Rehabilitation of fractured nonvital immature tooth by nonsurgical treatment and post and core restoration: A case report and literature review

Nonvital immature permanent tooth presents several challenges to a clinician in performing conventional endodontic therapy due to the lack of apical constriction and thin root walls. Apexification has been serving as the gold standard therapeutic modality for managing nonvital teeth with wide-open apex. The present case report demonstrates the successful rehabilitation of fractured immature nonvital permanent tooth of a healthy 8.5-year-old male patient by apexification procedure using the premixed mixture of calcium hydroxide and iodoform with vehicle of silicone oil (Metapex). The dental procedure resulted in favorable treatment outcomes with Frank's Type-1 apical closure of root and optimum periapical healing within comparatively shorter duration. Subsequently, fractured crown was successfully restored for function and esthetics using fiber-reinforced post and core and composite restoration. In follow-up visits, the patient was found asymptomatic and satisfactory with the treatment results.
