Abstract

Supernumerary teeth are extra teeth found in the dental arches in addition to the normal dental series, account for about 3% of the total dental anomalies. We are presenting the importance for the dental practice of the genetic study performed in the case of a patient presenting a supernumerary maxillary lateral incisor in the secondary dentition, an isolated, sporadic case, non-hereditary and non-syndromic dental anomaly, the consequence of a spontaneous, de novo mutation. The genetic study was performed by the Genetics Department, according to the ethical standards of scientific research and after acquiring the patient’s informed consent. The clinical and radiological examination of the patient was completed with the examination of the intra-oral photographs, the family history investigation, the genealogical tree, and the analysis of the studied family’s pedigree. The genetic research allows for the identification of their genetic or environmental etiology, the determination of the recurrence risk amongst descendants, as well as the specific observation of the affected families, to prevent complications of the supernumerary teeth.
