Place of Birth Inequalities in Dental Care Use before and after the Economic Crisis in Spain.

This study evaluates inequalities in the use of dental services according to place of birth before and after the economic crisis in Spain. A cross-sectional study was performed in adults aged 18 to 65 years in Spain. We used data from three Spanish National Health Surveys for the years 2006 (before the crisis), 2014, and 2017 (after the crisis). Log-binomial regression was used to quantify the association between place of birth and use of dental care services before and after controlling for the selected covariates. In 2006, we found a greater probability of not using dental care services in immigrants from Asia (PR: 1.36, 95% CI: 1.10-1.67) and Africa (PR: 1.16, 95% CI: 1.05-1.28) compared to the natives. For 2014, the probability of not using dental care services was greater for all immigrants relative to natives, with the greatest probability for those from Africa (PR: 1.71, 95% CI: 1.46-2.01) and Asia (PR: 1.3, 95% CI: 1.23-1.47). The associations for 2017 were weaker in magnitude than the ones observed for 2014, although stronger than for 2006. This study suggests that the economic recovery did not have the same impact for natives and immigrants regardless of regions of origin, given the observed inequalities in use of dental services.
