Abstract
A 44-year-old male was referred to the Department of Orthodontics at Manchester Dental Hospital. He presented with pain from his heavily restored, lower right second premolar, which had an apical supplemental tooth, visible radiographically. The dentist queried whether the second premolar tooth could be extracted and the supplemental tooth aligned in its place. Clinical examination revealed no relevant abnormalities. The family and medical history were non-contributory. Panoramic tomography revealed multiple supplemental supernumerary teeth in the canine and premolar regions. Cone beam computed tomography and multidisciplinary team input were required to plan the treatment for this unusual case.
CPD/Clinical Relevance: These findings highlight the management and treatment options for a case of non-syndromic, multiple supernumerary teeth. Consideration must be given to the risk of damage to adjacent structures if surgically removing supernumerary teeth, and the risk that supernumerary teeth may be ankylosed and not amenable to alignment within the arch.
Article
Supernumerary teeth can be single or multiple, unilateral or bilateral in distribution and can occur in one or both jaws. In the permanent dentition, there is a reported prevalence of 0.1–3.8%.1,2,3 Supernumeraries are classified by their morphology (conical, tuberculate, supplemental, odontome) or by their location (mesiodens, paramolar, distomolar). Supplemental supernumerary teeth are defined as those teeth additional to the normal series. They resemble teeth of the normal series and appear at the end of the series.1 The most common supplemental tooth is the permanent maxillary lateral incisor.1
Cases of one or two supernumerary teeth are known to most commonly affect the anterior maxilla. Presentations of multiple supernumerary teeth with no associated systemic conditions or syndromes are uncommon.2 In these cases, supernumerary teeth occur predominantly in the premolar areas, followed by the molar and anterior regions, respectively.2 They are most commonly found in mandibular premolar region.2
