[Carabelli's tubercule in the Wolof ethnic group (Senegal)].
The authors study the Carabelli's trait in a Wolof population (Senegal). This morphologiest alteration is mainly present on the first permanent maxillary molar.


METHODS
195 left and right first molars of 102 individuals with one equal sex distribution were used. The morphological examination of 194 second maxillary molars (left and right) completed the study.


RESULTS
They show a frequency of 11.8% traits, either individualized (6.7%), either hypertrophic (5.1%), with a predominance of attenuated (37.4%) or absent formations (50.8%), as well as a sexual dimorphism (19% of individualized or hypertrophic traits in the female population, versus 4.2% in the male). The presence of an attenuated trait (grooves and pits) on the second molars follows also a repartition in favor of the female population (24% versus 4.2%).
