Resumen
La formación de dentina secundaria es un proceso que ocurre de manera gradual y constante una vez culminado el desarrollo del diente, ocasionando la disminución de la cavidad pulpar con el paso del tiempo. Su importancia para la práctica forense radica en la posibilidad de estimar la edad a partir del análisis de medidas lineales (principalmente) de la pulpa y raíz a partir de radiografías. El presente trabajo tiene como objetivo comparar y analizar el correlato entre la edad de los individuos y las medidas lineales y superficiales de diente y de pulpa. Fueron seleccionados 51 caninos superiores y 73 caninos inferiores pertenecientes a 84 individuos adultos provenientes de la colección Lambre (FCM-UNLP). Se relevaron y calcularon los cocientes correspondientes a partir del conjunto de medidas lineales y superficiales de pulpa y diente. Considerando el factor desgaste, se propuso calcular un nuevo cociente (APR) obtenido de medidas superficiales de cavidad pulpar y dentina<br />radicular (SP/SR). Los resultados obtenidos evidenciaron que las medidas superficiales se correlacionan mejor con la edad, y de éstas el APR fue el que mejor correlato etario manifestó.
Secondary dentine formation is a process that occurs gradually and steadily after the completion of tooth development, causing the pulp cavity to shrink over time. Its importance for forensic practice lies in the possibility of estimating age from the analysis of linear measurements (mainly) of the pulp and root from radiographs. The present work aims to compare and analyse the correlation between the age of individuals and the linear and superficial measurements of tooth and pulp. Fifty-one upper canines and 73 lower canines belonging to 84 adult individuals from the Lambre collection (FCM-UNLP) were selected. The corresponding ratios were collected and calculated from the set of linear and surface measurements of pulp and tooth. Considering the wear factor, it was proposed to calculate a new ratio (APR) obtained from surface measurements of the pulp cavity and root dentine (SP/SR). The results obtained showed that the surface measurements correlate best with age, and of these, the APR was the one that showed the best correlation with age.
