Use of dental implants among older adults of two southern Brazilian cities: A population-based cross-sectional study

Aim: 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 Veranopolis, 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 was performed by Poisson regression with robust variance estimation; results are presented in prevalence ratio (PR) and 95% confidence interval. Results: It was included 569 participants. The overall prevalence of using at least one dental implant was 16.7%. Higher PR for the use of dental implants 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 substantial 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.
