The purpose of this in vitro study was to analyze the residual dentinal surfaces following caries removal using two chemomechanical methods (Papacarie Duo and Carie Care), by scanning electron microscopy (SEM).
Twenty extracted primary molars with active occlusal carious lesions were randomly assigned two groups depending on the CMCR agent used for the caries excavation - Group 1 - with Papacarie Duo and Group - 2 with Carie Care. After the caries excavation, the specimens were subjected to SEM analysis.
Though both the agents showed the minimal smear layer with the patent dentinal tubules, Carie care showed patent dentinal tubules with a clearly exposed peritubular and intertubular collagen network.
Carie Care treated surface exhibited better surface morphology of residual dentin.
本体外研究的目的是通过扫描电子显微镜(SEM)分析使用两种化学机械方法(Papacarie Duo和Carie Care)去除龋坏组织后的剩余牙本质表面。
20颗有活动性咬合面龋损的拔除乳牙根据用于龋洞预备的化学机械去龋剂随机分为两组——第1组使用Papacarie Duo,第2组使用Carie Care。龋洞预备后,对标本进行SEM分析。
尽管两种试剂均显示有开放牙本质小管的最小玷污层,但Carie Care显示牙本质小管开放,有明显暴露的管周和管间胶原网络。
Carie Care处理的表面显示出更好的剩余牙本质表面形态。
