Differences in microleakage between MTA and Biodentine™ as material for treatment of access perforation

Perforation is one of the most common complications in endodontic treatment and can result in significant negative effects. It occurs when practitioners are trying to create an access pathway to the pulp chamber. Contamination from the perforation site to the root canal decreases healing ability; therefore, perforation must be treated as soon as it happens. The aim of this study was to evaluate microleakage of Mineral trioxide aggregate (MTA) and Biodentine™ as materials for treatment of access perforation. Microleakage was evaluated by using a stereo microscope to assess methylene blue 1% solution penetration between the restoration material and the perforation site. The data was analyzed with the Kolmogorov-Smirnov test. Based on statistical analysis of the data, there is no significant difference in microleakage between MTA and Biodentine™ as a material for treatment of access perforation.
