They are attributed to its reservoir of polyphenols, particularly the catechin, epigallocatechin\u20103\u2010gallate. Owing to these beneficial actions, this traditional beverage was used in the management of chronic systemic diseases including cancer. Recently, it has been emphasized that the host immuno\u2010inflammatory reactions destroy the oral tissues to a greater extent than the microbial activity alone. Green tea with its wide spectrum of activities could be a healthy alternative for controlling these damaging reactions seen in oral diseases, specifically, chronic periodontitis, dental caries and oral cancer, which are a common occurrence in the elderly population.<jats:bold>Geriatr Gerontol Int 2014; 14: 238\u2013250.<\/jats:bold><\/jats:p>","DOI":"10.1111\/ggi.12194","type":"journal-article","created":{"date-parts":[[2013,11,22]],"date-time":"2013-11-22T03:58:59Z","timestamp":1385092739000},"page":"238-250","source":"Crossref","is-referenced-by-count":70,"title":["Green tea: A novel functional food for the oral health of older adults"],"prefix":"10.1111","volume":"14","author":[{"given":"Sumit","family":"Gaur","sequence":"first","affiliation":[{"name":"Department of Pedodontics and Preventive Dentistry Manipal College of Dental Sciences, Manipal University Manipal India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rupali","family":"Agnihotri","sequence":"additional","affiliation":[{"name":"Department of Periodontology Manipal College of Dental Sciences, Manipal University Manipal India"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,11,21]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/07315724.2000.10718972"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jada.2009.02.023"},{"key":"e_1_2_7_4_1","doi-asserted-by":"publisher","DOI":"10.1093\/jn\/133.7.2384"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/003335491012500202"},{"key":"e_1_2_7_6_1","doi-asserted-by":"publisher","DOI":"10.4103\/0972-124X.113064"},{"key":"e_1_2_7_7_1","doi-asserted-by":"publisher","DOI":"10.1016\/0091-7435(92)90041-F"},{"key":"e_1_2_7_8_1","doi-asserted-by":"publisher","DOI":"10.1093\/jn\/132.4.785"},{"key":"e_1_2_7_9_1","doi-asserted-by":"publisher","DOI":"10.4103\/0974-8490.89748"},{"key":"e_1_2_7_10_1","first-page":"968","article-title":"The second international scientific symposium on tea and human health","volume":"15","author":"Phipps RP","year":"1999","journal-title":"Nutrition"},{"key":"e_1_2_7_11_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2009.080510"},{"key":"e_1_2_7_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ypmed.2010.01.010"},{"key":"e_1_2_7_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.annepidem.2007.04.003"},{"key":"e_1_2_7_14_1","doi-asserted-by":"publisher","DOI":"10.1007\/s00394-012-0322-8"},{"key":"e_1_2_7_15_1","first-page":"675","volume-title":"Carranza's Clinical Periodontology","author":"Spackman SS","year":"2007"},{"key":"e_1_2_7_16_1","volume-title":"Functional Foods for Healthy Aging: A Toolkit for Registered Dietitians.
