Abstract

Objective: Dental anomalies are abnormal morphological development of dentition during various periods of tooth development and
have an important role in the development of various kinds of malocclusions. If dental anomalies not diagnosed, they can make dental
and orthodontic treatment more difficult. So, orthodontists and the general dental practitioner must investigate patients carefully. The
objective of the current study was to determine the prevalence and distribution of dental anomalies in a sample of orthodontic patients
in Erbil city using orthopantomogram.
Methods: Four hundred fifty-eight orthopantomograms of orthodontic patients with age of 16-40 years evaluated to determine the
prevalence and distribution of the hypodontia, impaction, microdontia, and supernumerary tooth.
Results: 15.06% orthodontic patients: 21 males and 48 females had at least one dental anomaly. Impaction and hypodontia were the
most common dental anomalies with no significant difference between genders. Maxillary canines were more commonly impacted
tooth, whereas maxillary lateral incisors were the most common tooth agenesis among genders.
Conclusions: Impaction was the most prevalent dental anomaly, and maxillary canines were the most involved teeth and are in
agreement with many studies among various populations. The most frequently missing teeth were the maxillary lateral incisors.
However, mandibular 2nd premolar was the most common hypodontia in some studies.
