The retrospective analysis of data on oral cavity clinical status in relation to microbiota species composition is presented. The research regards patients of different age, with and without congenital malformation, pretreatment assessed for occurrence of pathological changes in the masticatory system. Samples of the swabs collected from each patient (from dental plaque, periodontium and dental pockets) were used for identification of oral protozoans in wet slides and stained preparations; additionally, transmission electron microscope examination was performed. The material was used for in vitro cultures to identify bacteria strains. Clinically, intensity of tissue deteriorations was higher in patients with a congenital disease. Alive Trichomonas tenax and Entamoeba gingivalis, species with confirmed pathogenic impact on oral cavity and neighboring structures, were detected with higher prevalence in older patients. Enterococci, Staphylococcus aureus, various Enterobacteriaceae were more frequently detected in patients with somatic and mental retardations; in mouths of those patients, Klebsiella pneumonia and Pseudomonas aeruginosa opportunistic strains occurred. Masticatory system abnormalities favor colonization of oral cavity by exogenous species and dissemination of infections, especially dangerous for patients with congenital diseases. Oral microbiota assessment and preventive measures may be helpful to avoid subsequent peri-surgery complications.

In this research, a comparative analysis of results of investigations involving different human populations, in terms of a relation between the oral cavity health and the species composition of mouth microbiota is reported. The purpose of this analysis was to identify and assess microorganisms that could cause health complications in patients with neoplasm requiring dental problem-related surgical management. The patients with the oral cancer surgically treated and those without neoplasm were assessed for their oral health: status of teeth, gingiva, periodontium, and occurrence of inflammatory processes. From each patient, microorganisms isolated of periodontium, dental plaque, and dental pocket swabs were identified in wet and stained microscopic preparations; standard microbiology in vitro techniques were also applied to determine the fungal and bacterial strains. The comparative analysis of results of direct microscopic examinations and in vitro cultures assessment indicated significant differences in prevalences of fungi, parasitic oral protozoans and bacteriae in particular patient’s groups. Yeast-like fungi belonging to Candida genus, mostly of C. albicans group, were identified in 93.75% patients with the oral cancer, while in 25% of individuals assessed without neoplasm. E. gingivalis amoebae were only found in 12.5% patients with the serious disease; no trichomonads were detected in all patients analyzed. Among bacteria species, potentially pathogenic Enterobacteriaceae were found in the patients with oral cancer. The pronounced shift in the microbiota species composition in the patients who needed prolonged treatment due to oral cavity cancer, compared to other generally healthy persons has been showed in this analysis.

Twenty five women (21 to 50 years old) with genetic diseases (phenylketonuria, Down’s syndrome, achondroplasia, epilepsy), patients of the II Maxillo-Facial Surgery Clinic of the Medical University of Warsaw, were examined for the pre-treatment status of the oral cavity and the occurrence of oral protozoans, Entamoeba gingivalis and/or Trichomonas tenax. On the basis of the clinical characteristics and light and transmission electron microscopic examination, relationship between periodontal condition and presence of the oral protozoans were analysed and factors which may play the main role in the maintenance of the infection in these patients were determined. The highest prevalence of infection with E. gingivalis and T. tenax was noted in the 41-50 year age group in which more than 88% of the patients were infected. In 11 among of 20 of the cases with periodontal disease, infection with T. tenax, and/or E. gingivalis occurred. In 10 among of 16 of the individuals with limited mobility the oral protozoans was present. Our studies indicate that age as well as limited mobility of the patients examined resulting in difficulties with maintaining of good hygiene of oral cavity may play an important role in occurrence of infection with the oral protozoans and inflammatory processes in gingiva and periodontium.

The aim of this study was to compare the oral cavity status with the species composition of microorganisms colonizing the mouth of patients with or without systemic diseases. Seventy-seven men and women, 19 to 65-years-old, of four groups: hemodialyzed patients (HD), kidney allograft recipients (Tx), congenitally disordered (Cd) and control (C) patients (without systemic diseases) were examined clinically for the oral cavity status and the microorganisms occurring in the mouth were identified. Swabs and samples taken from dental plaques, pockets and periodontium were used for light and electron microscopical studies as well as for protozoan, bacterial and fungal cultures. Entamoeba gingivalis and Trichomonas tenax were found in the HD, Tx, Cd and C groups (top prevalence 14, 14, 87.5 and 25%, respectively); free-living amoebae (with some features of Acanthamoeba sp.) also occurred in several cases. Staphylococcus aureus bacteria were found in 66% of Cd patients infected with the protozoans. Numerous fecal bacteria and/or fungi Candida albicans have been observed in 41-51-year-old Cd and HD patients. In all patient groups, it was the 41-51-year-olds who showed the highest prevalence of protozoans, bacteria and fungi. The results indicate that metabolic disabilities favour pathological changes in periodontal tissues and may influence the species composition of mixed protozoan, bacterial and/or fungal infections in various ways, in patients with different systemic diseases.
