The Coronal Pulp Cavity Index: A Forensic Tool for Age Determination in Human Adults

La correlacion entre la reduccion de la cavidad coronal pulpar y la edad cronologica ha sido estudiada en una muestra de 846 dientes intactos procedentes de 433 individuos de sexo y edad conocidos. La radiografia panoramica ha sido utilizada para medir el largo (mm) de la corona (CL=coronal length) y el largo (mm) de la cavidad coronal pulpar. El indice dentario "Tooth coronal index" (TCI) segun Ikeda et al. (1985) ha sido calculado por cada diente para determinar la edad real del individuo con el metodo de la regresion. Los coeficientes de regresion varian de -0.92 (molares, muestra total, lado derecho) a -0.87 (molares femeninos) con un S. E. de estimacion de 5.88 a 6.66 anos. Las correlaciones son mas altas en los varones respecto a las mujeres. Las ecuaciones obtenidas lograron estimar la edad en una muestra de 100 dientes (no utilizados en la regresion) con un error de ± 5 anos en el 81.4% de los casos por los molares masculinos. El estudio ilustra el valor potencial de un metodo que puede ser utilizado para estimar la edad en individuos vivos y material esqueletico de edad desconocida.
