Factors contributing to socioeconomic gradients in children's oral health between 1993 and 2003

The NHMRC and the Australian National Oral Health Plan have identified health inequalities as a critical health issue. Dental caries in children increasingly has become concentrated in disadvantaged population groups. While previous studies have documented socioeconomic gradients in oral health, few have sought to explain the reasons underlying those inequalities. By taking advantage of two existing datasets of child oral health in Australia, collected in 1992 and 2002, we will be able to quantify change in socioeconomic inequalities in oral health, and identify population-wide exposures to preventive practices and social circumstances that may have contributed to that change.
