A supernumerary maxillary premolar: a case report

Abstract

Introduction: Supernumerary teeth are regarded as one of the most common dental anomalies. Occurrences may be single or multiple , unilateral or bilateral, and in one or both jaws. Incidences of supernumerary teeth are primarily found in permanent dentitions; however, they may rarely be encountered in primary dentitions as well. The presence of multiple supernumerary teeth is usually associated with certain conditions or syndromes such as cleft lip/palate, cleidocranial dysplasia (CD), Gardner's syndrome, Down syndrome, etc. Supernumerary teeth (hyperdontia) can be defined as any tooth or tooth structure that is in excess in the presence of 20 deciduous, or 32 permanent teeth in one individual. Aim: The aim of this article is to show clinical case with a supernumerary maxillary premolar, especially when there are other supernumerary teeth in one dentition without any records of present syndromes or genetic predisposition Case Presentation: The subject of this clinical study was an old patient, with complains of maxillary sinus pain. The intraoperative observations established that the supernumerary tooth was surrounded by bone tissue and no communication with the sinus cavity was observed. Results: Although no communication with the sinus cavity was observed, there were no complaints and complications after the extraction of the supernumerary tooth. The patient was called for a follow-up one week and six months after the extraction and had no complaints. Conclusion: Supernumerary teeth are not uncommon and their detection in most cases happens to be accidental, but the rare phenomenon of supernumerary premolars is of special research interest, especially when there are other supernumerary teeth in one dentition without any records of present syndromes or genetic predisposition.
