A comprehensive systematic literature search was performed in four databases (PubMed, CINAHL, Dentistry and Oral Sciences Source, and Embase) for literature from January 2000 to May 2020. Both observational and intervention studies were screened for eligibility. Two reviewers independently screened the search results to identify potential eligible studies, and assessed the methodological quality of the full-text studies. A total of 3240 potential studies were identified. After judgement for relevance, 10 studies (cross-sectional (n = 9), prospective cohort (n = 1)) met the inclusion criteria. Three studies described malnourished participants as having fewer teeth, or functional (tooth) units (FTUs), compared to well-nourished participants. Four studies reported soft tissue problems in malnourished participants, including red tongue with blisters, and dry or cracked lips. Subjective oral health was the topic in six studies, with poorer oral health and negative self-perception of oral health in malnourished elderly participants. There are associations between (at risk of) malnutrition and oral health in older people, categorized in hard and soft tissue conditions of the mouth, and subjective oral health. Future research should be focused on longitudinal cohort studies with proper determination of malnutrition and oral health assessments, in order to evaluate the actual association between malnutrition and oral health in older people.<\/jats:p>","DOI":"10.3390\/nu13103584","type":"journal-article","created":{"date-parts":[[2021,10,13]],"date-time":"2021-10-13T21:48:39Z","timestamp":1634161719000},"page":"3584","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":92,"title":["The Association between Malnutrition and Oral Health in Older People: A Systematic Review"],"prefix":"10.3390","volume":"13","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6195-0227","authenticated-orcid":false,"given":"Yne","family":"Algra","sequence":"first","affiliation":[{"name":"Research Group Innovations in Preventive Health Care, HU University of Applied Sciences, 3584 Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elizabeth","family":"Haverkort","sequence":"additional","affiliation":[{"name":"Research Group Innovations in Preventive Health Care, HU University of Applied Sciences, 3584 Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wilhelmina","family":"Kok","sequence":"additional","affiliation":[{"name":"Research Group Innovations in Preventive Health Care, HU University of Applied Sciences, 3584 Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faridi van","family":"Etten-Jamaludin","sequence":"additional","affiliation":[{"name":"Research Support, Medical Library AMC, Amsterdam UMC-Location AMC, University of Amsterdam, 1105 Amsterdam, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Liedeke van","family":"Schoot","sequence":"additional","affiliation":[{"name":"Research Group Innovations in Preventive Health Care, HU University of Applied Sciences, 3584 Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9360-0870","authenticated-orcid":false,"given":"Vanessa","family":"Hollaar","sequence":"additional","affiliation":[{"name":"Research Group Nutrition, Dietetics and Lifestyle, HAN University of Applied Sciences, 6525 Nijmegen, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0917-3413","authenticated-orcid":false,"given":"Elke","family":"Naumann","sequence":"additional","affiliation":[{"name":"Research Group Nutrition, Dietetics and Lifestyle, HAN University of Applied Sciences, 6525 Nijmegen, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5693-0811","authenticated-orcid":false,"given":"Marian de van der","family":"Schueren","sequence":"additional","affiliation":[{"name":"Research Group Nutrition, Dietetics and Lifestyle, HAN University of Applied Sciences, 6525 Nijmegen, The Netherlands"},{"name":"Division of Human Nutrition and Health, Wageningen University and Research, 6708 Wageningen, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katarina","family":"Jerkovi\u0107-\u0106osi\u0107","sequence":"additional","affiliation":[{"name":"Research Group Innovations in Preventive Health Care, HU University of Applied Sciences, 3584 Utrecht, The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,13]]},"reference":[{"key":"ref_1","unstructured":"Suzman, R., and Beard, J.
