Treatment of a horizontal root fracture using MTA: 2- year follow-up

Horizontal root fractures are rare when compared to other types of injuries, with a reported incidence rate ranging between 0.5%-7.0%. Fixation of teeth with splints has been recommended as the conservative treatment for horizontal root fractures, given that the pulp usually remains vital in such cases and spontaneous healing with no treatment has been reported in the literature. However, further treatment, such as root canal treatment, can be necessary when the tooth shows signs of pathology. An 11-year-old boy was referred with a chief complaint of traumatized maxillary anterior tooth. Horizontal root fracture was determined in the case and the tooth was treated by using MTA. After 24 month clinical and radiographic follow-up there were no pathological symptoms. Filling the entire root canal of the coronal fragment with MTA and giving a chance to the apical fragment to heal spontaneously is an appropriate solution for teeth with horizontal root fractures.
