【 摘 要 】
Aims: The aim of this study is to evaluate the role of three different intraorifice barrier materials on resistance to fracture of obturated teeth with seal-apex sealer. Subjects and Methods: Eighty extracted human single-rooted mandibular premolars were decoronated to approximately similar dimension, and prepared and obturated with gutta-percha and seal-apex sealer. For the placement of different intraorifice barrier materials, the coronal 3-mm gutta-percha was removed except for the control group. The specimens were divided into four groups ( n = twenty) on the basis of the intraorifice barrier material used. Group I: Mineral trioxide aggregate (MTA), Group II: Cention N, Group III: Nanohybrid composite, Group IV: Control, Fracture resistance of the specimens was tested. Statistical Analysis Used: It was done by the statistical software SPSS version 16.0. One-way ANOVA followed by Tukey's HSD test and independent t -test was used. Results: Fracture resistance of endodontically treated tooth was significantly affected by the type of intraorifice barrier used ( P < 0.001). Conclusions: The use of nanohybrid composite significantly improved fracture resistance followed by cention N and MTA as compared to the control group.
