Aim: The study of dental morphological features is important in anthropological researches, because it can provide information on the dental variations within a specific population. The aim of this study was to evaluate the prevalence of Carabelli trait in Iranian adolescents. Subjects and Methods: In this descriptive study, 500 individuals (aged 15-49 years) were examined. Direct intraoral examination was done, morphological details of the crown, and sex of the subjects were recorded and Dahlberg classification system was used. Hydrocolloid impressions were taken and the study was repeated on the dental casts. The resultant data were compared with the clinical data. Descriptive statistics and Chi-square tests were used for data analysis (α = 0.05). Results: The prevalence of the trait was 96.6%, with significantly different distribution between males and females. Class 6 was the most frequent configuration (28.4%) and Class 1 was the least frequent (6.2%). Conclusions: The frequency of the trait was higher than that in other reports, but nearly similar to that of European groups.
