Non-syndromic multiple impacted supernumerary teeth: two case reports

Abstract

Multiple impacted teeth may be related to syndromes and metabolic disorders. In some cases, however, impaction of multiple teeth is not accompanied by any other disorder or syndrom. Hyperdontia or supernumerary teeth without associated syndromes is a rare phenomenon, as supernumerary teeth are usually associated with cleft lip and palate or other syndromes such as Gardeners syndrome, cleidocranial dysplasia and trichorhinophalangic syndrome. The aim of this paper is to demonstrate that asymptomatic multiple impacted ectopic teeth are not always associated with a syndrome or a disorder. A 15-year old male patient attended our clinic with a chief complaint of irregular teeth and unaesthetic smile. In intraoral examination irregular and amorphous erupted teeth were noticed. On routine radiographical examination, impacted supernumerary teeth were noticed in maxilla and mandible. A 37-year old male patient attended our clinic for routine examination and radiographic examination revealed supernumerary and amorphous teeth in mandible and maxilla. In our cases, medical and family history and extraoral examination were not suggestive of any syndrome or metabolic disorder. A general physician was consulted who confirmed that there was no associated syndrome. The supernumarary teeth were surgically extracted. The 15 year old patient who was suffering from irregular teeth was directed to orthodontics clinic. In conclusion, routine radiographic examination may reveal multiple impactions, even if there is no absence of teeth. The etiologic factor of multiple impacted supernumerary teeth is still not clearly known, especially in cases without any syndrome. However, additional examinations may be necessary to exclude systemic and metabolic conditions.
