Abstract
A crown-root fracture is defined as a fracture which involve enamel; dentin and root cementum with or without the involvement of pulp. If pulp is involved it is known as complicated crown-root fracture. It is usually oblique in nature involving both crown and root. In this case report we have a case of 20 year old female with oblique complicated crown-root fracture and an irreversible pulpitis of maxillary left canine. In this case endodontic therapy followed by reattachment of fractured fragment with a prefabricated fiber post followed by PFM crown was the treatment plan for the patient and patient responded successfully to treatment..
Highlights
The most commonly involved teeth in dental trauma are maxillary incisors
During dental trauma sometimes a complicated crown-root fracture occurs which is characterized by a fracture that involve enamel, dentin, cementum with pulpal involvement
Treatment plan selected for patient was root canal treatment followed by reattachment of the crowns by using fiber-reinforced post followed by PFM crown
Summary
The most commonly involved teeth in dental trauma are maxillary incisors. During dental trauma sometimes a complicated crown-root fracture occurs which is characterized by a fracture that involve enamel, dentin, cementum with pulpal involvement. Crown-root fractures extending apically towards both the gingival margin and the alveolar crest pose a great challenge. 1–3 Gingivectomy, osteotomy, orthodontic extrusion, surgical extrusion, intentional replantation or extraction are various methods for the management of complicated crown-root frcture. 4 Whenever there is no or minimal invasion of the biological width and fragment of tooth is intact, reattachment of fractured fragment of tooth by fiber post is most favourable treatment procedure.
