ABSTRACT
The goal of the Patient Protection and Affordable Care Act (ACA) is to increase access to health insurance and decrease health care cost while improving health care quality. With more articles examining the relationship between one of the ACA provisions and dental health outcomes, we systematically reviewed the effect of the ACA on dental care coverage and access to dental services. We searched literature using the National Library of Medicine's Medline (PubMed) and Thomson Reuters' Web of Science between January 2010 and November 2020. We identified 33 articles related to dental coverage, and access/utilization of dental care services. This systematic review of studies showed that the ACA resulted in gains in dental coverage for adults and children, whereas results were mixed with dental care access. Overall, we found that the policy led to a decrease in cost barriers, an increase in private dental coverage for young adults, and increased dental care use among low-income childless adults. The implementation of the ACA was not directly associated with dental insurance coverage among people in the U.S. However, results suggest positive spillover effects of the ACA on dental care coverage and utilization by people in the national level dataset.
