不同根管湿润度条件下糊剂充填后根尖封闭性能的体外研究
In vitro study of the apical sealing ability of root canal sealing paste in different wettability
摘要
Abstract
Objective To compare the apical sealing ability of iRoot SP root canal sealing paste in different root canal wettabili-ty .Methods A total of 30 single root canal teeth were divided into three experimental groups randomly(10 teeth in each) ,including dry ,normal and moist conditions ,and filled iRoot SP paste into the root canal wall respectively .After X slice was examined to testi-fy the root canal filling status ,the root canal was filled with continuous and dense root canal .Eight teeth were selected from each group to be dyed by methylene blue .Then a longitudinal section of tooth structure was conducted ,and apical micro leakage level of different sets were measured and compared .The rest samples of each group were observed by scanning electron microscopy after cross cutting .Results The length of apical micro leakage of normal and moist group were less than dry group(P< 0 .05) ,and that of moist group was less than normal group(P< 0 .05) .There were cracks between root canal sealers and root canal dentin walls of each group ,observed by scanning electron microscope .Gaps in the moist group was the smallest ,and those in dry group was the lar-gest .Conclusion The root canal sealing paste could filled root canal closely under moist condition .关键词
