Resumen

Este estudio evaluó la precisión del análisis fractal (FA) para estimar la edad cronológica y el sexo en individuos adultos brasileños para investigaciones forenses. La muestra balanceada estuvo compuesta por radiografías cefalométricas laterales de 120 individuos, las cuales fueron organizadas según grupo de edad (20-29, 30-39, 40-49, 50-59 años) y sexo (femenino y masculino). Todas las análisis de la rama mandibular y del ángulo mandibular fueron realizadas por un examinador capacitado y calibrado. Para la estimación de edad y sexo, se utilizó regresión lineal y análisis discriminante logístico múltiple. En consecuencia, verificamos la precisión del FA midiendo las diferencias entre la edad pronosticada y la real. Para todas las análisis, un valor de p <0,05 indicó la significancia estadística. En general, la media de los valores de la dimensión fractal (FD) fue 1,49 ± 0,10 para la rama mandibular y 1,48 ± 0,09 para el ángulo mandibular. En general, los hombres obtuvieron mejores resultados con el FA que las mujeres en la discriminación por edad y sexo. El análisis discriminante múltiple indicó que FA distingue el sexo en el 61,7% de los hombres y el 58,3% de las mujeres. Además, la diferencia media entre el valor real y el predicho fue de 9,5 años y 10,1 años para hombres y mujeres, respectivamente. Por lo tanto, observamos que FA es precisa para identificar cambios relacionados con el sexo y la edad en el patrón trabecular de la mandíbula de adultos brasileños en investigaciones forenses. Se necesitan más estudios que investiguen otras poblaciones para evaluar la precisión del FA para odontología forense.
