This three-year study describes the prevalence of T. forsythensis and its relationship to clinical loss of attachment (LOA) in a group of adolescents considered at risk of developing early chronic periodontitis. Adolescents with (LOA+) and without (LOA-) loss of attachment were examined at baseline and 1.5 and 3 yrs subsequently. On each occasion, attachment loss was measured on selected teeth, and the presence of T. forsythensis in their subgingival plaque samples was determined by PCR. T. forsythensis prevalence in LOA+ subjects at baseline (64%) increased to 82% and 86% on subsequent examinations. In contrast, prevalence of T. forsythensis in LOA- subjects was always significantly lower (25%, 36%, and 32%, respectively). The odds of loss of attachment were 8.16 times greater in subjects infected with T. forsythensis at each examination. These results suggest that T. forsythensis is strongly associated with loss of attachment in this adolescent population.<\/jats:p>","DOI":"10.1177\/154405910408300309","type":"journal-article","created":{"date-parts":[[2009,1,8]],"date-time":"2009-01-08T19:39:42Z","timestamp":1231443582000},"page":"232-235","source":"Crossref","is-referenced-by-count":30,"title":["Persistent Colonization with\n                    <i>Tannerella                   forsythensis<\/i>\n                    and Loss of Attachment in Adolescents"],"prefix":"10.1177","volume":"83","author":[{"given":"S.","family":"Hamlet","sequence":"first","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Ellwood","sequence":"additional","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M.","family":"Cullinan","sequence":"additional","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"H.","family":"Worthington","sequence":"additional","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Palmer","sequence":"additional","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P.","family":"Bird","sequence":"additional","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.","family":"Narayanan","sequence":"additional","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R.","family":"Davies","sequence":"additional","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G.","family":"Seymour","sequence":"additional","affiliation":[{"name":"Oral Biology and Pathology, School of Dentistry, University of\r               Queensland, St Lucia, 4072, Australia; and"},{"name":"Dental Health Unit, University of Manchester, Manchester, M15, 6SH,\r               UK;"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2004,3,1]]},"reference":[{"key":"CLEREHUGH-AND-LENNON-1984","unstructured":"Clerehugh V, Lennon MA -1984- The\n               attachment level as a measure of early periodontitis.
