Microbiological samples of cheek mucosa and the dorsum of the tongue were taken from all subjects. In addition, sulcus samples were taken from the dentate group. All samples were analysed using a bacterial DNA\u2010specific polymerase chain reaction.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> All the pathogens studied were detected in dentate and edentulous subjects. When cheek and tongue samples were combined, <jats:italic>C. rectus, A. actinomycetemcomitans<\/jats:italic> and <jats:italic>E. corrodens<\/jats:italic> presented with a similar prevalence in both groups, whereas the other species were more prevalent specifically in the dentate group (<jats:italic>P<\/jats:italic>&lt;0.05).
