A total of 508 oral bacterial samples were taken from 10 periodontally healthy adults (PH), 11 adult Periodontitis patients (AP), and 6 localized juvenile Periodontitis patients (LJP). From each subject, samples of supra\u2013 and subgingival plaque were obtained from six to eight teeth as well as samples from buccal mucosa, lateral and dorsal surfaces of tongue, tonsil, and saliva. <jats:italic>E<\/jats:italic>. <jats:italic>corrodens<\/jats:italic> was cultured from 70% of healthy subjects and 100% of Periodontitis patients. Dental plaque appears to be the main oral ecological niche of <jats:italic>E<\/jats:italic>. <jats:italic>corrodens<\/jats:italic> in PH subjects since it was found in, respectively, 26% and 31% of supra\u2013 and subgingival plaque samples and rarely found in other oral sites in these subjects. It was found in 59% of both supra\u2013 and subgingival plaque samples from AP subjects, as well as 48% and 64% of supra\u2013 and subgingival plaque samples of LJP subjects. In contrast to healthy subjects, <jats:italic>E<\/jats:italic>. <jats:italic>corrodens<\/jats:italic> was found on the buccal mucosa, tongue, tonsil and in the saliva of patients with Periodontitis. The microorganism constituted, on average, 1% to 2% of the total cultivable bacteria in supra\u2013 and subgingival plaque samples. The prevalence of <jats:italic>E<\/jats:italic>. <jats:italic>corrodens<\/jats:italic> in plaque samples was higher in AP and LJP subjects and was significantly different from PH subjects. Within the AP group, the prevalence of <jats:italic>E<\/jats:italic>. <jats:italic>corrodens<\/jats:italic> in subgingival plaque is significantly higher from sites with GI \u2265 2. These data suggest that <jats:italic>E<\/jats:italic>. <jats:italic>corrodens<\/jats:italic> is an indigenous oral microorganism which may be an opportunistic pathogen associated with gingival inflammation.
