Income-related inequalities in unmet dental care needs in Spain: traces left by the Great Recession

Dental health is an important component of general health. Socioeconomic inequalities in unmet dental care needs have been identified in the literature, but some knowledge gaps persist. This paper tries to identify the determinants of income-related inequality in unmet need for dental care and the reasons for its recent evolution in Spain, and it inquires about the traces left by the Great Recession. Data from the EU-SILC forming a decade (2007-2017) were used. Income-related inequalities for three years were measured by calculating corrected concentration indices (CCI), which were further decomposed in order to compute the contribution of different factors to inequality. An Oaxaca-type decomposition approach was also used to analyze the origin of changes over time. Men and women were analyzed separately. Pro-rich inequality in unmet dental care needs significantly increased over time (CCI 2007: - 0.0272 and - 0.0334 for males and females, respectively; CCI 2017: - 0.0704 and - 0.0776; p
