Retrospective Study of Prenatal and Postnatal Gaps in Oral Health Care Utilization: Medicaid Policy Implications

To assess the frequency and timing of dental treatment completion among pregnant and post-partum women served through the University of North Carolina at Chapel Hill (UNC-CH) Prenatal Oral Health Program (pOHP) dental clinic in the context of North Carolina (NC) dental Medicaid policies.

We completed a retrospective chart review of pregnant women referred to the program between May 2015 and May 2019. Data were collected from the time of referral until up to 2 years after their estimated due date (EDD). We assessed pre- and post-delivery dental appointment timing and dental treatment completion.

The initial study population included 264 pregnant women. Overall, 213 patients (81%) attended at least one appointment, and 32 patients (12%) completed recommended treatments prior to their EDD. Fifty patients (19%) returned after delivery to resume dental care, with only 25 patients (10%) completing their recommended treatment plan. Women re-entered dental care at a median of 67 days (range 5-613 days) after their EDD and completed treatment at a median of 378 days (range 52-730 days) following delivery.

Despite dental clinic referral, most pregnant women do not complete recommended dental treatment before giving birth, and women who resumed dental care after birth demonstrated a lag-time between delivery and care completion. These findings highlight the need for extending post-pregnancy dental care coverage, which is limited under current dental Medicaid policies, posing a major public health issue for new mothers to continue oral health care.
