CarisolvIII凝胶联合低浓度次氯酸钠去除根管壁玷污层效能的体外实验研究

Ability of CarrisolvIII Combined with Low Concentration NaClO to Clean the Smear Layer of Root Canal

目的:探究CarisolvIII凝胶与0.50%NaClO溶液联合使用时,对根管预备过程中产生的玷污层的作用效果。方法:将50颗离体的上颌中切牙随机分为5组,进行根管预备,在预备过程中分别采用5组不同根管冲洗液进行冲洗。电镜扫描观察并比较5组样本根管壁的清洁度、牙本质小管的开放程度和腐蚀程度。结果:实验组中的CarisolvIII凝胶与0.50%NaClO溶液组根管壁的清洁度优于单纯的CarisolvIII凝胶组和0.50%NaClO溶液组。结论:CarisolvIII凝胶与0.50%NaClO溶液联合使用去除玷污层时具有协同作用。

Objective：To investigate the effect of CarrisolvIII combined with 0.5%NaClO on removing the smear layer.Methods：Fifty maxillary incisors were randomly divided into 5groups.During the process of preparation,five different fluids were used to irrigate the root canal.The amount of smear layer and erosion on the surface of the root canal walls were examined with the scanning election microscope.Results：The cleaning of root canal walls using CarrisolvIII combined with 0.5%NaClO was better than the CarrisolvIII or 0.5%NaClO alone,respectively.Conclusion：CarrisolvIII combined with 0.50%NaClO has a synergistic effect on the removal of the smear layer.
