摘　　要：目的　探讨N 单氯氨基丁酸化学手器去龋材料的去龋作用 ,为临床应用提供理论依据。方法　采用离体龋坏牙实验 ,通过龋齿检知液、光学显微镜、扫描电镜观察 ,比较该去龋材料与常规牙科电动机械去龋效果、玷污层以及对表面牙组织结构的影响。结果　龋齿检知液、光镜和电镜的观察发现 ,N 单氯氨基丁酸去龋材料与牙科电动机械龋齿检知液阳性率均为零 ,无残留龋 ,实验组细菌侵入层 1例 ,统计学 χ2 检验分析两组阳性率差异无显著性 (P >0 0 5 ) ;且均存有玷污层。　结论N 单氯氨基丁酸去龋材料效果基本同于牙科电动机械 。Objective To study the efficiency of chemo hand instrument removal material Methods The effect on caries removal of N monochlorochloraminobutyric acid and the electrical dental instrument was detected by the caries detection , microscope and SEM Results The positive for the caries detection and residual caries were zero in both groups Conclusion The effect on caries removal of N monochlorochloraminobutyric acid is almost the same as the control
