摘要
The present study was carried out with a Calchaqu赤 human Pre-Conquest sample from Northwest of Argentina, with the aim of exploring the dental morphology patterns in this population. This study was carried out by means of a macroscopic analysis in permanent dentitions of 7 skulls. 40 dental non-mtetric traits were recorded using the ASU Dental Anthropology System. Percentages %26gt;70% was found only in 4 traits. Calchaqu赤 sample studied here is near to these values in shovel shape expression, but the results of this study suggest that a Sinodont pattern is no clear for this sample. To conclude, the present investigation provides additional, insightful elements for a description of biological factors in the process of dental morphologic diversification associated to regional and temporal ranges in this region of Argentina. Estudiamos una muestra Pre-Conquista de Calchaqu赤es del Noroeste de Argentina, con el objetivo de explorar patrones de morfolog赤a dental presentes en esta poblaci車n. Se realiz車 un an芍lisis macrosc車pico en dentici車n permanente de 7 cr芍neos. 40 rasgos no-dentales fueron registrados utilizando el ASU Dental Antropology System. Porcentajes mayores al 70% fueron encontrados solamente en 4 rasgos. La muestra estudiada est芍 cerca de valores en la expresi車n de la forma de pala, pero los resultados de este estudio sugieren que un patr車n Sinodonte no es claro para esta muestra. Para concluir, la presente investigaci車n brinda adicionalmente, profundos elementos para una descripci車n de los factores biol車gicos en el proceso de diversificaci車n morfol車gica dental asociada a los rangos regionales y temporales en esta regi車n de Argentina.
