Abstract

Objectives: To compare the push-out bond strength of root fillings made with either 2Seal or TotalFill BC sealer after the additional instrumentation of oval canals with either the XP-endo Finisher (XP) or Self Adjusting File (SAF) systems.

Material and Methods: Mandibular premolars with single oval canal were collected for the study. Root canals were prepared with Reciproc R25 and were randomly divided into six groups (n=10), as follows: group 1, additional instrumentation with SAF and filling using 2Seal and gutta-percha (GP); group 2, additional instrumentation with SAF and filling using Total Fill BC and GP; group 3, additional instrumentation with XP and filling using 2Seal and gutta-percha; group 4, additional instrumentation with XP and filling using TotalFill BC and GP; group 5, canal filling with 2seal and GP without additional instrumentation; group 6, canal filling with Total Fill BC and GP without additional instrumentation. Each sample was sectioned horizontally into 1 mm thick slices at each thirds and push-out test was performed using universal testing machine. Three-way ANOVA and Tukey’s post-hoc tests were performed to compare groups.

Results: The bond strength values of the XP group were significantly higher than the values of the SAF and Reciproc groups (P<0.05). There was no statistically significant difference among the groups regarding the failure types.

Conclusion: Additional instrumentation applications of the XP for teeth with complex canal anatomy, such as oval-shaped canals, might increase the bond strength of different types of sealers
