The efficacy of cervitec in the treatment of the tooth hypersensitivity caused by tooth abrasion of the elderly

目的:评价cervitec治疗老年人因牙齿磨损引发的牙本质敏感症的临床疗效。方法:对老年人敏感牙齿分别用cervitec(实验组66颗)和75%氟化钠甘油糊剂(对照组62颗)进行脱敏,4次为一个疗程,观察其即刻、1个月、3个月的疗效。结果:实验组与对照组在即刻疗效上的差异无统计学意义,在1个月、3个月的疗效,两者间差异具有统计学意义。结论:cervitec在治疗老年人因牙齿磨损引发的牙本质过敏症中短期疗效显著。

Objective： To evaluate the efficacy of cervitec in the treatment of tooth hypersensitivity caused by tooth abrasion in elderly patients. Methods： A total of 66 teeth with dentine hypersensitivity in occlusal surface （experimental group） were treated with cervitec and the other total of 62 teeth （control group） was treated with 75% sodium fluoride glycerin paste. 4 times was a course. Then their efficacies at immediately after treatment, one month and three months after treatments were observed. Results： There were significant differences at one month and three months after treatment between two groups, but no significant difference was found at immediately after treatment between two groups （P〈0.01）. Conclusion： Cervitec was proved to be effective in the treatment of elderly patients with dentine hypersensitivity caused by tooth abrasion in a short term.
