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

Objective 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. Methods 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. Results 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. Conclusions for Practice 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.
