The influence of base resin of removable dentures on the planktonic growth of individual representatives of oral microflora

Abstract

Introduction. Microbiological researches of the role of denture base materials in violation of the oral cavity micro ecology were conducted. Aim. Therefore, the purpose of research is to study the effect of different polymeric materials on denture bases, on the intensity of planktonic growth of resident and transient representatives of oral cavity microflora in a periodic culture on the basis of registration of its optical density. Material and methods. 7 types of denture base materials and their influence on the planktonic growth of microorganisms have been studied. Results. The planktonic growth of the S. oralis strain was suppressed by all base materials: SYNMA (by 35.5%), Bre.Flex (by 27.5%) and Protacryl-M (by 25.7%), in the smallest – Nylon (by 5.4%), Villacryl (by 9.5%). Conclusions. Through experimental research, we have proved the direct involvement of basic resin materials in changes in the oral cavity micro ecology and the process of occurrence of prosthetic stomatitis.
