The subjects were selected based on the presence or absence of attachment loss at baseline. The attachment level was assessed clinically at baseline and at a 6\u2010year follow\u2010up examination, and the presence of 7 bacterial species was assessed at follow\u2010up using DNA probes. The individuals were classified into generalized, localized, incidental EOP, and no\u2010periodontitis groups based on the extent and severity of attachment loss; and classified as having rapid, moderate, slow, and no progression based on the rate of periodontal progression during the 6 preceding years. In the EOP groups there were significantly higher percentages of individuals with detectable levels of <jats:italic>Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum, Campylobacter rectus, and Treponema denticola<\/jats:italic>. In addition, the EOP group had significantly higher levels of these 5 microorganisms compared to the no\u2010periodontitis group. There were also higher percentages of individuals with these species and higher levels of bacteria in the group showing disease progression than the group without progression. In a descending order of importance, <jats:italic>P. gingivalis, T. denticola<\/jats:italic>, and <jats:italic>P. intermedia<\/jats:italic> were the microorganisms significantly associated with the generalized and\/or rapidly progressing disease. <jats:italic>F. nucleatum<\/jats:italic> and <jats:italic>C. rectus<\/jats:italic> were also associated with EOP, but to a lesser degree. In the present population <jats:italic>Actinobacillus actinomycetemcomitans<\/jats:italic> was not significantly associated with EOP, though it was recovered more often from subjects with localized EOP. <jats:italic>Eikenella corrodens<\/jats:italic> was present equally in subjects with and without disease. The results show that several bacterial species are associated with EOP, and that <jats:italic>P. gingivalis<\/jats:italic> and <jats:italic>T. denticola<\/jats:italic> are of particular importance and may play a significant role in the more severe and progressive forms of EOP. <jats:italic>J Periodontol 1997;68:973\u2013981<\/jats:italic>.<\/jats:p>","DOI":"10.1902\/jop.1997.68.10.973","type":"journal-article","created":{"date-parts":[[2012,3,20]],"date-time":"2012-03-20T17:33:41Z","timestamp":1332264821000},"page":"973-981","source":"Crossref","is-referenced-by-count":98,"title":["Putative Periodontal Pathogens in Subgingival Plaque of Young Adults With and Without Early\u2010Onset Periodontitis"],"prefix":"10.1002","volume":"68","author":[{"given":"Jasim M.","family":"Albandar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L.
