Endodontic management of a long-standing horizontal mid-root fracture: case report in a young patient

Abstract

The purpose of this case report was to present the successful endodontic management of a long-standing horizontal mid-root fracture in a permanent maxillary central incisor. A 12-year-old boy with a history of traumatic injury sustained 15 months previously to the maxillary central incisor presented for treatment. Clinical examination revealed physiological mobility, pulp chamber exposed to the oral environment, and the buccal mucosa with a sinus tract in the area of the traumatized tooth. A radiolucent lesion at the fracture line and apical fragment with obliteration of the root canal space were observed radiographically. Conservative root canal treatment of the coronal segment was performed using calcium hydroxide as an intracanal dressing. The calcium hydroxide was replaced every 8 weeks for 10 months. A hard tissue barrier was observed after this period, and the coronal fragment of the root canal was filled. After 4 years, the tooth was asymptomatic and functional and no periapical lesion was observed.
