A rare case of an immature incisor with horizontal root fracture traumatized at the time of eruption

Abstract

Dental trauma resulting in root fracture is a rare condition that affects up to 7% of permanent teeth, and injury to immature teeth is even rarer. This case report aimed to show the prognosis of a horizontal root-fractured immature maxillary incisor traumatized at the time of eruption. Because of an accident, a 6-year-old boy was referred to our clinic with horizontal root fracture of the permanent maxillary left central incisor associated with an extrusive luxation. The coronal segment was repositioned, and a dental splint was applied for 7 weeks. After 48 months, clinical examination revealed a positive response to electrical pulp testing and an absence color change of the tooth. Continuation of root development and calcification of the coronal pulp space was observed radiographically. It was concluded that fixation of teeth is a conservative treatment for immature teeth with horizontal root fractures, resulting in the pulp vitality and spontaneous healing with no other treatment.
