Abstract
Background: Crown root fractures are usually caused by severe horizontal trauma, involving enamel, dentine, and cementum, and continue down to the gingival margin. One of the most common areas affected by trauma in the mouth is maxillary central incisors. Case Presentation: A10-year-old boy fractured his maxillary central incisors. The fracture line involved the pulp and extended subgingivally on the palatal aspect invading the biologic width. The procedure used to manage this case included endodontic treatment of residual teeth and surgical extrusion to move the fracture line above the alveolar bone. Finally, the teeth were restored with composite build-up. Conclusion: During 24-month follow-up period, the teeth did not show any signs of root resorption. Therefore, surgical extrusion is recommended as a treatment option for crown/root fractures.

Summary
The oral region comprises only 1% of the total body area, oral injuries account for 5% of physical injuries of all ages. ► Crown root fractures are usually caused by severe horizontal trauma, and continue down to the gingival margin. Surgical extrusion is recommended as a treatment option for crown/root fractures. The chief complaints of the patient were pain and fractures of anterior teeth (Figure 1). According to his parent’s report, he had a motorcycle accident two month ago. Due to the incomplete development of roots and the time elapsed since the injury, the prescribed treatment plan was the apexification of teeth with MTA plug (Figure 4). Surgical extrusion was performed for definitive treatment and reconstruction of the coronal segment because the palatal portion of the fracture line continued down to the gingival margin and was approximately 1 mm below the alveolar crest.
