Periodontal Infection and Inflammatory Markers in Missed Abortion
Official title: Salivary Periodontal Pathogen Burden and the Inflammatory-Prostaglandin E2 Axis in Missed Abortion Cases Without Fetal Chromosomal Abnormalities: A Case-Control Study
Run by Necmettin Erbakan University · NCT07864220 · Data updated 2026-11-12
Researchers will test whether gum infection and inflammation are linked to missed abortion in pregnant women with no major chromosomal problems.

Is this trial a fit for you?
✓Likely a good fit
Women aged 18-40 years, at 20 weeks of gestation or earlier, with a diagnosis of missed abortion or an ongoing uncomplicated pregnancy, matched by age and gestational age.
✕Probably not a fit
Individuals with fetal chromosomal abnormalities or the listed exclusion criteria may not see any direct benefit.

What this trial studies
This prospective, matched case-control study will compare 80 women with missed abortion to 80 women with ongoing uncomplicated pregnancies, all at 20 weeks of gestation or earlier. Each participant will undergo a periodontal exam and provide saliva for testing common periodontal bacteria and inflammatory biomarkers. Serum inflammatory markers will be measured from blood samples collected during routine obstetric care. Saliva samples are collected before periodontal probing to avoid contamination, and results will be analyzed to identify associations between oral health, bacterial burden, and systemic inflammatory markers with pregnancy outcome.
Why it matters
Potential benefit: If associations are found, it could inform future strategies to reduce pregnancy loss risk through management of periodontal health and inflammation.
How similar studies have gone: Prior studies have explored links between periodontal health and adverse pregnancy outcomes, but this specific matched case-control approach in missed abortion is relatively novel.
