ABSTRACT

Biofilms, such as dental plaque, are aggregates of microorganisms attached to a surface. Thus, visualization of biofilms together with their attached substrata is important in order to understand details of the interaction between them. However, so far there is limited availability of such techniques. Here, non-invasive visualization of biofilm formation with its attached substratum by applying the previously reported technique of continuous-optimizing confocal reflection microscopy (COCRM) is reported. The process of development of oral biofilm together with its substratum was sequentially visualized with COCRM. This study describes a convenient method for visualizing biofilm and its attached surface.
