Intraradicular reinforcement for traumatized immature teeth.

Immature necrotic teeth after trauma pose both endodontic and restorative challenges because of incomplete closure of the apex, and thin and weakened dentinal walls that make them prone to fracture. The use of light-transmitting plastic posts, in combination with adhesive materials, enable intraradicular reinforcement of flared canals, helping to rehabilitate fractured immature teeth and maintain a functional unit within the dental arch. The purpose of this paper is to present the case of a nine-year-old patient who had a complicated fracture of an immature anterior tooth, which was endodontically treated with mineral trioxide aggregate in the apical third. The dentinal root walls were successfully reinforced with composite resin and a light-transmitting glass fiber post, followed by the placement of a glass fiber composite post and a metal ceramic crown.
