Abstract:

Dental traumatic injuries are highly prevalent among children and adolescents. Crown-root fractures of anterior teeth present difficulties for restoration. This case report describes the treatment of a complicated crown-root fracture of maxillary right lateral incisor with extensive loss of tooth structure and uncomplicated crown fracture of maxillary right central incisor in a young adult. The 15-year-old male patient was presented to Endodontic clinic with post-traumatic injury. After the mobile crown-root fragment of lateral incisor was removed, root canal therapy was performed in two visits. Calcium hydroxide was used as an intra-canal dressing. Root canal filling, glass fiber post cementation and adhesive tooth fragment reattachment were performed. Central incisor was restored with composite restoration. Early stage success was achieved with the observance of good functional and aesthetic outcomes. However the patient did not attend follow-up visits and returned after 14 months with secondary trauma which resulted fracture of the reattached part and minor fractures extending to middle root so the tooth was extracted. As it is crucial to retain the tooth to maintain space and to protect alveolar bone height, clinicians should always consider trying reattachment of tooth fragments. The case presented here is sufficient and effective in postponing fixed prosthetic restorations or implant treatments.
