A recent (Fall 2007) research article in the Journal of Public Health Dentistry which analyzed data collected between 1996 and 2004 found that there were significant racial and disparities among children receiving orthodontic care. Black and Hispanic children had lower odds of receiving care than White children, and the rates of care were also affected by income and access to private health insurance.
