Aim: To study the prevalence and the most common of the developmental dental anomalies in dental students (2018-1019).
Material and methods: The dental students in the collage of Dentistry/Baghdad university were included in this study, 600 students were clinically and radiography examined and assessment of the dental anomalies was carried on which included the number of anomalies, shape and positions of the anomalies.
Results: In the current study, 250 dental students had a dental anomalies among 600 dental students that were examined, the highest percentage of the dental anomalies were recorded in males than in females, the highest percentage was recorded in 23 years old (36%) followed by 22 years old (28.8%), and the lowest percentage was recorded in 18 years old (1.2%). Also the highest percentage was recorded in number of anomalies (33.2%) followed by acquired anomalies (30.8%) and the lowest percentage was recorded in the shape of anomalies (8.8%) and the congenital missing of the second premolar recorded as the highest percentage (36.3%) than other number of anomalies followed by the congenital missing of the lateral incisor (24%) and the congenital missing of the lower incisor recorded the lowest percentage (12%). Also the positional anomalies showed that Impaction of the third molar recorded higher percentage (57.3%) than the impaction of the upper canine (42.7%). Peg lateral recorded higher percentage (63.6%) than dens evagination, for the acquired dental anomalies erosion recorded lowest percentage (36.3%) than attrition anomalies.
