The Aim: The aim of this cross-sectional study was to investigate the radiographic prevalence of selected developmental dental anomalies in the western region of Saudi Arabia.
Materials and Methods: A retrospective cross-sectional study of randomly selected 1019 digital orthopantomograms (OPGs) taken of patients who presented for treatment at the Faculty of Dentistry, Umm Al-Qura University, Saudi Arabia between 2013 and 2014. The OPGs were examined to investigate three categories of dental anomalies; number, shape and eruption.
Results: The prevalence of patients that exhibited at least one developmental dental anomaly was 55.7%. The most prevalent dental anomaly observed was impaction (48.1%) followed by dilacerations (33.5%), hypodontia (6.8%), microdontia (4%), macrodontia (2.8%), supernumerary (2.3%), germination (0.6%), taurodontism (1.7%), fusion (0.1%) and dens in dent (0.1%). No transposition case was detected.
Conclusion: The results of this study showed that one in two patients from the study sample has at least one developmental dental anomaly. The most prevalent dental anomalies were wisdom tooth impactions followed by dilacerations. The least prevalent anomalies were germination, fusion, and dens in dent. No any cases for teeth transposition were recorded.

Key words: Dental anomalies, Orthopantomograms (OPG), Hypodontia, Impaction.
