Description
Summary:In recent human populations there is a pattern of geographic variation associated to the tooth morphology. In the last decades there has been a remarkable scientific production around the study of non-metric dental traits in order to define the geographic patterns of groups, their history, origin or structure, among others. Between the proposed scopes is the possibility of using the frequency of different traits of expression in a forensic context. We present a review of the literature in MEDLINE, SciELO, and LILACS and REDALYC databases. Full articles in Spanish, Portuguese and English conducting analyzes of dental morphological traits in present South American populations (XX and XXI centuries) were included. Two researchers evaluated the selected articles independently. The search strategies allowed identified 36 studies with a significant participation of Colombia (both authors and samples), followed by Chile and Brazil. While these results demonstrate a robust activity in the field of dental anthropology studying South- American present populations, a reevaluation of the methodologies is suggested if it is to assign a forensic value to dental morphological traits. KEY WORDS: Dental anthropology; Non-metric traits; South-America; Forensic dentistry. En las poblaciones humanas recientes existe una patron de variacion geografico asociado a la morfologia del diente. En las ultimas decadas se ha generado una notable produccion cientifica en torno al estudio de los rasgos dentales no metricos con el fin de definir los patrones geograficos de los grupos, su historia, origen o estructura, entre otros. Entre las aplicaciones propuestas esta la posibilidad del uso de la frecuencia de los diferentes rasgos de expresion en un contexto forense. Se presenta una revision de la literatura en las bases MEDLINE, SciELO, REDALYC y LILACS. Se incluyeron articulos completos, en espanol, portugues e ingles, que realicen analisis de rasgos morfologicos dentales en poblaciones sudamericanas actuales (siglos XX y XXI). Los articulos seleccionados fueron evaluados por dos investigadores de manera independiente. Las estrategias de busqueda permitieron pesquisar 36 estudios con una importante participacion de Colombia (tanto en autores como en muestreos), seguida por Chile y Brasil. Si bien estos resultados demuestran una robusta actividad en el ambito de la antropologia dentaria Sudamericana estudiando poblaciones actuales, se sugiere una reevaluacion de las metodologias emplea
