Influence of MTA powder handled with distilled water or phosphate buffered saline in push-out performance

Abstract

Objective: to investigated the bond strength of MTA powder handled with distilled water (DW) or phosphate buffered saline (PBS). Material and Methods: two horizontal cross-section were prepared in the root of fifteen incisors, followed by drilling of two canal-like holes on its axial surface. Holes were filled with MTA with DW or PBS. Load was applied until MTA displacement. Mann-Whitney and Friedman tests were selected to establish the influence of independent variables on push-out strength. Results: MTA handled with DW and PBS showed similar values (p>0.05). Conclusion: DW or PBS do not interfere in push-out bond strength of MTA.
