The Prevalence of Dental Anomalies in the Western Region of Saudi Arabia

Abstract

Objective. The aim of this cross-sectional study was to investigate the prevalence of dental anomalies that could be a cause of malocclusion in the western region of Saudi Arabia. Materials and Methods. A retrospective study of 878 digital orthopantomograms (OPGs) taken of patients, age ranging between 12 and 30 years, who presented to treatment at the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia between 2002 and 2011. The OPGs and dental records were reviewed for congenitally missing teeth, supernumerary teeth, impactions, ectopic eruption, transposition, germination, fusion, dilacerations, taurodontism, dens in dent, and any other unusual conditions that can be assessed with OPG. Results. The prevalence of patient that exhibited at least one dental anomaly was 396 (45.1%) patients. The prevalence of congenitally missing teeth was 226 (25.7%), impacted teeth 186 (21.1%), dilacerated teeth 10 (1.1%), supernumerary teeth 3 (0.3%), odontoma 1 (0.1%), and taurodontism was also 1 case (0.1%) of the total radiographs reviewed. Conclusions. Congenitally missing teeth were found to be the most prevalent anomaly (25.7%), and the second frequent anomaly was impacted teeth (21.1%), whereas root dilacerations, supernumerary teeth, and taurodontism were the least frequent anomalies (1.1%, 0.3% and 0.1%, resp.).

Association between dental anomalies and malocclusion in Brazilian orthodontic patients

“…This study found a significant prevalence of developmental dental anomalies in Brazilian orthodontic patients, with high prevalence in females, similar to the results found by other authors (5,6,13,19). Hypodontia was observed significantly more in women; other authors have also reported prevalence of microdontia in females, while hyperdontia and macrodontia were more frequent in males (13).…”

“…The patients' age ranged from 7-42 years old, with most of the dental anomalies diagnosed between 11 and 20 years, and this result was similar to that found in the literature (5,13,19). The time of tooth formation may interfere with the diagnosis of each anomaly.…”

“…As opposed to agenesis, hyperdontia had a higher prevalence than that found in the literature (19,31). The first lower premolars were the most affected teeth, but this result is controversial.…”

“…However, the literature has conflicting results (5,6,8,19), perhaps explained by the different populations studied. Regarding the tooth size, microdontia was the most frequent anomaly, and the upper lateral incisors were the most affected teeth, in line with the findings of Guttal et al (21).…”

Prevalence of Dental Anomalies in Odisha Population: A Panoramic Radiographic Study

“…7 These anomalies may involve or arise in a single tooth or may be a part of systemic disorder or a syndrome that arise generalized to involve all the teeth. 8 Review of the literature has shown varying data on the prevalence of these DAs. The discrepancies in the data may be attributed to racial differences, different sampling techniques, and different diagnostic criteria.…”
