This study aims to evaluate the prevalence of tooth decay in the riverine population of Mamirauá Sustainable Development Reserve - MSDR, Amazonas, Brazil, as well as, to contribute to a better planning and implementation of public policies for oral health in those communities. The 2001 study examined 8 MSDR’s communities with a population sample of 486 residents, between 1 and 70 years of age, divided into four age groups. For measuring the experience of tooth decay in permanent and deciduous teeth DMFT (decayed, lost and filled teeth) and deft indexes (decayed, extraction indicated and filled teeth) were used respectively. As a result, a 7.54 average DMFT and a 3.48 deft were observed. The age group with the fewest people free from tooth decay was that above 19 years, only 1.4% was free. And the largest component to the DMFT index contribution was loss by caries (68.90%), while decayed teeth for the deft index (90.54%). This data is disturbing concerning tooth decay in the communities of MSDR. The study stresses a need for a more effective public policies involving dental health for that population.
