Measurements of Mayoral index and transversal diameter of jaws, comparison in students of Basic Secondary

A cross-sectional descriptive study was carried out in the period November 2013 to 2016, to compare the measurements of Mayoral with the transversal diameter of the jaws in the students of 12-14 years of the ESBU "Pedro Pablo Pérez" Guantanamo. The universe was made up of 60 students from 12 to 14 years of the educational entity. The variables were studied: age, sex, transversal measurements of the jaws, transversal measures of Mayoral and their diagnostic significance. Measurements of the transverse distances between the first and second premolars and first permanent maxillary molars were made and the parameters obtained with the references established by mayoral were compared. The investigation revealed a greater number of female than male patients, variations between sexes were found in dental exams, predominating big diameters in male sex. There was a statistically significant difference between the transversal measures of the studied population and the measures established by mayoral.
