Aim: A maxillary left central incisor had been traumatised and undergone incorrect repositioning, causing apical fenestration of the cortical bone and patient discomfort. The aim of this case report was to evaluate the use of cone beam computed tomography (CBCT) in the diagnosis and treatment evaluation of lateral luxation injuries.
Materials and methods: CBCT was used to accurately image and diagnose the lateral luxation. The tooth was root canal treated, orthodontically repositioned and aesthetically restored with resin composite.
Results: Root canal treatment resolved the periapical pathology, and orthodontic treatment brought the tooth back into an anatomically appropriate position, with regeneration of labial cortical bone and complete resolution of patient discomfort. The 15-month follow-up was uneventful and the tooth was in good condition, both clinically and radiographically.
Conclusion: CBCT providing detailed three-dimensional images of teeth and surrounding tissues was a promising tool for the management of lateral luxation injury.
