Abstract

OBJECTIVES
Fast-setting pozzolan cement (Endocem, Maruchi) was recently developed. The aim of this study was to investigate the effects of various root canal irrigants on the washout of Endocem in comparison to the previously marketed mineral trioxide aggregate (ProRoot; Dentsply) in a furcal perforation model.
MATERIALS AND METHODS
ProRoot and Endocem were placed into acrylic molds on moist Oasis. Each mold was then immediately exposed to either physiologic saline, 2.5% sodium hypochlorite (NaOCl), or 2% chlorhexidine (CHX) under gentle shaking for five minutes. Washout testing was performed by scoring scanning electron microscope (SEM) images.
RESULTS
Endocem exhibited higher washout resistance compared to ProRoot, especially in the NaOCl group.
CONCLUSIONS
These results suggest that Endocem can be considered a useful repair material for furcal perforation, especially in a single-visit scenario.
