Following a 9\u2010month period, 9 LIP patients were divided into 2 groups based upon attachment loss, progressing and non\u2010progressing. Both groups received scaling, root planing, and modified Widman flaps. Clinical and microbiological data were obtained at baseline, following the observation period, and at 6 and 12 months post\u2010treatment. At 6 and 12 months post\u2010treatment significantly more cocci were persistent in the non\u2010progressing group than in the progressing group. <jats:italic>Actinobacillus actinomycetemcomitans<\/jats:italic> was also more frequently isolated in the progressing group than in the non\u2010progressing group initially and following the 9\u2010month observation period. Also after treatment, <jats:italic>A. actinomycetemcomitans<\/jats:italic> recolonized earlier in the progressing group than in the non\u2010progressing group. These studies suggest that A. actinomycetemcomitans may play a role in disease progression in LIP; however, they do not eliminate the possibility that other organisms may also play a role, since <jats:italic>A. actinomycetemcomitans<\/jats:italic> was not detected in all of the patients in whom disease progressed. <jats:italic>J Periodontol 1992; 63:806\u2013811<\/jats:italic>.<\/jats:p>","DOI":"10.1902\/jop.1992.63.10.806","type":"journal-article","created":{"date-parts":[[2012,3,21]],"date-time":"2012-03-21T01:41:23Z","timestamp":1332294083000},"page":"806-811","source":"Crossref","is-referenced-by-count":10,"title":["Longitudinal Monitoring for Disease Progression of Localized Juvenile Periodontitis"],"prefix":"10.1002","volume":"63","author":[{"given":"K.J.","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D.K.","family":"Kim","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C.P.","family":"Chung","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.","family":"Son","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[1992,10]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.1992.63.10.806","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T11:14:57Z","timestamp":1760872497000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.1992.63.10.806"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1992,10]]},"references-count":0,"journal-issue":{"issue":"10","published-print":{"date-parts":[[1992,10]]}},"alternative-id":["10.1902\/jop.1992.63.10.806"],"URL":"https:\/\/doi.org\/10.1902\/jop.1992.63.10.806","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"value":"0022-3492","type":"print"},{"value":"1943-3670","type":"electronic"}],"subject":[],"published":{"date-parts":[[1992,10]]}}}
