(Universidad Privada Norbert Wiener, 2019-11-16) Quiroz Coronado, Miguel Angel; Fox Cortez, Julio Alonso
The main objective of this research is to determine to what extent the predictive power of height estimation is influenced by the Carrea Method in the real stature of the students of the Subject of Forensic Stomatology of the University of San Martín de Porres in the District of San Luis. Odontometry, branch of Dentistry, is the procedure for obtaining measurements of the mesiodistal diameters of the teeth; that applied to a formula originally made by Dr. Juan Ubaldo Carrea, where the length of the chord radius and the mandibular dental arc are determined from the central incisor, lateral incisor and canine lower unilateral parts and then by mathematical techniques to establish a formula that allows to predict the stature of the individual. In the present work, 64 students of the subject of Forensic Stomatology of the Faculty of Dentistry of the University of San Martín de Porres, Lima-Peru, semester 2018-II, where the records of the dental arches for using dentistry to determine the mesiodistal diameters of the front lower dental pieces that will serve as an input to estimate by the mathematical formulas developed by Dr. Ubaldo Carrea the stature with the lowest level of error possible. A non-experimental, cross-sectional and correlational study of predictive type was performed, where the height and dental dimensions of 64 students of both sexes with ages between 20 and 37 years were analyzed to test the hypothesis of the existence of direct and statistically significant correlation between height real and minimum and maximum height obtained by the Carrea method and the existence of differences in the prediction of height according to sex and age groups. Only 17,2% of the correct height was found, there being a significant difference between the sexes, being the male students those who obtained the highest percentage of success (44,4%). No statistically significant correlation was found between the actual height and the minimum and maximum heights. A multiple regression formula was obtained that involves, as explanatory variables of the stature, the stature calculated by the Carrea method and the radio cord dimension. In this obtained formula, 59,4% of the total variation is explained by the relationship between the dependent variable (real stature) and the independent variables (calculated height and radius chord). In conclusion, it is described that the Carrea method cannot be used to estimate the height of the studied population, since no correlation was found between dental dimensions, method calculations and real height. Due to the low predictive power obtained other more accurate and valid complementary alternatives should be used to estimate height accurately.
