title: Horizontal root fracture accompanied by luxation of coronal fragment in a maxillary central incisor: a case report.
abstract: Root fracture injuries affect up to 7% of permanent teeth. This type of injury is rarely seen in teeth with open apices and depending on the fracture site, the prognosis is good. This case report describes a horizontal intra-alveolar root fracture in the middle third of a maxillary central incisor associated with an extrusive luxation of the coronal segment and its treatment in a 6-year-old girl. The patient was observed under a regular follow-up regime. After 2 years, clinical examination showed normal tooth color and position, with a positive response to the pulp test.
