[Trichomonosomycosis of the oral cavity].

Protozoa and fungi of the oral cavity, although frequently occuring and connected with considerable clinical adverse effects, are as yet insufficiently known. The aims of the study were to estimate the prevalence of common invasions of Trichomonas tenax and fungi, to associate the symptoms with the diagnosis of trichomonosis complicated by mycosis and to determine trichomonacidal properties of ornidazole, tinidazole and metronidazole. 936 dentist patients with different diagnoses were included into the study. The collected material consisted of rinsings, with simultaneous application of selective media, different for protozoa and for fungi 6ultures. Among the examined patients T. tenax was found in 90 cases including 85 cases where it occurred together with fungi (11 species), on the basis of which the diagnosis of trichomonosomycosis of the oral cavity was established. It was the most often in patients with leukoplakia and Lichen Wilsoni. We received a statistically significant association (0.001 <p<0.01) for T. tenax with fungi and xerostomia, burning sensation, periodontal pockets and denuded teeth. Trichomonas tenax was not found in any patiem with caries and with aphthe recidivans.
