Which adverse pregnancy outcomes are linked to poor oral health during pregnancy?

• A. Gestational diabetes
• B. Preeclampsia
• C. Preterm birth & low birth weight infants
• D. Gestational diabetes, preeclampsia, and preterm birth with low birth weight

Answer: (D)

Poor oral health during pregnancy can trigger a systemic inflammatory response that affects the pregnancy environment. Periodontal disease allows bacteria and inflammatory mediators to enter the bloodstream, reaching the placenta and influencing its function. This inflammatory cascade is linked to several adverse outcomes.

The pathways involved can contribute to preterm birth and restricted fetal growth, due to inflammatory signals that can stimulate early labor and impair fetal development. They’re also associated with preeclampsia, a condition marked by placental dysfunction and systemic inflammation, which can be influenced by the same inflammatory milieu. Additionally, inflammation linked to periodontal disease may influence glucose metabolism and insulin resistance, contributing to gestational diabetes in some cases.

Because all three outcomes have been observed in association with poor oral health, the most comprehensive answer includes gestational diabetes, preeclampsia, and preterm birth with low birth weight. Keep in mind these are associations, not guaranteed causes, and maintaining good oral hygiene and dental care during pregnancy is a prudent part of prenatal health.
