Use of dental services by disability status in Brazil in 2013.

Abstract

OBJECTIVE\nTo describe the prevalence and factors associated with the use of oral health services in people with and without disabilities in Brazil.\n\n\nMETHODS\nA cross-sectional study was used with the secondary data of 60,202 individuals from the Brazilian National Health Survey of 2013. The main exposure variable was Disability , and the main outcome was Dental service use . Independent variables were selected using the modified Andersen and Davidson model, according to four groups: exogenous variables, primary determinants of oral health, health behaviours and oral health conditions. The analysis was based on a hierarchical approach stratified by disability (yes/no) , with multiple logistic regression incorporating sampling design. Interaction terms between the disability variable and covariates were tested in logistic regression models.\n\n\nRESULTS\nA total of 45.5% of the people without disabilities and 34.1% of those with disabilities visited the dentist in the last year. In the crude model, the nondisabled group used dental services more (OR\xa0=\xa01.61, 95%CI\xa0=\xa01.45-1.79), but the difference was no longer significant (OR\xa0=\xa01.18, 95%CI\xa0=\xa00.93-1.51) when adjusted by the health behaviour and oral health condition blocks. Determinants of dental use were similar among people with and without a disability.\n\n\nCONCLUSIONS\nNo difference in dental service use according to disability status was found after adjusting for oral health conditions. Although edentulism is more prevalent among disabled people, they do not go to the dentist as regularly as nondisabled people. Health services should actively schedule maintenance visits to ensure that the needs of disabled individuals are fully addressed.
