A scanning electron microscopic study evaluating the sealing ability of MTA, BiodentineTM, and new light-cure MTA used for furcal perforation repair.

Background: To evaluate and compare the sealing ability of Mineral trioxide aggregate (MTA), BiodentineTM and light cure MTA used for the repair of furcal perforations using scanning electron microscope (SEM).

Material And Methods: The study sample comprised 45 extracted mandibular molars. The teeth were embedded in modeling wax.
