Abstract
Background: Dental anomalies (DA) are a group of dental developmental disturbances which appear during tooth formation manifesting themselves as an alteration in tooth number, shape, and size. Dental anomalies of number include hypodontia, mesiodens, supernumerary tooth, and odontoma.
Aim: To evaluate the prevalence and distribution of dental anomalies associated with tooth number in the radiographic archives of University Dental Hospital Sharjah, United Arab Emirates (UAE).
Methodology: Retrospective evaluation of 2000 Orthopantomogram (OPG) images were taken between January 2015 to December 2022. The OPG showing dental anomalies of number were further investigated for the availability of Cone Beam Computerized Tomography (CBCT). Multiple logistic regression analysis was performed to assess the influence of age and gender on the presence of supernumerary teeth, p
Results: The prevalence of DA in relation to tooth number was 3.8% (Hypodontia 0.1%, mesiodens 0.5%, odontoma 0.9% and supernumerary teeth 2.4%) in this study. Significant difference was noted only in the prevalence of supernumerary teeth between male (1.7%) and female (3.5%) (P=0.008).
Conclusion: The prevalence of DA in relation to tooth number in the present study was 3.8%. Prevalence, site of occurrence and gender distribution of DA in relation to tooth number in UAE residents were similar to the population in other parts of the world.
