Abstract

A 49-year-old Black African male, originally of Nigerian origin, was referred by his dentist regarding a bad taste in the mouth. He was seen in a general restorative clinic at Barts and the London NHS Trust. Clinical examination did not reveal any relevant abnormalities. A panoramic tomography, however, showed the presence of multiple supernumerary teeth, which were located in the maxillary right and left premolar and molar regions, and the mandibular left premolar region. The family's history was non-contributory. The patient was unaware of the supernumerary teeth and, as far as he knew, there were no other members of his family with a similar problem.

Clinical Relevance: A decision regarding the appropriate management of supernumerary teeth should be considered carefully since surgical removal of the teeth may cause damage to adjacent structures, including bone. In this respect, it is interesting and rare to find multiple supernumerary teeth in individuals with no other associated diseases or syndromes elucidated by clinical and historical enquiry.

Article

Although the first report of supernumerary teeth appeared between AD 23 and 79, the aetiology of supernumerary teeth is still not clearly understood. They may occur singly, multiply, unilaterally or bilaterally, and in one or both jaws.

Multiple supernumerary teeth are usually associated with cleidocranial dysplasia, Gardner's syndrome and cleft lip/palate.1 It is, however, rare to find multiple supernumeraries in individuals with no other associated disease or syndrome.2

Interestingly, the maxillary region has the highest frequency of occurrence, being 12 times (66.7%) more likely to contain supernumeraries, followed by the mandibular premolar region with 4 times (22.2%), whilst the maxillary premolar and mandibular anterior regions have an occurrence rate of 5.6%. The conical and tuberculate types of supernumerary teeth were found in the midline region, whilst the supplemental supernumerary teeth were more in the mandibular premolar region with 12 (70.6%), followed by maxillary midline 4 (23.5%) and the lower incisor region (5.9%).3 In the literature, a ratio of 2:1 was reported in favour of males with supernumerary teeth when compared to females.4
