Resumen
Este trabajo busca ampliar el conocimiento que se posee sobre variables dentales no métricas en aborígenes argentinos y fortalecer las bases de la antropología dental en nuestro país. Se ha estudiado la prevalencia del rasgo denominado hipocono en una muestra de cráneos adultos, abarcativa de la mayor parte de la superficie del territorio. A partir de los valores obtenidos para este rasgo en los cráneos analizados, se compararon las frecuencias relativas porcentuales entre la serie analizada y varias poblaciones mundiales estudiadas por otros autores. Se ha contrastado la hipótesis de afinidad entre poblaciones a través del cálculo de z de frecuencias relativas. Para este rasgo las mayores afinidades se han encontrado con la población japonesa amami, con grupos ainu, con muestras polinesias y hawaianas y con las poblaciones americanas iroquesas y peruanas. Las mayores diferencias se hallaron con los grupos africanos subsaharianos y del norte de África, como así también con la población aleutiana.
This paper intends to widen the knowledge we have about non-metric dental traits in Argentine aborigines, strengthening the bases of dental anthropology in Argentina. The prevalence of the trait known as hypocone was studied in a cluster of Argentine aboriginal adult skulls, composed by skulls series from most of the Argentine territory. The relative frequencies for this trait were determined for the cluster, and they were compared with the frequencies of the same trait in populations from all over the world published by other authors. The affinity hypothesis among populations has been verified by determining the z for relative frequencies. The closest affinities between the Argentine sample and the rest of the populations were found in the Japanese Amami population, the Ainu groups, the Hawaiian and Polynesian samples, and the Iroquois and Peruvian populations. The greatest differences were shown in the African sub-Saharan groups, the North African groups, and the Aleutian population.
