Abstract

Objectives: The study aimed to examine individual and contextual factors associated with the frequency of dental service utilization among adolescents, adults and older adults Brazilians.

Methods: This cross-sectional study used secondary data from the Brazilian 2019 National Health Survey (94 114 individuals). The outcome 'when was your last dental appointment?' was categorized into three groups: up to 1 year, more than 1 year and never had a dental appointment. Andersen's behavioural model was used to select contextual and individual variables. Multinomial logistic regression analysis was performed to calculate the odds ratio (OR) and 95% confidence intervals (95% CI).

Results: The following variables showed increased probability to the outcome had the last dental appointment more than 1 year ago: older adult, illiterate or incomplete primary school, and without private dental insurance. The outcome never had a dental appointment was significantly associated with illiterate (OR 26.65; 95% CI 17.63-40.29), male (OR 2.38; 95% CI 2.17-2.61), without private dental insurance (OR 5.20; 95% CI 3.48-7.76), self-rated oral health as bad or very bad (OR 2.67; 95% CI 2.31-3.09), household not enrolled in primary care teams (OR 1.29; 95% CI 1.11-1.49), household in a rural area (OR 1.86; 95% CI 1.69-2.05), high household crowding (OR 1.08; 95% CI 1.04-1.14) and low household income per capita (OR 0.99; 95% CI 0.99-0.99).

Conclusions: This study showed that contextual and individual factors induce inequity in dental appointments. Moreover, Andersen's behavioural model demonstrated inequitable access for dental services in Brazil, in which social structure and enabling characteristics, rather than the need for the service, determine who receives health care. Living in a household enrolled in primary care teams favoured regular dental appointments. Thus, these findings may help policymakers improve health access by expanding coverage of dental services in primary health care.
