Oral health self-perception in quilombola communities in Rio Grande do Sul: a cross-sectional exploratory study.

Objective: There's a shortage of evidence on the oral health of quilombolas. This study aims to describe oral health self-perception, as well as to verify its associated factors in quilombola communities in the state of Rio Grande do Sul. Methods: The data for this cross-sectional health survey were collected by application of a questionnaire. Since this study was part of a survey on nutritional security, the probabilistic cluster sample was estimated for the outcome of nutritional insecurity, comprising 583 individuals across quilombola communities in Rio Grande do Sul. The association between the outcome of negative oral health self-perception and sociodemographic, general health, and oral health variables was measured by prevalence ratios obtained through Poisson regressions with robust variance and 95% confidence intervals. Results: Negative self-rated oral health was reported by 313 (53.1%) of the individuals. Satisfaction with chewing ability and satisfaction with oral appearance were associated with a higher prevalence of negative perception of oral health, while there was no association between the outcome and number of teeth. Use of alcohol had a borderline association with the outcome. Conclusion: Satisfaction with appearance and chewing ability are factors associated with oral-health self-perception of the quilombolas in Rio Grande do Sul.
