- Abstract
Carabelli's trait is defined as an addition tubercule with a different frequency on the mesiolingual surface of upper molars. This variation appears mostly in upper first molar and second deciduous molar, as less common in permanent second molar and as rarely in third molar. This trait seen mostly in Europeans represent different frequencies among several populations. Due to its high heritability value, this trait could be used to determine the differences among populations. The frequency of Carabelli's trait was investigated at a total of 390 individuals on upper first molars (MI) of 108 individuals, upper second molars (M2) of 143 individuals and upper third molars (M3) of 139 individuals from three ancient Anatolian populations. Cerebelli trait was recorded with 8 degrees according to ASUDAS (Arizona State University Dental Anthropology System). For the identification of differences across population, and sexes, Carabelli frequency that was recorded separately according to sides was used X2 test on SPSS 11.01 program. Carabelli frequency in Iznik population (59.0 %) was observed higher than İkiztepe (57.0 %) and Cevizoğlu Çiftligi (53.8 %) populations, but statistically this was not a significant difference. When Carabelli's trait was investigated according to its degrees excessive forms of Carabelli's trait (6 and 7) were higher at Iznik population than the other two groups. When the results of Carabelli frequencies were compared with MDD values of 30 non-metric traits on the crania of same populations, they are found similar. Although Carabelli's trait shows differences between sex at some populations, it is not a significant difference for Anatolian populations. In the same way, it has been reported by researcher that there was difference Carabelli's trait between right and left sides. In this study, a minor asymmetry (2,4 %) in upper M1 was observed. When the absent group was added to the present group, symmetry between sides was determined as 97,6 %. It was observed that the symmetry changes in M2 and M3. While the asymmetry is 4,4 % in M2, it increases in M3 (7,1 %). Due to this symmetry, it can state that this trait is less influenced by enviromental factors. Therefore, because of the mode of its inheritance, it can be used for the studies of biological dinstance. However, more significan results can be reached, when this traits is evaluated together with other morphological features in the studies biological distance.
