The purpose of this longitudinal study was to evaluate the relationship between aspects of dietary intake, including milk and sucrose in coffee or tea (SCT), and root surface caries in older Japanese individuals.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>303 community\u2010dwelling older individuals (age 75\u00a0years) were enrolled for analysis. All participants underwent a dental examination at baseline and then annually from 2003 to 2008 (ie six times over a 5\u2010year period). A disease event was considered to have occurred when root surface caries was detected on a previously sound or nonexposed root surface. Over the observation period, disease events in each year were counted. Dietary habits during the preceding month were evaluated using a brief self\u2010administered diet history questionnaire (BDHQ) in 2003 and 2008. Poisson regression analysis performed crude and adjusted increment\u2010rate ratios (IRRs) for root surface caries and the intake of milk and SCT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The adjusted increment\u2010rate ratio (IRR) of the increment of root surface caries for participants in the highest SCT tertile was 1.72 (95%CI: 1.40\u20102.14) compared with the referent group. In addition, for the amount of milk intake, the adjusted IRR in the highest tertile was 0.63 (95% CI: 0.51\u20100.78) compared with the referent group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Much SCT and low milk intake were associated with the increment of root surface caries in community\u2010dwelling older people in Japan. These findings suggest that to help prevent root surface caries, community\u2010dwelling older people in Japan should consume adequate amounts of milk daily and limit their intake of SCT.<\/jats:p><\/jats:sec>","DOI":"10.1111\/cdoe.12602","type":"journal-article","created":{"date-parts":[[2020,12,1]],"date-time":"2020-12-01T02:20:10Z","timestamp":1606789210000},"page":"301-308","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Diet and root surface caries in a cohort of older Japanese"],"prefix":"10.1111","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0424-8228","authenticated-orcid":false,"given":"Akihiro","family":"Yoshihara","sequence":"first","affiliation":[{"name":"Division of Oral Science for Health Promotion Faculty of Dentistry &amp; Graduate School of Medical and Dental Science Niigata University Niigata City Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kana","family":"Suwama","sequence":"additional","affiliation":[{"name":"Division of Oral Science for Health Promotion Faculty of Dentistry &amp; Graduate School of Medical and Dental Science Niigata University Niigata City Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akane","family":"Miyamoto","sequence":"additional","affiliation":[{"name":"Division of Preventive Dentistry Faculty of Dentistry &amp; Graduate School of Medical and Dental Science Niigata University Niigata City Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Reiko","family":"Watanabe","sequence":"additional","affiliation":[{"name":"University of Niigata Prefecture Niigata City Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Ogawa","sequence":"additional","affiliation":[{"name":"Division of Preventive Dentistry Faculty of Dentistry &amp; Graduate School of Medical and Dental Science Niigata University Niigata City Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2020,11,30]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0528.2009.00461.x"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1155\/2011\/647168"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/aje\/kwf029"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1741-2358.2008.00244.x"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1177\/00220345880670060401"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.3945\/an.115.009365"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1177\/0022034518788283"},{"key":"e_1_2_8_9_1","volume-title":", Nutrition, and the Prevention of Chronic Diseases","author":"WHO","year":"2003"},{"key":"e_1_2_8_10_1","first-page":"e197","article-title":"Effect of bovine milk on Streptococcus mutans biofilm cariogenic properties and enamel and dentin demineralization","volume":"34","author":"Munoz\u2010Sandoval C","year":"2012","journal-title":"Pediatr Dent"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1159\/000339428"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1159\/000337390"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.3109\/00016357.2011.568962"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1590\/S0103-64402004000300004"},{"key":"e_1_2_8_15_1","volume-title":"Oral Health Surveys \u2013 Basic Methods","author":"WHO","year":"1997"},{"key":"e_1_2_8_16_1","unstructured":"SasakiS.Development and evaluation of dietary assessment methods using biomarkers and diet history questionnaires for individuals [paper in Japanese].
