IDENTIFICATION OF PATHOGENIC RESPIRATORY BACTERIA IN DENTAL PLAQUE, PHARYNX, AND NASOPHARYNX IN CLINICALLY HEALTHY POPULATION AND HOSPITALIZED PATIENTS

Background: The oral cavity is a moist environment which promotes the development of bacteria accumulation called dental plaque. When oral pH is altered there is a change in salivary secretion, which favors the colonization of microorganisms. Methods: 50 individuals were included, divided into two groups I:hospitalized individuals. Demographic information was collected from each individual and an odontological assessment was performed. Bacterial cultures of dental plaque, pharynx, nasopharynx were made and saliva pH was measured. Results: The oral health status of all individuals was determined by a specialist. In group I: it was found that the risk of periodontal disease was 5.5 higher, halitosis, change in color of the mucosa, and saliva pH was 2.2, 5 and 3.9 higher than group II. 150 bacterial cultures were processed, bacteria such as: K. pneumoniae, S. aureus, S. pneumoniae, S. pyogenes among others were isolated in both groups. The possibility of a pathogen in dental plaque was 11 times higher in group I. Conclusions: We observed that when oral mucosa is altered, some microorganisms take advantage of this imbalance to adhere to the mucosa, as a first step in colonization and infection.
