Objective: To analyze the permanent teeth through mesodistal and vestibulo-palatal (vestibulo-lingual) dental diameters and Angle's molar classification to determine mean, sexual dimorphism, bilateral symmetry and population biological similarities in a group of Afro-descendants from the township of El Hormiguero, in Cali, Colombia. Materials and methods: Descriptive study that analyzed the mesodistal and vestibulo-palatal (vestibulo-lingual) diameters of permanent teeth of 36 plaster models (21 females and 15 males) of a group of Afro-descendants from the township of El Hormiguero, Cali, Colombia. Parametric and nonparametric tests were used to estimate sexual dimorphism and bilateral symmetry, in addition to correlations with Angle's molar class. A p < 0.05 was considered significant. Results: Minimal differences were found in the diameters of the right and left sides. Some lower ar...
