Abstract
Summary: Objectives: Determine the correlation of the frequency and variability of three Non-metricdental crown traits (Carabelli cusp, protostylid and molar pattern cusp) between deciduous (um2/lm2)and permanent (UM1/LM1) teeth in mixed-dentition subjects. Materials and methods: A descriptivestudy was conducted to determine the dental morphology in mixed dentition stage of young subjects.The Arizona State University Dental Anthropology System ASUDAS and Grind and Sciulli Methods wereused as reference to compare frequency of dental traits in dental casts of 100 young individualsracially mixed. Results: A high expression of furrows and pits of the Carabelli cusp, a highfrequency of protostylid in degree 1 (foramen secum) and a expression of molar pattern cusp,revealed that the studied population received influences of the Mongoloid and Caucasoid dentalcomplexes. Correspondence on the traits expression among temporal and permanent dentition was alsoconfirmed. Bilateral symmetry and sexual dimorphism in the analyzed non-metric dental crown traitswere found. Key words: Dental anthropology. Dental morphology. Non-metric dental crown traits. Mixeddentition.
