Abstract

Carabelli’s cusp is one of the non-metric dental traits that most commonly investigated. The highest frequency of this trait was Caucasian or Western Eurasia, but the frequency of this trait at the people who fall into the Sunda Pacific was not low. Identification was usually performed in adults and appeared to have not been done in children, whereas the database of dental traits at an early age was also required. To know the present of Carabelli’s cusp on Javanese at mixed dentition phases until the early phase of the permanent dentition. The sample was a model of the upper jaw, consists of 31 models of the Javanese boys in Surabaya aged 8, 10, and 12 years. The 93 models was observed 3 times by intra-observer to see Carabelli’s cusp on the mesiopalatal region of the permanent upper first molar. Then Carabelli’s cusp was divided into pronounced, weak, and none. In the group of children aged eight years, pronounced Carabelli’s cusp was 16.13%, weak Carabelli’s cusp was 25.8%, and no Carabelli’s cusp was 58.07%. In children aged ten years, pronounced Carabelli’s cusp was 12.9%, weak Carabelli’s cusp was 19.36%, and no Carabelli’s cusp was 67.74%. Whereas in children aged 12 years, pronounced Carabelli’s cusp was 22.58%, weak Carabelli’s cusp was 45.16%, and no Carabelli’s cusp was 32.26%. Carabelli’s cusp in the early phase of the permanent dentition is easier to observe.
