Abstract
The aim of this article was to review the literature on supernumerary teeth, analyzing their prevalence, etiology, diagnosis, treatment and possible complications. An electronic search was made in the Pubmed-Medline database up to January 2014 using the key search terms “multiple supernumerary teeth” (n=279), “prevalence supernumerary teeth” (n=361), and “supernumerary teeth” (n=2412). In addition to the articles initially identified, others were included in the review proceeding from a manual search and from any references considered of relevance. Supernumerary teeth are those that exceed the normal dental formula. They are more common in men, more common in the upper maxilla, and more prevalent in permanent dentition. Complications associated with supernumerary teeth include dental impaction, delayed eruption, ectopic eruption, overcrowding, spacing anomalies and the formation of follicular cysts. The treatment of supernumerary teeth depends on their type, position, and possible complications, detected clinically and radiographically. No clear consensus exists as to the best time to extract unerupted supernumerary teeth. Key words:Hyperdoncia, supernumerary teeth, impacted teeth, treatment, permanent teeth, deciduous teeth.

Summary
Supernumerary teeth are those that exceed the normal dental formula. This phenomenon is known as hyperdoncia and can occur in solitary or multiple form, may be unilateral or bilateral, and affect one or both maxillas (1). These teeth are more prevalent among men than women in a proportion of 2:1. The prevalence of supernumerary teeth is 0.3-0.8% in deciduous dentition and 1.5-3.5% in permanent dentition (1,2). Rao and Chidzonga (3) state that the etiology of supernumerary teeth is multifactorial, a combination of environmental and genetic factors. Complications associated with supernumerary teeth include impaction, delayed eruption, ectopic eruption, e414
