Abstract

The aim of the study is to investigate the prevalence and gender distribution of selected dental anomalies in an Iranian orthodontic population. This is a retrospective review of panoramic radiographs of 1590 subjects investigated for frequency of selected dental anomalies. Differences in the frequency of each dental anomaly by sex were analyzed using the Pearson chi-square test. 12% of the patients showed at least one dental anomaly. The distribution by sex was 40 males (13.1%) and 150 females (11.5%). Hypodontia is the most common developmental dental anomaly in the Iranian orthodontic patients, followed in decreasing order by ectopic eruption.

Key words: Dental anomalies, prevalence, orthodontics.
