I denti sovrannumerari: revisione della letteratura

Objectives. The aim of this study was to evaluate the incidence and prevalence of supernumerary teeth in the population and to analyze possible treatment options. Materials and methods. The literature review was based on a search conducted in the US National Library of Medicine's PubMed database for articles published since 1966. Results and conclusions. Our review of the literature indicates that the incidence and prevalence of hyperdontia is higher when one considers permanent rather than deciduous teeth, and in general males are more frequently affected than females. Multiple supernumerary teeth can be associated with cleidocranial dysostosis, cleft lip or cleft palate, Ehlers-Danlos syndrome, Gardner's syndrome, and Fabry-Anderson syndrome. The mesiodens is the most common supernumerary tooth. Fourth molars are also fairly common. Hyperdontia is known to cause malocclusion. Different treatment options are available for this condition, and a specific treatment plan should be drawn up for each patient.
