Surgical retrieval of displaced mandibular third molars: A five-year experience with 16 cases

Abstract

BACKGROUNDThis study aimed to report the surgical retrieval of iatrogenic displaced mandibular third molars using Computed Tomography CT and Cone Beam Computed Tomography CBCT as pre-surgical diagnostic imaging. MethodsSixteen patients were referred to the Oral and Maxillofacial Department, Faculty of Dentistry, XXXXX University for surgical retrieval of displaced third molars. Patients consented and thorough clinical assessment and radiographic examinations were done using either CT or CBCT scans before the standard surgical procedure to retrieve the displaced teeth. It was intended for all patients to have their displaced teeth or root fragments retrieved using an intra-oral approach while under general anesthesia. Results7 (43.75%) third mandibular left molars/root fragments and 9 (56.25 %) third mandibular right molars/root fragments were retrieved. There was no statistically significant difference regarding swelling between the two CT and CBCT groups (P> 0.05). One patient in the CT group and three patients in the CBCT group experienced lingual nerve paresthesia which was resolved after three months. ConclusionsCT and CBCT scans are crucial diagnostic tools for pre-surgical evaluation and planning for the displaced mandibular third molars. CT provides clearer images and enables easy pre-surgical assessment.
