Effect of Retreatment on the Push-out Bond Strength of MATA Fillapex and AH-plus Sealers

English Abstract

Introduction: The aim of the present study was to evaluate the effect of retreat retreatment on the bond strength of MTA Fillapex and AH-plus sealers. Materials and Methods: The root canals of 80 human mandibular Pre molars were prepared with ProTaper rotary files and randomly divided into two groups. The root canals in group A and B were obturated with gutta-percha and MTA Fillapex and AH-plus sealers, respectively. The teeth in both groups were randomly divided into two subgroups. In subgroups A1 and B1 no retreatment was carried out; however, in subgroups A2 and B2 retreatment was carried out with rotary files and solvent. After two weeks of incubation, four 2-mm slices were prepared from each tooth for push-out test. Data were analyzed with ANOVA test. • Results: The results showed significant differences in mean bond strength values between the two sealers. Comparison of the mean bond strength values in the study subgroups did not reveal significant differences, irrespective of the sealer type (P=0.3). • Conclusion: AH-plus sealer exhibited a higher bond strength compared to MTA Fillapex. Retreatment using rotary files and solvent did not exert a significant effect on the bond strength of sealers under study.
