Abstract
Aim: The purpose of this study is to assess the prevalence of erupted supernumerary teeth among a
group of Egyptian children aged from 6-15 years old attending the Outpatients’ clinic of Pediatric
Dentistry and Dental Public Health Department, Faculty of Dentistry, Cairo University.
Methodology: Six hundred and four patients who fulfilled the eligibility criteria were examined from
the Outpatients’ clinic of Pediatric Dentistry and Dental Public Health Department, Faculty of Dentistry,
Cairo University, during the period from May to July 2019. Children were examined clinically only and
evaluated for the presence of supernumerary teeth and their type, location, shape and associated
complications.
Results: Out of the examined 604 patients, 13 (2%) children had supernumeraries with a male: female
ratio (1.6:1), mesiodens was the most prevalent type (69%) followed by supplemental (31%); no
paramolars or distomolars were found. All supernumeraries were located in the anterior maxilla. The
most common complication was rotation of the adjacent teeth.

Conclusion: The prevalence of hyperdontia in Egyptian children is relatively high with males being
more affected than females.
The mesiodens is the most prevalent type of supernumerary teeth and rotation of the adjacent teeth is
the most common complication due to mesiodens prevalence.
