<strong>Introduction:</strong> Dentin bond strength of the perforation repair materials is one of the effective factors on the materials sealing ability and success of the treatment. The aim of this study was to evaluate the effect of phosphate-buffered saline (PBS) on the push-out bond strength of White Mineral Trioxide Aggregate (WMTA) in the presence of blood contamination in simulated furcation perforations. <br /><strong>Materials and Methods:</strong> This study was performed in Dental and Periodontal Disease Research Center in Tabriz Dental Faculty with the ethics code of IR.TBZMED.REC.B1396.819 in 2017.
