Abstract

Abstract: Objective: To evaluate the sealing ability and marginal adaptability of mineral trioxide aggregate (MTA; Group A), iRoot BP Plus (Group B), and nRoot BP (Group C) in the treatment of perforation in vitro. Methods: Sixty-two teeth, which were access opened and prepared furcation perforations, were randomly divided into three experimental groups (A, B, C, n=18) and two controls (D, E, n=4). Following the repair procedure, four samples from three experimental groups were randomly selected to measure the gap between the pulpal floor and the repair material with a scanning electron microscope, and the other specimens were immersed in 1% basic fuchsine solution for 48 hours to evaluate the dye penetration under the stereomicroscope. Results: There was significant difference in the microleakage among three experimental groups (P<0.05). MTA had more dye penetration than iRoot BP Plus and nRoot BP. Under scanning electron microscopy, the gaps of both nRoot BP and iRoot BP Plus were smaller than that of MTA, and there was a statistically significant difference between three experimental groups (P<0.05). Conclusion: iRoot BP Plus and nRoot BP had better sealing performance and marginal adaptability when used to repair the furcation perforation.

Key words: MTA, bioceramics, perforation of pulpal floor, sealing
