Four zones of plaque were described according to their location along the tooth surface. Supragingivally, cocci, filamentous bacilli and \u201ccorncob\u201d formations were seen. Fusiform bacilli colonized the surface of supragingival plaque on the root surface. Subgingival sites, particularly apical areas, had numerous spirochetes adherent to the plaque surface as well as directly to the cementum surface. Microcolonies of bacteria, probably Mycoplasma, could be seen in the subgingival plaque. The findings of a potentially pathogenic plaque, attached subgingival spirochetes and microcolony formation may have important therapeutic and research implications.<\/jats:p>","DOI":"10.1902\/jop.1981.52.8.442","type":"journal-article","created":{"date-parts":[[2012,3,21]],"date-time":"2012-03-21T16:16:09Z","timestamp":1332346569000},"page":"442-446","source":"Crossref","is-referenced-by-count":12,"title":["Scanning Electron\u2010Microscopy of Plaque in Papillon\u2010Lef\u00e8vre Syndrome"],"prefix":"10.1002","volume":"52","author":[{"given":"Jorge","family":"Jung","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"suffix":"Jr.","given":"Fermin A.","family":"Carranza","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael G.","family":"Newman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[1981,8]]},"container-title":["Journal of Periodontology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/pdf\/10.1902\/jop.1981.52.8.442","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,19]],"date-time":"2025-10-19T11:23:31Z","timestamp":1760873011000},"score":1,"resource":{"primary":{"URL":"https:\/\/aap.onlinelibrary.wiley.com\/doi\/10.1902\/jop.1981.52.8.442"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1981,8]]},"references-count":0,"journal-issue":{"issue":"8","published-print":{"date-parts":[[1981,8]]}},"alternative-id":["10.1902\/jop.1981.52.8.442"],"URL":"https:\/\/doi.org\/10.1902\/jop.1981.52.8.442","archive":["Portico"],"relation":{},"ISSN":["0022-3492","1943-3670"],"issn-type":[{"type":"print","value":"0022-3492"},{"type":"electronic","value":"1943-3670"}],"subject":[],"published":{"date-parts":[[1981,8]]}}}
