Comparison of apical sealing ability of three bioceramic root canal sealers in vitro
摘要
Abstract
Objective We aimed to compare the apical sealing properties of three endodontic sealers,namely,C-Root SP(C-R),iRoot SP,and GuttaFlow Bioseal(GFB)in vitro.Methods Eighty-two single-rooted premolars and an-terior teeth were prepared by using M3 machine with nickel-titanium file and randomly divided into six experimental groups(n=12)and two control groups(n=5).Group A1:single-cone technique(SC)+C-R;group B1:SC+iRoot SP;group C1:SC+GFB;group A2:single-cone with ultrasonic activation(SU)+C-R;group B2:SU+iRoot SP;group C2:SU+GFB;group D:positive control group,and group E:negative control group.Dye penetration length and lateral root ca-nal filling in each group were measured by dye penetra-tion test.A scanning electron microscope(SEM)was used to observe the interface between gutta pertscha,root canal sealer,and dentin wall.Dye penetration length was measured and analyzed by Kruskal-Wallis test,and data on lateral root canal filling were evaluated using Chi-square.Re-sults The dye penetration length in group A1 was lower than that in groups C1 and A2(P<0.05)but was not significant-ly different from the other groups(P>0.05).Lateral root canal filling was not significantly different among all groups(P>0.05).SEM showed that GFB was slightly better than C-R and iRoot SP in binding to gutta pertcha and dentin wall.Con-clusion GFB,C-R,and iRoot SP demonstrate excellent apical sealing ability.Under the conditions tested in this study,SU did not yield significantly improve the apical sealing ability of the three root canal sealers.关键词
