| Abstract | ||||
| The purpose of this study was to evaluate the fracture resistance of endodontically treated teeth with two obturating techniques supported with different post systems.A total of 90 sounds freshly extracted sound human single rooted teeth were included in the present study. The teeth were prepared by using the crown-down technique. The prepared specimens were divided randomly into three main groups (30 specimens each) .Group A1 used Titanium post),Group A2 used Glass fiber post), and Group A3 used Cast post. Each main group was divided into two subgroups (15 specimens each ) according to the obturation techniques .Subgroup B1 used lateral condensation technique, and Subgroup B2 used Thermo plasticized injectable technique. Each subgroup was further subdivided into three minor subgroups each composed of5 specimens .Subdivision S1 Post immediately placed after obturation, S2 (One month), and S3 (Three months). Failure loads were measured under a static loading. The results of fracture resistance of this study showed that at Immediate, 1 month, and 3 months; no statistical significant difference between vertical and lateral obturation technique. Post types showed that there were statistically significant differences in both obturation techniques. Conclusions: The Glass fiber post was more fracture resistance followed by Titanium post, then Cast post. | ||||
