Abstract
Objective

Evaluate the usefulness of the dental method of Carrea to estimate the height in Mexican population.

Materials and methods

Analytical, correlational and cross-sectional study in 2 cadaveric Mexican populations. Sample: 56 bodies, 32 of Veracruz and 24 of the Federal District. In each corpse 4 morphometric measurements were performed, of which 5 derivatives were obtained. Statistical analysis: (1) mean and standard deviation (SD) was calculated; (2) for sex, t-Student and Levene tests for comparison of means and SDs were used; (3) to calculate the variability between Federal District and Veracruz, principal component analysis was made; (4) the heights, real, minimum, average and maximum were compared by univariate ANOVA, and (5) a Pearson correlation analysis between actual and minimum heights was performed.

Results

No differences were found between the 2 cadavers samples studied, neither between real and minimum height in either group: Federal District, real height (172.08±6.53cm) and minimum height (171.35±7.81cm) (P>.05); Veracruz, real height (167.5±5.77cm) and minimum height (166.50±6.36cm) (P>.05), having that the correlation between real height and the minimum height is advisable for both samples, Federal District (r=.79, P=.000), Veracruz (r=.82, P=.000) and overall (r=.83, P=.000).

Conclusions

The dental Carrea's method, using the minimum height reference, is an excellent estimate of the actual size in Mexican corpses.

Resumen
Objetivo

Determinar la efectividad del método odontológico de Carrea para estimar la talla real de cadáveres mexicanos.

Material y métodos

Estudio analítico, correlacional y transversal en 2 poblaciones mexicanas cadavéricas. Muestra: 56 cadáveres, 32 de Veracruz y 24 del Distrito Federal. En cada cadáver se realizaron 4 mediciones morfométricas, de las cuales se obtuvieron 5 derivadas. Análisis estadístico: 1) se calcularon media y desviación estándar (DE); 2) para sexo, se utilizaron las pruebas t Student y de Levene para comparación de medias y DE; 3) para calcular la variabilidad entre muestras, se realizó un análisis de componentes principales; 4) las tallas real, mínima, máxima y promedio se compararon mediante un ANOVA unifactorial y 5) se realizó un análisis de correlación de Pearson entre las tallas real y mínima.

Resultados

No se encontraron diferencias entre las 2 muestras de cadáveres estudiadas ni entre las tallas real y mínima en ninguno de los 2 grupos: Distrito Federal, talla real (172,08±6,53cm) y talla mínima (171,35±7,81cm) (p > 0,05); Veracruz, talla real (167,5±5,77cm) y talla mínima (166,50±6,36cm) (p > 0,05). Se obtuvo que la correlación entre la talla real y la mínima es adecuada tanto para la muestra del Distrito Federal (r=0,79; p=0,000) como para la de Veracruz (r=0,82; p=0,000), así como en conjunto (r=0,83; p=0,000).

Conclusiones

El método odontológico de Carrea, utilizando la talla mínima como referencia, es un excelente estimador de la talla real en cadáveres mexicanos.
