&B 在口腔临床治疗磨牙合面重度磨耗致牙本质敏感的作用。方法：收集磨牙咬合面因重度磨耗所致牙本质敏感症的62例患者（共128颗患牙）进行研究，采用自身对照方法，在同一标准下进行即刻和6个月后疗效比较和6个月后充填物的脱落情况分析。结果：即刻治疗有效率为97.66%，6个月后治疗有效率为89.84%，6个月后10颗患牙的充填物脱落，脱落率为7.81%。结论：Super-Bond C&B对磨牙重度磨耗致牙本质敏感具有较好的治疗效果，可以推广应用，但该种材料仍存在一定的脱落情况。

Abstract：Objective  Observation of Super-Bond C&B is used to improve effects of occlusal advanced wear and dentine hypersensitivity. Methods 62 patients with occlusal advanced wear and dentine hypersensitivity （62 patients，128 teeth） were selected and then treated by Super-Bond C&B. To compare instant effectiveness and that of 6 months after treatment with the unified standard by self control and observe the falling off of fillings 6 months later after treatment. Results  The instant effective rate is 97.66% and that 6 months later is 89.84% with ten fillings falling off. The falling rate is 7.81%. Conclusion  Super-Bond C&B is an effective desensitizer for occlusal advanced wear and dentine hypersensitivity. However， there is still some shedding of this material， that Patients should be reviewed regularly.

牙本质敏感症是口腔临床中常见的疾病之一，是牙遇到外界刺激如冷、热、酸、甜以及咀嚼硬物、刷牙時所产生的酸痛症状[1]。在口腔临床修复工作中， 常遇到牙齿重度磨耗的患者，此时牙齿表面釉质完全磨损，牙本质暴露、出现凹坑状光滑缺损。如用冷刺激或者探针轻划牙合面缺损处，患者出现明显的刺激痛，发作迅速、疼痛尖锐、时间短暂，如若长期不治疗甚至会发展为牙髓炎等疾病。这类患者多见于夜磨牙症、咬合紊乱或经常咀嚼硬物、不恰当的刷牙方式等。目前，治疗方法很多，主要分为药物脱敏、激光脱敏以及物理治疗三类。简单的有氟化物、硝酸银脱敏，也可使用蛋白螯合剂、树脂类脱敏剂以及激光照射发热封闭脱敏等[2-7]。这些药物和激光脱敏疗法虽然具有一定的效果，但是远期依然效果不佳，况且本症存在着自发性的脱敏过程，所以任何药物疗效的评价都是极其困难的。……
