Australian aboriginal studies. 1. The effect of socio-economic changes on the prevalence of caries in 6-14 year-old children resident at Bathurst Island and Groote Eylandt in the Northern Territory of Australia, 1971.

Investigations carried out on 6--14 year-old Aboriginal children resident at Bathurst Island and Groote Eylandt showed that the Groote Eylandt children had a higher prevalence of dental caries at statistically significant levels. This difference in prevalence was attributed to the greater financial affluence at Groote Eylandt.
