Objectives This questionnaire-based cross-sectional study aimed in the evaluation of oral hygiene and oral health behavior, periodontal complaints and oral health-related quality of life (OHRQoL) in pregnant women in southwest-Saxony, Germany. Materials and methods Consecutive patients attending the clinics for Obstetrics and Gynecology, Heinrich-Braun-Klinikum Zwickau, Germany, were recruited in the years 2020 and 2021. The evaluation consisted of three parts: (I) dental and oral hygiene behavior, (II) periodontal complaints and (III) German short form of oral health impact profile (OHIP G14) to assess OHRQoL. Results 853 out of 1056 participants were included in the study. The pregnant women reported that they have received information on oral health during pregnancy more often from gynecologists than from dentists. Slightly more than half of the participants (51.5%) rated to regularly undergo a professional tooth cleaning. Similarly, nearly half of the women stated to perform interdental cleaning (55.8%). The most common periodontal complaint was bleeding of the gums (45.4%). The OHIP G14 findings of all questions as well as sum scores showed a median of 0. Regression analysis revealed that regular professional tooth cleaning was a predictor of better OHRQoL (β – 0.698, CI95 0.049–1.299; p < 0.04). Conclusion Oral hygiene and oral health behavior of pregnant women in southwest-Saxony requires improvement. While the overall OHRQoL of the cohort was not reduced, professional tooth cleaning and thus professional preventive measures can support OHRQoL during pregnancy. Improved interdisciplinary oral health care concepts for pregnant women should be fostered. These concepts can also positively influence OHRQoL issues.
