| ABSTRACT Introduction: Calcium silicate sealers have been widely used to do their bioactivity, but their effect on the fracture resistance of endodontically treated teeth is still unclear. Aim: This search compared the effect of calcium silicate sealers and resin sealer on the fracture resistance of dog’s root, using different irrigants. Materials and methods: Sixty-five incisors of six dogs were randomly allocated into three experimental (n=15), positive (n=15), and (n=5) negative control groups according to the type of sealer that was used for obturation; group A: BioRoot RCS, group B: TotalFill BC, group C: AH plus, group D: positive control prepared-unfilled and group E: negative control intact teeth. Each group was then classified into 3 subgroups (n=5) according to the final irrigation used; subgroup 1: 2.5% NaOCl, subgroup 2: 17% EDTA, subgroup 3: Saline. After three months of preparation, irrigation, and filling, dogs were euthanized, and teeth were extracted for assessment of root fracture resistance using Instronrsal testing machine. Two-way analysis of variance (ANOVA) was used to study the effect of sealer type, irrigant, and their interaction on mean fracture resistance. Bonferroni’s post-hoc test was used for pair-wise comparisons when ANOVA test is significant. The significance level was set at P ≤ 0.05. Results: There was no statistically significant difference between roots obturated with the three tested sealers after different irrigants and the negative control (intact roots) group. All showed higher statistically significant mean fracture resistance than positive control (prepared / unfilled) group. Conclusion: Root canal preparation decreases the fracture resistance of root canal treated teeth. However, obturation with all tested sealers increased the force values needed to fracture the filled samples when compared to unfilled ones. | ||
