Summary
Summary: Health Resources and Services Administration-funded health centres (HCs) are an important source of dental services for low-income and vulnerable patients in the United States. About 82% of HCs in 2018 had dental workforce, but it is unclear whether this workforce meets the oral health needs of HC patients. Authors first examined (a) whether dental workforce was associated with any dental visits vs. none and (b) whether HC patients with any visits were more likely to have a visit at the HC vs. elsewhere. Authors then examined (c) if need for oral health care and long-term continuity at the HC were associated with dental visits and visits at the HC.
This study used the 2014 Health Center Patient Survey, a nationally representative study of U.S. HC patients, and the 2013 Uniform Data System, an administrative dataset of HC characteristics, and the 2013 Area Health Resource File to measure the contribution of local supply of dentists.
Findings: Larger dental workforce at the HC was significantly associated with 1% higher likelihood of any visits and 10% higher likelihood of a visit at the HC among those with a visit. Patient self-reported oral health need was positively associated with 157% higher likelihood of dental visits, and 42% higher likelihood of dental visit at the HC vs. elsewhere. Long-term continuity with the HC was not significantly associated with likelihood of dental visits, but was associated with 26% higher likelihood of visits at the HC among those who had any visits.
The findings highlight the potential impact of increasing dental workforce at HCs to promote access; the high level of need for oral health care at HCs; and the increased effort required to promote access among newer patients who may be less familiar with the availability of oral health care at HCs. Together, these findings reinforce the importance of addressing barriers of use of oral health services among low-income and uninsured patients.
