TOXIC STOMATITIS AND INTERDISCIPLINARY APPROACH TO THE TREATMENT OF ELDERLY AND SENILE PATIENTS WITH PROSTHETIC STOMATITIS

Toxic reactions to acrylic dentures are largely determined by the physical and chemical composition, structure, mechanical properties and processes of destruction of acrylic plastic copolymers. This is their potential danger to humans. The main toxicogenic factor of acrylic plastic is the monomer. If the polymerization mode is violated, the amount of residual monomer increases sharply. The monomer is the cause of blastomogenesis. Under the influence of biological environments (saliva, microbial flora, pH of saliva, temperature conditions, etc.), as well as chewing loads, occlusal relationships of the plastic-plastic, plastic-metal systems, processes of structuring and destruction, migration, "sweating" of residual monomers, plasticizers, and dyes occur in the polymer composition. During chewing, an acrylic denture experiences various deformations, which leads to a disruption of the structure of its components. This, in turn, increases the amount of migrating monomer, which can cause the development of toxic stomatitis. Toxic stomatitis caused by the influence of metal dentures is manifested by characteristic subjective symptoms: burning of the tongue, sour taste, hypersalivation (less often dryness), paresthesia, and disturbance of the general nervous status. The degree of burning of the tongue varies among patients, and depends on the number of metal dentures in the mouth and the duration of their use.
