The present study evaluates the presence of dental erosion in obese patients before and after bariatric surgery using the BEWE (basic erosive wear examination) scoring system. A total of 62 patients with severe obesity were included in the analysis, 31 in the control group (without bariatric surgery) and 31 in the surgery group (after bariatric surgery). BEWE scores did not vary between groups. Vitamin D deficiency was detected in 19 patients in the control group and three in the surgery group (p &lt; 0.001). The serum calcium and vitamin D values were significantly higher in the surgery group (p = 0.003, p &lt; 0.001 consecutively). All patients after bariatric surgery showed compliance with supplements, including vitamin D and calcium daily. Patients after bariatric surgery were less likely to drink soft drinks regularly (p = 0.026). Obese patients, before or after bariatric surgery, are at risk for erosive dental wear. However, with sufficient education prior to surgery and consistent intake of vitamin and mineral supplements, significant erosive dental wear after bariatric surgery could be avoided. Regular dental examination should be included in the check-up and follow-up program.<\/jats:p>","DOI":"10.3390\/jcm10214902","type":"journal-article","created":{"date-parts":[[2021,10,24]],"date-time":"2021-10-24T22:06:16Z","timestamp":1635113176000},"page":"4902","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Dental Erosion in Obese Patients before and after Bariatric Surgery: A Cross-Sectional Study"],"prefix":"10.3390","volume":"10","author":[{"given":"Cui","family":"Yang","sequence":"first","affiliation":[{"name":"Department of Surgery, Medical Faculty Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Frederik Johannes","family":"Hammer","sequence":"additional","affiliation":[{"name":"Department of Surgery, Medical Faculty Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany"},{"name":"Faculty of Dentistry, University of Heidelberg, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4591-1046","authenticated-orcid":false,"given":"Christoph","family":"Reissfelder","sequence":"additional","affiliation":[{"name":"Department of Surgery, Medical Faculty Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mirko","family":"Otto","sequence":"additional","affiliation":[{"name":"Department of Surgery, Medical Faculty Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Georgi","family":"Vassilev","sequence":"additional","affiliation":[{"name":"Department of Surgery, Medical Faculty Mannheim, University of Heidelberg, Theodor-Kutzer-Ufer 1-3, 68167 Mannheim, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,24]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"5","DOI":"10.1002\/oby.20662","article-title":"Eight-Year Weight Losses with an Intensive Lifestyle Intervention: The Look AHEAD Study","volume":"22","author":"Wadden","year":"2014","journal-title":"Obesity"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"e1466","DOI":"10.1590\/0102-672020190001e1466","article-title":"Bariatric surgery impact on gastroesophageal reflux and dental wear: A systematic review","volume":"32","author":"Castilho","year":"2019","journal-title":"Arquivos Brasileiros de Cirurgia Digestiva"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"77","DOI":"10.1016\/j.jdent.2019.02.005","article-title":"Erosive Tooth Wear and Caries Experience in Children and Adolescents with Obesity","volume":"83","author":"Tschammler","year":"2019","journal-title":"J.
