摘要
目的:用扫描电镜技术对化学机械去龋法和传统去龋法去除乳牙龋损牙本质后的微观形态进行比较。方法:选取12个深龋的离体乳磨牙,随机分为对照组、机械法去龋组、Carisolv去龋组,去龋后用扫描电子显微镜分别观察3组乳磨牙窝洞底部形态。结果:对照组牙本质崩解破坏,可见碎屑和残渣,牙本质小管形态不完整;机械法去龋组牙本质表面有不规则的颗粒和碎片,有玷污层形成,牙本质小管口堵塞;Carisolv去龋组未见碎屑和残渣以及玷污层,牙本质小管清楚可见。结论:Carisolv去龋法对乳牙的牙本质龋效果优于机械法去龋组。
AIM： To compare the different dentine surface characteristics of the primary teeth caries prepared with Carisolv and conventional drilling. METHODS： Twelve carious primary molars were randomly divided into three groups： contrast group, conventional drilling group and Carisolv group, four teeth in each group. All teeth were observed by scanning electron microscope （SEM）. RESULTS： The dentine surface characteristics in the contrast group showed anomaly dentine structure with some detritus and residum. The dentinal tubules were not completely exposed. The characteristics of the drilling group appeared rougher with irregular particles scattered throughout the surface. The well - defined smear layer was detected. The dentine tubule orifices were plugged. The cavity surface of the Carisolv group showed that the smear layer was consistently removed and the dentinal tubules of carious area were sufficient exposed. CONCLUSION： The caries removal effect of Carisolv group was more excellent than that of the conventional drilling group.
