However, the effects of different tea types on oral health remain unclear. Therefore, this study aimed to determine the association between residual teeth and consumption habits of different types of tea (green tea, black tea, oolong tea, and scented tea) in older adults.We conducted a secondary analysis using data from the Chinese Longitudinal Healthy Longevity Survey in 2018. In a sample of 6,387 older adults, we performed logistic regression analysis to examine the relationship between persistent tea consumption and oral health according to sex and brushing frequency. The indices for particularly healthy oral health and relative health were set at more than 20 teeth and more than 10 teeth, respectively.The study included 2,725 males and 3,662 females, both aged 65 and older. Among individuals with more than 20 teeth, drinking green tea significantly improved oral health in men (adjusted odds ratio [ORs]: 1.377; 95% confidence interval [CI]: 1.082–1.752) and drinking black tea significantly improved the oral health of women (ORs: 2.349, 95%CI: 1.028–5.366). In the daily brushing group, green tea had a significant beneficial effect on increasing the number of teeth in men and black tea had a significant beneficial effect in women. Among individuals with more than 10 teeth, drinking green tea significantly improved oral health in men (ORs: 1.539; 95% CI: 1.209–1.959) and drinking green tea and scented tea significantly improved the oral health of women (ORs: 1.447, 95%CI: 1.052–1.991; ORs: 1.948, 95%CI: 1.137–3.340). In the daily brushing group, consumption of green tea and black tea had significant beneficial effects on increasing the number of teeth in men, whereas that of green tea, black tea, and scented tea had significant beneficial effects in women.Long-term green tea consumption in males and black tea consumption in females were significantly associated with maintaining functional dentition (≥20 teeth). Similarly, long-term green tea consumption in males and green tea and scented tea consumption in females were associated with avoiding severe tooth loss (≥10 teeth). Furthermore, in the daily tooth brushing group, long-term consumption of black tea was associated with avoiding severe tooth loss in both sexes. However, tea consumption alone had no effect on oral health without good brushing habits.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10006_dissertation_number_12":{"attribute_name":"学位授与番号","attribute_value_mlt":[{"subitem_dissertationnumber":"甲第1003号"}]},"item_10006_relation_14":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.1186/s12889-024-17874-7","subitem_relation_type_select":"DOI"}},{"subitem_relation_name":[{"subitem_relation_name_text":"BMC Public Health. 2024, 24(1), 400."}]}]},"item_10006_rights_13":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"© 2024 The Author(s)","subitem_rights_language":"en"},{"subitem_rights":"Creative Commons Attribution 4.0 International","subitem_rights_language":"en","subitem_rights_resource":"https://creativecommons.org/licenses/by/4.0/"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"open access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_abf2"}]},"item_creator":{"attribute_name":"作成者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"黄, 哲麒","creatorNameLang":"ja"},{"creatorName":"コウ, テツキ","creatorNameLang":"ja-Kana"},{"creatorName":"Huang, Zheqi","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-06-01"}],"filename":"kou_1003_ab.pdf","filesize":[{"value":"238 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"論文内容要旨・審査結果要旨","objectType":"abstract","url":"https://osaka-dent.repo.nii.ac.jp/record/2000115/files/kou_1003_ab.pdf"},"version_id":"470106bd-1180-4ece-afa6-32bb6dd2edba"},{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-01-31"}],"filename":"kou_1003_txt.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"学位論文","objectType":"fulltext","url":"https://osaka-dent.repo.nii.ac.jp/record/2000115/files/kou_1003_txt.pdf"},"version_id":"2d97dc8b-1e38-4603-a4cc-d44d6ab51d5f"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Tea type","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Number of teeth","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Chinese Longitudinal Healthy Longevity  Survey","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Older adults","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Brushing frequency","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"doctoral thesis","resourceuri":"http://purl.org/coar/resource_type/c_db06"}]},"item_title":"Association between tea types and number of teeth: a cross-sectional study of the Chinese Longitudinal Healthy Longevity Survey","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Association between tea types and number of teeth: a cross-sectional study of the Chinese Longitudinal Healthy Longevity Survey","subitem_title_language":"en"},{"subitem_title":"お茶の種類と口腔残存歯数の関係：CLHLS調査の横断研究","subitem_title_language":"ja"}]},"item_type_id":"10006","owner":"18","path":["65"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-01"},"publish_date":"2024-06-01","publish_status":"0","recid":"2000115","relation_version_is_last":true,"title":["Association between tea types and number of teeth: a cross-sectional study of the Chinese Longitudinal Healthy Longevity Survey"],"weko_creator_id":"18","weko_shared_id":-1},"updated":"2025-02-02T07:28:37.072184+00:00"}
