Prevalência e fatores associados ao uso de implantes dentários em idosos do sul do Brasil :um estudo transversal

Abstract

Objectives: To assess the prevalence and associated factors with use of dental implants among older adults. Methods: This cross-sectional study was performed with home-dwelling older adults from the cities Cruz Alta and Veranópolis, Brazil. The main outcome was obtained by a clinical oral examination, considering those with at least one dental implant. Independent variables were collected by a structured questionnaire. Crude and adjusted analysis were performed by Poisson regression with robust variance estimation. It was estimated the prevalence ratio (RP) and 95% confidence interval (95%CI) for the association between the outcome and independent variables. Results: It was included 569 participants, 287 (50.44%) and 282 (49.56%) from Cruz Alta and Veranópolis, respectively. The prevalence of using at least one dental implant was 16.7%. Higher PR for the use of dental implant was observed in white individuals (PR: 5.147; 95%CI: 2.033–3.034), in those with at least medium income (PR: 3.202; 95%CI: 1.196–5.572) and in those with access to dental care in the last 12 months (RP: 1.595; 95%CI: 1.087–2.340). Older adults with a medium level of education (RP: 0.484; 95%CI: 0.240–0.978) and those that did not use dental floss (RP: 0.627; 95%CI: 0.240–0.978) demonstrated a significantly lower PR for use of dental implants. Conclusion: A moderate prevalence of use of dental implants was observed among older adults. In addition, white ones, those with a better financial situation and users of dental floss presented higher use of dental implants.
