目的 观察硝酸银和碘伏消毒后牙敏感中龋的临床疗效。方法 选择364颗后牙敏感中龋随机分成 治疗组和对照组各182颗,治疗组窝洞用硝酸银和碘伏消毒,对照组用75％酒精消毒。结果 硝酸银和碘伏消毒 治疗组有效率为99.4％,75％酒精消毒对照组有效率为75.8％。两组比较差异有显著性,P<0.05。结论 硝酸银和 碘伏消毒后牙敏感中龋窝洞疗效明显优于75％酒精消毒,是治疗牙敏感中龋的较理想方法。

Objective To pro into observing the clinical curative effect of sensitive middle dental caries after disinfecting with the silver nitrate and iodoform. Methods 364 dents molares of sensitive middle dental caries were Choosed to divide into at random treat group and contrast group, each was 182 respectively, treat group that the hole of sensitive middle dental caries is disinfect with the silver nitrate and iodoform, and contrast group were disinfect with 75% of the alcohol. Results Treat group efficient by treated with the silver nitrate and iodoform was, contrast group efficient by 75% alcohol disinfected was, there is significance in two groups of comparative differences, P<0.05. Conclusions Curative effect for hole of sensitive middle dental caries with the silver nitrate and iodoform disinfected is obviously superior to 75% of the alcohol disinfected. It was a more ideal method to Treat sensitive middle dental caries.
