Study of Early Adhesion of Some Oral Microflora Representatives to Basic Materials of Removable Dentures

Abstract

An increase in the number of removable denture constructions being produced leads to an increase in the number of complications, which, in turn, reduces the timing of the effective use of orthopedic structures. At present, the problem of treating prosthetic stomatitis and their prevention has not been resolved. Considering the current socio-economic situation, orthopedic treatment of the patients with removable dentures will be relevant for some more time. Microbiological studies of the ability of basic materials to adhere different types of microorganisms onto their surfaces were performed. There were used 7 different types of resins manufactured according to different technologies. Having performed a series of microbiological studies on the adhesive ability of basic materials, the following results were obtained. The control was glass, the average index of adhesion to which was 0.69±0.02. The greatest adhesive ability to various types of microorganisms was found in acrylic resins based on polymethyl methacrylate, namely auto-polymer resin Protacryl and resin Sinma. Accordingly, the smallest adhesive properties were seen in non-monomer resins, such as Polian, Nylon, Biocryl with adhesion indices of 0.75±0.04, 0.72±0.03, 0.78±0.03, respectively.
