Estimate the composition of salivary microflora in individuals who use removable and fixed dental orthopedic appliances, taking into account the age of the patients and the material used as a base for the prosthesis and implant. Investigation of saliva by means of polymerase chain reaction method (PCR) was performed in 43 patients. A group of patients under 50 years using fixed prostheses included 22 people, and one of patients older than 50 using removable prostheses included 21 people. The base material of the removable orthopedic appliances was made of acrylic resin, and one of fixed prosthetic constructions was made of metal-ceramics.
In the saliva of individuals using removable orthopedic appliances, incidence of Streptococcus spp., Staphylococcus spp., Gardnerella vaginalis, Prevotella bivia, Porphyromonas spp., Sneathia spp., Leptotrichia spp., Fusobacterium spp., Megasphaera spp., Veillonella spp., Dialister spp. and the degree of contamination of saliva by the microorganisms listed above was higher than in those using fixed orthopedic appliances. We observed a higher adhesion of microorganisms to acrylic resin than to metal-ceramics.
