RESUMEN: Se estudió la prevalencia de 25 rasgos dentales en un grupo de cráneos adultos prehispánicos, conservados en el Museo de La Plata (Argentina). Fueron analizadas ambas arcadas y la totalidad de las piezas dentales de la dentición permanente excepto los terceros molares. El principal objetivo de este estudio es establecer el patrón morfológico dental, según las frecuencias absolutas y relativas de los rasgos que caracterizan a la dentición de la serie Araucanos. Se puede concluir, por las frecuencias presentadas en los rasgos analizados, que la muestra presenta similitudes con las poblaciones mongoloides sinodontes y se aleja de las poblaciones europeas y africanas.
SUMMARY:The present study was carried out with a Calchaquí 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 >70% was found only in 4 traits. Calchaquí 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.
Dental morphological trait expressionshave been used in anthropology and forensic sciences fordetermination of biological and geographical affiliations.The present study was carried out with a Chubut preconquestsample from Patagonia, Argentina. 18 skullswith partial dentitions from Chubut (Patagonia) wereanalyzed. The ASU Dental Anthropology System wasused to register the expression grade of all dental traits.In spite of small sample sizes, we can conclude thatshovel shape (UI1, UI2), two lingual premolar cusps(UP1, UP2), and hypocone (UM1, UM2) frequenciessuggest a Mongoloid (Sinodont) origin.
analizando las arcadas superiores e inferiores de los mismos y la totalidad de las piezas dentales, excepto los terceros molares. El estudio se realizó sobre la dentición permanente de 66 cráneos adultos -maduros. Se establecieron las frecuencias absolutas y relativas de los rasgos estudiados.
