Abstract It is important to have an epidemiological understanding of oral diseases among indigenous persons, in order to contribute with the organization of health services for these populations. The SB Brasil 2010 database was used to compare the prevalence of dental caries among 308 self-identified indigenous and 37,211 non-indigenous individuals from urban areas, in the following age/age-groups: 5, 12, 15-19, 35-44, 65-74. The study also analyzed the effect of the complex sample design and the sample weight in the outcomes. Kruskal-Wallis, Wilcoxon Scores (Rank Sums), logistic and multiple linear regressions were used for statistical analysis. The mean dmft index for indigenous and non-indigenous children aged five were 4.02 ± 4.01 and 2.41 ± 3.35, respectively, and 46% of non-native and 30.8% of native children were caries-free. The mean DMFT for indigenous and non-indigenous were 10.90 ± 11.69 and 10.93 ± 11.58, respectively, for all age groups when not taking into account the sample weight effect. When considering the complex sample design and the sample weight effect, the study found a statistical significant difference. The results lend credence to suspicions that in Brazil there are disparities in the patterns of caries between self-identified indigenous and non-indigenous individuals.
