(719) Antenatal Characteristics Predict Need for Dental Referral Using the ACOG-Recommended Oral Health Screening Tool

10:30 AM – 12:30 PM  
Objective: The American College of Obstetricians and Gynecologists (ACOG) recommends screening pregnant patients with a 3-question survey at their first prenatal visit for oral health. We sought to evaluate which characteristics are associated with an overall positive screen (defined as a positive response on any of the three questions) or with positive screen for each specific question.

Study Design: We screened pregnant individuals at a university-based prenatal clinic using the 3-question ACOG screening tool (Figure 1). We p</span>erformed generalized linear models with stepwise forward AIC regression to evaluate antenatal characteristics (Table 1) with a positive overall screen and each specific question including adjusted odds ratios per included variable. Missing data for binary risk factors was imputed assuming the predictor was unknown. The dataset was divided 80:20 for model development and validation, respectively. 

Results: Among 817 patients that completed the ACOG screen, 44.9% screened positive (367/817) with 14.9% (122/817) screening positive on question 1, 37.1% (303/817) on question 2, and 5.8% (48/817) on question 3. The models predicted 89.5%, 78.0%, and 93.2% accuracy with a positive screen for questions 1, 2, or 3, respectively. The model also predicted a positive overall screen with 66.7% accuracy. Antenatal factors with >1.5-fold increased odds of a positive overall screen (Figure 1A) and symptomatic oral disease (Figure 1B) were Medicaid insurance, self-identifying as Hispanic, having COVID, or having substance abuse during pregnancy.

Conclusion: Our models using antenatal characteristics can accurately (≥89%) predict symptomatic oral disease in pregnancy. Medicaid insurance, self-identifying as Hispanic, having COVID or substance abuse during pregnancy were strongly associated with increased odds of having symptomatic oral disease or needing referral to a dentist underscoring that health disparities are present related to oral care in pregnancy. Antenatal efforts improving access to oral health in pregnancy are needed to reduce health disparities.
