Novel Artificial Biofilm Equivalent for Denture Surfaces: A Pilot Study

The microbial population of the dental biofilm is embedded in an extracellular matrix that contains organic polymers such as polysaccharides. promotes adhesion on surfaces prostheses and acts a protective barrier. Thus, breakdown crucial for effective mechanical removal by brushing. purpose this study was to develop artificial equivalent (ABE) able mimic properties natural concerning abrasion resistance. It two polysaccharides chitosan (ChS) methylcellulose (MC). Polymethylmethacrylate (PMMA) cylinders ( n = 80 ) were manufactured coated with ABE varying concentration ratios ChS MC. Eight test series id="M2"> 8 each) different mixing ChS/MC tested their resistance brushing toothbrush simulator. For ABE, total 2.0 g added 100 ml 2% acetic acid: 0.3–1.0 1.0–1.7 MC, respectively. Furthermore, control id="M3"> only or MC performed. Coated specimens subjected increasing number strokes from 5 45 via test. photographed, computerized planimetric method (CPM) used calculate percentage remaining brushed areas PMMA cylinders. decreased ratio mixture. can be adjusted changing
