Retrieval of biofilms from the oral cavity.

With the use of the removable stents or bonded enamel piece models with or without a continuous bacterial layer, many in vitro or in vivo studies can be initiated. For example, studies on salivary pellicle formation, surface characteristics of biomaterials as they affect plaque development, antiplaque agents, the dynamics of adhesion of bacteria, interspecies adhesion of bacteria, the colonization of bacteria, the dynamics of bacterial growth in vivo, and the succession of growth in older supragingival plaques can be carried out.
