Mineral trioxide aggregate root canal filling of traumatized immature tooth

Abstract

An 8-year-old female patient reported to the dental clinic seeking a help to save her traumatized maxillary left central incisor. The tooth had been treated with a temporary filling by a general dentist. The coronal tooth structure was intact, discolored, and a temporary filling was placed on the access opening. She gave a history of trauma about 3 years back. An intraoral periapical radiograph revealed an open apex and dentin bridge in the middle of the root canal. The root canal and the access opening were filled with very poor filling. The tooth was managed successfully by conservative means using intracanal calcium hydroxide as an intracanal medicament, followed by mineral trioxide aggregate (MTA) filling. The access opening was filled with glass ionomer and composite resin restoration. One year and 6-month follow-up demonstrated a clinically asymptomatic and adequately functional tooth, with radiological signs of apical regeneration.
