CAMMARATA-SCALISI, Francisco; AVENDANO, Andrea  and  CALLED, Michele. Main genetic entities associated with supernumerary teeth. Arch. argent. pediatr. [online]. 2018, vol.116, n.6, pp.437-444. ISSN 0325-0075.  http://dx.doi.org/10.5546/aap.2018.437.

Supernumerary teeth represent a common human dental anomaly, defined as presence of extra teeth-more than the normal number foreseen in primary or permanent dentition. The prevalence has been reported between 0.2 to 3%, and is more frequent in males than females. The etiology is heterogeneous, highly variable and most of the cases are idiopathic. However, the presence of multiple impacted or erupted supernumerary teeth is rare and associated with some genetic syndromes: cleidocranial displasia, familial adenomatous polyposis, trichorhinophalangeal syndrome type I, Rubinstein-Taybi syndrome, Nance-Horan syndrome, Opitz G/BBB syndrome, oculofaciocardiodental syndrome and Robinow syndrome (autosomal dominant). The supernumerary teeth should be considered in order to possibly diagnose these entities with the aim of offering an interdisciplinary management and treatment, as well as offer adequate family genetic counseling.
