In 60 (sixty) orthodontics models of plaster, it was measured the width mesio-distals of the teeth, from second molar to second molar, in both arches, using a modified sliding caliper. This project had as an objective to determine the average value for the width of each tooth and to observe the presence of sexual dimorphism, in white brazilians individuals, with an average age of 16.03 years old (25 male and 35 female), who were not treated orthodontically and that had normal occlusion, as it was described by Andrews. People's average values of the studied teeth were used to create a table, related to the superior and inferior arches. While analyzing the changes statistically changed, it was noticed a bigger mesio-distal width of the teeth from the male youngsters, related to the female ones.
