Prevalence of Dental Anomalies in a Sample of Orthodontic Patients in Erbil City

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.
