title: Bilateral asymmetry in permanent dentition of 13 pre-conquest samples from Argentina (South America).
abstract: Bilateral asymmetry is an important field of study in anthropology. The evaluation of bilateral asymmetry of 44 dental non-metric traits of permanent dentition is carried out in this study on 376 adult skulls from different archaeological sites in Argentina (South America). From a total of 44 traits studied, just 12 (27% of the total traits expressed) presented Bilateral Index (BI) values lower than 100% (between 92% and 99%). Results suggest that the expression of all dental traits is probably bilateral. These results show the importance of analysis of bilateral asymmetry for assignment of taxonomic and population value of non-metric dental traits.
