Demineralization of human enamel covered with LCFV containing different zwitterionic materials after exposure to BHI culture medium supplemented with 2% sucrose and S. mutans inoculum. (A) Representative polarized light microscopy images before and 14 days after exposure to S. mutans (scale bar = 500 µm, D: dentin, E: enamel). Blue arrowheads indicate LCFV covering enamel surfaces before exposure to S. mutans. Red arrowheads indicate the progression of dental caries 14 days after exposure to S. mutans. (B) Depth of demineralization 14 days after exposure to S. mutans. Different letters above the bars indicate significant differences (*P < 0.05).
