Research team of dental anthropology of the department of Basic Sciences, Faculty of Dental Sciences is conducting a research project on metric and non-metric dental characteristics of aboriginal Vedda people in Sri Lanka. There are three Vedda communities in the country namely, Uva-Bintenna Vedda in Uva province (Southeast part of the country), Anuradhapura Vedda in North Central province and Coastal Vedda in Eastern province. This is the first ever comprehensive dental anthropological survey conducted in Sri Lanka which covers all three Vedda populations. The research team had already collected over 250 dental plaster casts visiting 5 Vedda villages in Anuradhapura district. Recently, they visited two villages (Kirimichchai and Kunchankulam) in Wakarai in Batticaloa district and collected dental plaster casts from Coastal Vedda people whose origin and affinities are hardly known. This project leads to an Mphil degree of a postgraduate student in the Basic Sciences Department. Researchers expect that, findings of this project will provide very important and significant information of the origin and migration of Vedda populations in Sri Lanka.
