Abstract
Pulp revascularization is the traditional protocol for treating immature necrotic teeth; however, it is not the usual management practice for traumatized teeth with horizontal root fracture. This is a case report of an 11-year-old patient subjected to trauma that occurred four years prior to treatment. The trauma led to horizontal root fracture in tooth #11, and the immature tooth #21 became necrotic with periapical radiolucency. Both teeth were treated with revascularization procedures. Each tooth was disinfected with triple antibiotic paste and a coronal seal using mineral trioxide aggregate. During the eight-year follow-up using periapical radiograph and cone beam computed tomography, tooth #21 showed periapical repair with apical closure. The fractured rooted tooth #11 was functional and asymptomatic, with evidence of bone growth inside the fracture line. From this case outcome, revascularization can be a successful treatment modality for traumatized teeth that have either root fracture or necrotic open apex.
