Abstract

Background: Palatally impacted supernumerary teeth in the anterior maxilla can interfere with permanent tooth eruption and lead to complications if not properly diagnosed and treated. Cone-beam computed tomography (CBCT) is a modern imaging modality that enables precise assessment of tooth position and anatomical relationships. Objective: To describe the morphology, position, and complications of anterior palatal supernumerary teeth on CBCT, and to evaluate surgical outcomes. Subjects and Methods: A cross-sectional descriptive study was conducted on 35 patients aged 6–30 years with anterior palatal supernumerary teeth who underwent surgery at Hanoi Medical University Hospital (July 2024 – July 2025). Data from CBCT and postoperative follow-up were collected and analyzed using SPSS 16.0. Results: Male patients accounted for 71.4%. The most common orientation was inverted (51.4%), with teeth located palatally, at or below the level of the central incisor roots. Delayed eruption of permanent teeth was the most frequent complication (21.95%), while dentigerous cysts were rare (4.88%) but associated with poor outcomes. Postoperative pain and swelling decreased markedly after 3 days, with no significant differences observed between surgical approaches. Conclusion: CBCT plays a vital role in the evaluation of palatally impacted supernumerary teeth. Surgical outcomes were favorable when appropriate indications were applied and no severe complications were present.
