Intractable treatment of inflammatory internal root resorption by fortifying with mineral trioxide aggregate and fibre post

This article describes a case report where mineral trioxide aggregate (MTA) and fibre post were used for nonsurgical endodontic management of internal root resorption in a 53-year-old woman. Internal resorption is a relatively rare phenomenon leading to destruction of intraradicular dentine and dentinal tubules. Thorough cleaning and shaping of the root canal space and the resorptive defect was achieved by mechanical instrumentation, irrigation, and interim calcium hydroxide dressing. The root canal apical to resorptive defect was obturated with gutta percha, whereas resorptive defect was reinforced using MTA and fibre post. Follow-up intraoral periapical radiographs at 18 months showed adequate repair of the resorption and the tooth remained asymptomatic.
