Carisolv处理根管后对冠方微渗漏影响的实验研究

目的:探讨Carisolv应用于根管化学机械预备后对根管冠方微渗漏的影响。方法:将48例符合纳入标准的离体牙随机分为3组,在根管预备过程中分别采用20 g/L氯亚明、Carisolv、EDTA处理根管,并均采用冷牙胶侧方加压技术进行根管充填。扫描电镜观察各组根管充填剂与根管壁之间的黏结效果;染色法检测根管冠方微渗漏的长度。采用SPSS 16.0软件包对结果进行单因素方差分析。结果:扫描电镜观察发现氯亚明和Carisolv组根管充填剂与根管壁间均存在微缝隙,最大宽度分别为64μm和10μm,EDTA处理组充填剂与根管壁贴合紧密。微渗漏测量显示,EDTA组染料渗入长度最低,与其他两组相比差异均有统计学意义(P<0.05);其次为Carisolv组,但与氯亚明组相比无明显差异(P>0.05)。结论:Carisolv作为根管预备化学制剂,对根管冠方微渗漏有一定影响。

The Experimental study of crown microleakage after Carisolv processing of root canals

AIM:To evaluate the effect of Carisolv as root canal preparation agent on crown microleakage.METHODS:Forty-eight extracted teeth which were dyed with methylene blue were randomly divided into 3 groups,and the root canals were prepared with 20g/L chlorine yaming,Carisolv and EDTA respectively.All 48 root canals were filled by cold lateral condensation technique.Root canal crown microleakage was determined by scanning electron microscope.The length of micorleakage was measured by dye penetration test.SPSS 16....
