Abstract

Objectives: 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).

Methods: Retrospective evaluation of 2000 orthopantomogram (OPG) images taken between January 2015 and December 2022. The OPGs showing dental anomalies of number were further investigated for the availability of Cone Beam Computed Tomography (CBCT). Multiple logistic regression analysis was performed to assess the influence of age and gender on the presence of supernumerary teeth; p < 0.05 was considered statistically significant.

Results: The prevalence of dental anomalies (DA) related to tooth number was 3.8% (hypodontia 0.1%, mesiodens 0.5%, odontoma 0.9%, and supernumerary teeth 2.4%). A significant difference was noted only in the prevalence of supernumerary teeth between males (1.7%) and females (3.5%) (p = 0.008).

Conclusions: The prevalence of DA in relation to tooth number in the present study was 3.8%. The prevalence, site of occurrence, and gender distribution of DA in UAE residents were similar to populations in other parts of the world.
