Abstract
Objectives: The main purpose was to determine the occurrence of pulp necrosis (PN) of teeth retained at the mandibular fracture site. An additional purpose was to investigate whether perioperative use of dexamethasone increases the risk of PN. Patients and methods: A follow-up study on 24 adult dentate patients with mandibular body, symphysis or parasymphysis fracture. These patients had been selected from a larger cohort who had participated in a randomized study of maxillofacial fractures and dexamethasone. All patients who were suspected of having a need for endodontic treatment were evaluated by an endodontist. Results: PN was diagnosed in six patients (25.0%) in one or two teeth. Of a total of 33 teeth situated in the fracture line, six (18.2%) were diagnosed as having PN. PN was more common in teeth in which the fracture line ran through the apex (21.7%) than in those in which the fracture line was in contact with the tooth cranially to the apex (10.0%). The association between PN and dexamethasone was not significant. Conclusion: PN is common after mandibular fractures, particularly when the fracture line runs through the apex of the tooth. Use of short-term, high-dose dexamethasone perioperatively did not significantly increase the risk for PN.
