This study investigated the association between vitamin D levels and dental caries in older adults using data from the United States National Health and Nutrition Examination Survey from 2011 to 2016. Methods: Data were analyzed from 2723 participants aged 65 years and older who completed both dental examinations and serum 25(OH)D tests. Dental caries assessments included the decayed, missing, and filled teeth (DMFT) index and the presence of untreated dental caries. Vitamin D levels were measured as serum 25(OH)D concentrations and categorized as severely deficient (&lt;25 nmol\/L), deficient (25\u201349.9 nmol\/L), insufficient (50\u201374.9 nmol\/L), and normal (\u226575 nmol\/L). Logistic regression and Poisson regression models were used to assess the association between vitamin D levels and dental caries, adjusting for demographic factors. Results: The mean DMFT score was 17.73 \u00b1 8.34, with 35.1% of participants having untreated dental caries. Vitamin D deficiency was associated with a 1.44 times higher likelihood of untreated caries (95% CI: 1.15, 1.81), which weakened after adjustment for demographic factors (adjusted OR: 1.23, 95% CI: 0.97, 1.55). Severe vitamin D deficiency correlated with a 1.13 times higher DMFT score (95% CI: 1.06, 1.20), with the association remaining similar after adjustment (adjusted RR: 1.12, 95% CI: 1.05, 1.20). Significant differences in vitamin D levels were observed across gender, race\/ethnicity, and country of birth. Conclusions: This study suggests the potential importance of adequate vitamin D levels for maintaining dental health among older adults. Vitamin D deficiency is associated with a higher risk of poorer DMFT scores. Public health strategies that include vitamin D screening and supplementation, particularly for high-risk groups, may improve oral health outcomes in the older adult population. Further research is needed to elucidate the mechanisms by which vitamin D influences dental health and the potential for vitamin D supplementation to reduce the burden of dental caries in older adults.<\/jats:p>","DOI":"10.3390\/nu16142307","type":"journal-article","created":{"date-parts":[[2024,7,18]],"date-time":"2024-07-18T10:39:26Z","timestamp":1721299166000},"page":"2307","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["The Association of Vitamin D Levels and Dental Caries in Older Adults: A Cross-Sectional Study"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2827-3740","authenticated-orcid":false,"given":"Man","family":"Hung","sequence":"first","affiliation":[{"name":"College of Dental Medicine, Roseman University of Health Sciences, South Jordan, UT 84095, USA"},{"name":"Division of Public Health, University of Utah, Salt Lake City, UT 84112, USA"},{"name":"Department of Orthopaedics, University of Utah, Salt Lake City, UT 84112, USA"},{"name":"Department of Population Health Sciences, University of Utah, Salt Lake City, UT 84112, USA"},{"name":"School of Business, University of Utah, Salt Lake City, UT 84112, USA"},{"name":"The Wharton School, University of Pennsylvania, Philadelphia, PA 19104, USA"},{"name":"Huntsman Cancer Institute, Salt Lake City, UT 84112, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7277-1291","authenticated-orcid":false,"given":"Amir","family":"Mohajeri","sequence":"additional","affiliation":[{"name":"College of Dental Medicine, Roseman University of Health Sciences, South Jordan, UT 84095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mahsa","family":"Sadri","sequence":"additional","affiliation":[{"name":"College of Dental Medicine, Roseman University of Health Sciences, South Jordan, UT 84095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elahe","family":"Khodabandeh","sequence":"additional","affiliation":[{"name":"College of Dental Medicine, Roseman University of Health Sciences, South Jordan, UT 84095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ibrahim","family":"Zeitoun","sequence":"additional","affiliation":[{"name":"College of Dental Medicine, Roseman University of Health Sciences, South Jordan, UT 84095, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martin","family":"Lipsky","sequence":"additional","affiliation":[{"name":"College of Dental Medicine, Roseman University of Health Sciences, South Jordan, UT 84095, USA"},{"name":"Institute on Aging, Portland State University, Portland, OR 97201, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,18]]},"reference":[{"key":"ref_1","unstructured":"Rathee, M., and Sapra, A.
