Carisolv化学机械法在乳牙龋去腐的临床应用

Caries Removal of Deciduous Teeth with Carisolv Chemomechanical Method

目的:比较使用C ariso lv化学机械法和传统机械法在乳牙龋去腐时的工作时间、对局麻的需求。方法:所有样本由患有牙合面龋的儿童乳牙组成,龋损达到牙本质。根据临床标准判断去腐效果,在两种方法中均记录工作时间的长短,是否采用局麻。采用t检验和χ2检验进行统计学分析。结果:采用C ariso lv法的工作时间[(8.4±3.1)m in]长于传统机械法[(2.8±2.3)m in](P<0.001),C ariso lv法减少局麻的使用(P<0.05)。结论:在乳牙去腐时,虽然C ariso lv法工作时间长,但是可以减少局麻的使用。

Objective ：To compare the working time and the need for local anesthesia for caries removal in deciduous teeth between the chemomechanical Carisolv and the conventional mechanical method.Method：All deciduous teeth were collected fromchildren who had occlusal carious lesions into dentin. The efficiency in caries removal was judged on the basis of clinical criteria. Working time and need for local anesthesia were recorded for both methods. Statistical analysis was performed using the student＇s t test and chi-square test. Results;Working time with the Carisolv method [-（8.4 ±3. 1） min]was much more prolonged than that with the conventional mechanical method [（2. 8±2. 3） mini （P〈0. 001）,but it reduced the need for administration of local anesthesia（P Carisolv, although working time was more prolonged, may reduce the need for local anesthesia.
