Changes in Inequalities of Access to Dental Care in Australia 1977-2005

Information on dental visits, income and demographic variables were drawn from the Australian National Health Survey between 1977 and 2005. Income‐related inequality in access to dental care was calculated using the generalised concentration index (G) and decomposition methods were employed to examine associations with socio‐demographic and policy‐amenable factors. Statistically significant increases in inequality in dental care use were found after 1995. From 0.026 in 1995, G increased to 0.045 in 2005. The associations between increases in inequality and changes in the uptake of private health insurance suggest a contributory role of the introduction of the Commonwealth government's 30 per cent rebate for private health insurance.
