Abstract:

Objective To investigate the clinical effect of fibrous root canal dowel internal fixation combined with composite resin adhesion in treatment of crown-root fracture of anterior teeth in children. Methods Eleven children (11 teeth) aged 11 to 14 with crown-root fracture caused by trauma of upper mandible medial incisor were selected. All were horizontal fracture or oblique fracture, and there was no longitudinal fracture and alveolar bone fracture. Patients received one-visit endodontics treatment after external fixation of the injured teeth, and were follow up for one week. The crown-root broken ends were restored with fibrous root canal dowel internal fixation combined with composite resin adhesion. Results Nine teeth were successfully restored, and were cosmetically and functionally resumed in short term. One patient failed due to lower palatal fracture line, with more wound hemorrhage and exudation. And the other patient failed due to consumption of hard food, which led to the loose broken ends. Conclusion Fibrous root canal dowel internal fixation combined with composite resin adhesion may be an ideal temporary restoration method in treatment of crown-root fracture of anterior teeth in children, which can resume cosmetics and function in short term and decrease loss in dental and periodontal tissues to the full extent.
