摘要：

A complete loss of teeth may eliminate some pathogenic bacteria for lack of a suitable habitat for colonization. The occurrence of Actinobacillus actinomycetemcomitans, black-pigmented Bacteroides, mutans streptococci, lactobacilli and yeasts was investigated in 51 edentulous subjects with complete denture(s); mean age 74 years (range 44-92 years). None of the subjects had received antibiotics during the preceding 6 months. Four swab samples per subject were taken from the fitting surface of the upper denture, from the palate, buccal mucosae and dorsum of the tongue. At least 0.5 ml of stimulated saliva was collected into a sterile tube. The samples were cultivated aerobically and anaerobically using nonselective and selective media. A. actinomycetemcomitans was not found in any of the samples. Black-pigmented Bacteroides were found in 49 (96%) and yeasts in 25 (49%) of the subjects. Of the 49 saliva samples, 41 (84%) yielded mutans streptococci and 45 (92%) lactobacilli. In contrast to black-pigmented Bacteroides, mutans streptococci and lactobacilli, A. actinomycetemcomitans may not belong to the normal oral flora of edentulous subjects wearing dentures.
