Prevalence of Carabelli’s trait among Iraqi population [Salahdin-Tikrit]


Morphological features of dental study have significant importance in anthropological researches. Its provide numerous information on the dental variations within a specific population. this study is aiming to evaluate the Carabelli trait prevalence in the Iraqi population at province (Salahdin, Tikrit). 200 individuals aged 17-30 years (72 males and 128 females) were examined. A direct intraoral examination was performed. The Dahlberg classification system was dependent, and the Impressions were taken to compare the clinical data with the study casts. The obtained data were compared with the clinical data. The prevalence of the trait was (59.5%) with a slightly different distribution between both males and females. Grade I was the most frequent configuration of (40.6%) comparing to grade III that has least frequent of (2.3%). The trait results of this study have different frequency comparing to other regions in the world, and considerably very close to the Iranian and Saudi Arabia population.
