The use of dental services in the past year in the brazilian populatioa systematic review with meta-analysis

Abstract

The scope of this study was to ana-lyze the factors associated with the use of dental services in Brazil. The review strategy included PubMed, SciELO, LILACS, BBO, EMBASE, Scopus, WOS and Google Scholar databases, in addition to repositories and databases of disser-tations and theses. Studies were selected using the PEO (Population/Exposure/Outcomes) strategy. The outcome of this study was the use of dental services in the last year by the Brazilian popu-lation, treated as dichotomous variables for the following analyses: ≤ 1 year and > 1 year. Man-tel-Haenszel random effect meta-analysis was performed, estimating Prevalence Ratios (PR) and 95% confidence intervals (95%CI). A total of 94 studies were selected. The majority (98%) had a cross-sectional design, with 63% derived from primary data. For the meta-analysis, 25 studies were included. The use of oral health services in the last year was associated with higher educa-tion (≥ 8 years of schooling) (PR = 0.49, (95%CI: 0.39-0.60)); higher family income (≥ 2 minimum wages) (RP = 0.79, (95%CI: 0.74-0.84)); and living in urban areas (RP = 0.79, (95%CI: 0.64-0.97)). The availability of dental services in the Unified Health System needs to be made readily accessible to people with lower income, less edu-cation and those living in rural areas.
