According to the logistic regression analysis, factors related to DDE prevalence were advanced maternal age, gestational age\u2009&lt;\u200928\u00a0weeks, birth weight\u2009&lt;\u20091000\u00a0g, 1\u00a0min APGAR score\u2009&lt;\u20097, and hospitalization period\u2009&gt;\u20092\u00a0months, which were significantly higher by 2.91, 5.53, 7.63, 10.02, and 4.0 times, respectively. According to regression analysis with generalized linear models, the PDDE scores were approximately 7.65, 4.96, and 15.0 points higher in premature children diagnosed with bronchopulmonary dysplasia, intraventricular hemorrhage, and necrotizing enterocolitis, respectively. When endotracheal intubation was performed, the PDDE score was 5.06 points higher. The prevalence of PDDE was primarily observed bilaterally in the maxillary anterior teeth. Extremely preterm infants showed significantly delayed tooth eruption, suggesting that the influence of gestational age on dental development rates. Identifying the factors related to DDE in premature children can inform early dental interventions to support the oral health of high-risk children.<\/jats:p>","DOI":"10.1038\/s41598-024-52525-2","type":"journal-article","created":{"date-parts":[[2024,1,24]],"date-time":"2024-01-24T15:04:26Z","timestamp":1706108666000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Natal factors affecting developmental defects of enamel in preterm infants: a prospective cohort study"],"prefix":"10.1038","volume":"14","author":[{"given":"Shang-yon","family":"Park","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Su Jin","family":"Jeong","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jung Ho","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeong Eun","family":"Shin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jae-Ho","family":"Lee","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chung-Min","family":"Kang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2024,1,24]]},"reference":[{"key":"52525_CR1","first-page":"647","volume":"10","author":"TM Randis","year":"2008","unstructured":"Randis, T.
