The aim of this study was to analyze the association between maternal oral knowledge and the level of oral health during pregnancy with the risk of obstetric complications and breastfeeding. A descriptive cross-sectional study was conducted after an oral health educational intervention in a consecutive sample of 97 pregnant women. Data collection consisted of a validated questionnaire, oral examination, the Caries Index (CAOD) and the Simplified Oral Hygiene Index (IHOS). The participants had a mean age of 32.5 \u00b1 5.19 years and a predominantly university education (57.1%). The level of knowledge regarding oral health was fair (12.5 \u00b1 3.56 correct answers). Older pregnant women (33.0 \u00b1 4.80 years) practiced breastfeeding and had a higher number of correct answers to the questionnaire. Adequate IHOS was associated with higher birth-weight newborns (3333 \u00b1 0.3), whereas poor oral hygiene control was associated with lower birth-weight newborns (2960 \u00b1 0.1) (p &lt; 0.05). A lower level of academic education was associated with worse oral hygiene (p &lt; 0.05). In addition, the greater the number of children, the higher the CAOD. Finally, among non-smoking women, the weight of infants was 437 mg higher. Maternal oral hygiene and the week of delivery were associated with newborn weight (p &lt; 0.05) in a multiple linear regression model. Smoking was also related to low birth weight (p &lt; 0.05). Educational interventions in pregnancy are necessary to decrease the incidence of obstetric adverse effects and improve the oral health of mothers and their children.<\/jats:p>","DOI":"10.3390\/ijerph19137797","type":"journal-article","created":{"date-parts":[[2022,6,26]],"date-time":"2022-06-26T09:00:13Z","timestamp":1656234013000},"page":"7797","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Relationship between Oral Health Knowledge and Maternal Oral Health with Obstetric Risk and Breastfeeding"],"prefix":"10.3390","volume":"19","author":[{"given":"Silvia","family":"Serrano-S\u00e1nchez","sequence":"first","affiliation":[{"name":"Castilla-La Mancha Health Service, 45600 Talavera de la Reina, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jaime","family":"Gonz\u00e1lez-Gonz\u00e1lez","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Faculty of Health Sciences, University of Castilla-La Mancha, 45600 Talavera de la Reina, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3939-0299","authenticated-orcid":false,"given":"Beatriz","family":"Rodr\u00edguez-Mart\u00edn","sequence":"additional","affiliation":[{"name":"Department of Nursing, Physiotherapy and Occupational Therapy, Faculty of Health Sciences, University of Castilla-La Mancha, Avd\/Real F\u00e1brica de Sedas s\/n, 45660 Talavera de la Reina, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vanesa","family":"Mu\u00f1oz-Rodr\u00edguez","sequence":"additional","affiliation":[{"name":"Castilla-La Mancha Health Service, 45600 Talavera de la Reina, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sonia","family":"de las Heras-Corrochano","sequence":"additional","affiliation":[{"name":"Castilla-La Mancha Health Service, 45600 Talavera de la Reina, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7733-9788","authenticated-orcid":false,"given":"Juan Jos\u00e9","family":"Criado-Alvarez","sequence":"additional","affiliation":[{"name":"Department of Medical Sciences, Faculty of Health Sciences, University of Castilla-La Mancha, 45600 Talavera de la Reina, Spain"},{"name":"Department of Health, Institute of Health Sciences, 45600 Talavera de la Reina, Spain"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1389","DOI":"10.14219\/jada.archive.2008.0051","article-title":"The relationship of periodontal disease to diseases and disorders at distant sites: Communication to health care professionals and patients","volume":"139","author":"Lamster","year":"2008","journal-title":"J.
