Management of Immature Permanent Teeth With Crown-Root Fracture: A Case Report With a 24-Month Follow-up

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 areasaffected by trauma in the mouth is maxillary central incisors.

A10-year-old boy fractured his maxillary central incisors. The fracture line involvedthe pulp,extended subgingivally on the palatal aspect invading the biologic width. The procedureused to manage this case included endodontic treatment of residual teeth,surgical extrusion tomove the fracture line above the alveolar bone. Finally,the teeth were restored with composite buildup.

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.
