Impact of COVID-19 on Dental Care Utilization and Oral Health Conditions in the United States.

Purpose: We aim to understand the impact of the COVID-19 on health care utilization and oral health conditions of patients at federally qualified health centers (FQHCs), where patients are disproportionately low income, publicly insured, or uninsured.

Methods: Using deidentified electronic health records of patients at FQHCs in the United States from January 2019 through December 2020 (n = 431,509), variations in health care utilization since the COVID-19 outbreak were observed by procedure types and patient characteristics. Changes in dental utilization and oral health conditions were characterized using mixed-effect negative binomial and logistic regression models.

Results: Dental utilization decreased more drastically than medical utilization during shelter-in-place periods in 2020 and rebounded more slowly after the reopening. Greater demands for oral surgery and teledentistry and less demands for preventive services were observed in 2020. As compared to 2019, patients experienced more psychological stress-related dental conditions with odds ratios of 1.52 (95% confidence interval [CI], 1.31-1.76) for uninsured, 1.48 (95% CI, 1.07-2.02) for Medicaid enrollees, and 2.38 (95% CI, 1.68-3.40) for private insurance beneficiaries.

Conclusion: As a result of COVID-19, patients received more invasive dental procedures due to delayed treatment and experienced a higher risk of psychological stress-related dental conditions. Continued support for statewide policies to expand access to oral health care and oral health promotion strategies for the vulnerable populations would be encouraged.

Knowledge transfer statement: Our study describes the impact of COVID-19 on dental care use and oral health conditions at Federally Qualified Health Centers, targeted to provide care for some of the most vulnerable populations in the United States. The results of this retrospective cohort study can be used by clinicians and policymakers on understanding the clinical needs of the vulnerable populations after the pandemic. It highlights the need for continued support to expand access to oral health care and oral health promotion to these populations.
