Resumen

Objective: To determine the mesiodistal, palatal vestibule and lingual vestibule diameters of the first permanent molars of both jaws for the estimation of sex, in Dentistry students of the Federico Villarreal National University, Lima-Peru. Material and methods: The type of research used was descriptive with a non-experimental design, the applied technique was direct observation, the population consisted of 605 students. Impressions of both jaws were made with condensation silicone to obtain the study models, a digital vernier caliper was used to make the mesiodistal and palatal vestibule and lingual vestibule measurements, the measurements were made on a sample of 207 models of both sexes. Results: The odontometric characteristic with respect to the vestibule-palatal/lingual diameter of both jaws, for the male sex had a diameter of 11.2mm (pza.16), 11.3mm (pza.26), 11.01mm (pza.36) and 11.02mm (pza.46) and values of 10.88mm (pza.16), 10.93mm (pza.26), 10.77mm (pza.36), and 10.74mm (pza.46), in the female sex; Regarding the mesio-distal odontometric characteristic, a diameter of 10.8mm (pza.16), 10.76mm (pza.26), 11.44mm (pza.36) and 11.45mm (pza.46) was found for the male sex. and values of 10.56mm (pza.16), 10.58mm (pza.26), 11.10mm (pza.36), and 11.2mm (pza.46), in the female sex. Conclusion: The mesiodistal and palatal vestibule diameters were greater in males.
