ABSTRACT
BACKGROUND: Irregularities in the number of teeth can also occur in deciduous and in permanent dentition. OBJECTIVE: The aim of this article is to report the case of a seven years old child and a 27 years old male patient affected by a numeric dental anomaly. METHODS: This paper has shown the pathologic condition characterized by the presence of supernumerary tooth (mesiodens) and supernumerary canine as well as supplementary premolars in a non-syndromic patients. Clinical and instrumental examinations were made to perform a correct orthodontic examination and diagnosis. A young patient was affected by numeric dental anomaly in the upper jaw. An adult patient was affected by numeric anomaly in both jaws, supplementary premolars in lower jaw and a supernumerary canine in lower and upper jaw. DISCUSSION: The aim of surgical-orthodontic treatment was extraction of the erupted supernumerary teeth to obtain the physiologic eruption and placement of the permanent ones. CONCLUSION: Therapy of supernumerary/ supplementary teeth is the extraction. But also, an excess tooth in the dentition can be left as a replacement tooth, due to a previously lost permanent tooth from the dentition, if its biological value and potential is sufficient to complete the dentition both functionally and aesthetically.
