Antral secretions from 67 patients with dental sinusitis were examined bacteriologically. The results were summerized as follows:1) From the 67 patients, 22 species and 113 strains were isolated.2) Mixed infections with two, three and four species were found in 33 of the total cases. Fourteen of them were a mixture of Staphylococcus aureus and Esherichia coli. Twelve showed a mixture of aerobic and anaerobic bacteria.3) Aerobic bacteria were isolated with higher incidence than anaerobic bacteria. Aerobic bacteria were isolated and composed of 17 species and 94 strains. Staphylococcus aureus was the most frequent species, followed by α-Streptococcus, Esherichia coli and Pseudomonas aeruginosa. In anaerobic bacteria, 5 species and 19 strains were isolated in descending order of Peptococcus, Veillonella and Peptostreptococcus.4) From 49 patients in the acute stage, 19 species and 87 strains were isolated, Staphylococcus aureus was the most frequent species. From 18 patients in the chronic stage, 15 species and 26 strains were isolated, Pseudomonas aeruginosa was the most frequent species and Staphylococcus aureus had a low incidence.5) No difference was found between bacteriological findings in dental sinusitis and nasal sinusitis. In other words, the bacteria participating in this disease are approximately similar to those in nasal sinusitis. No special bacteria are present in this disease.
