A comparative evaluation of medicated calcium sulphate, hydroxylapatite, mineral trioxide aggregate (MTA) as barrier and their effect on the sealing ability of furcation perforation repair material--an in vitro study.
Artificial communication between the root canal system and supporting tissues of the tooth lowers the prognosis of the endodontic treatment. Studies have found that the second most common reason for failure association with endodontic treatment is root perforation. Hence a study was undertaken to evaluate the effect of calcium sulphate, hydroxylapatite and MTA as internal matrix and their ability on the sealing ability of the perforation repair material (GIC) on 70 recently extracted molar with non fused roots. MTA showed the least microleakage and best sealing ability and resin modified GIC when used alone without any internal matrix showed maximum microleakage and least sealing ability.
