Case report: non-syndromic multiple supernumerary teeth localized by cone beam computed tomography

Abstract

Background: Supernumerary teeth are an infrequent developmental alteration that can appear in any area of the dental arches and which are often associated with several syndromes such as cleidocranial dysplasia or Gardner syndrome. Multiple supernumerary teeth in individuals with no other associated diseases or syndromes are very uncommon.

Case report: A 14-year-old male patient presented with 13 unerupted supernumerary teeth distributed in all four quadrants.

Treatment: After taking a cone beam computed tomograph (CBCT), surgical extraction was performed under general anaesthesia in two steps in order to minimize the risk of airway-constriction by haematoma.

Follow-up: Follow-up examination was uneventful. Further orthodontic treatment is planned which will secure the orthodontic alignment and correct occlusion.

Conclusion: Cone beam computed tomography is crucial for exact localization, for treatment planning, and for the surgical approach in cases of multiple supernumerary teeth.
