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.

In vivo Colonization of Salivary Pellicle by Haemophilus, Actinomyces and Streptococcus Species

Eight human subjects with healthy oral conditions were examined to study developing dental plaque. Supragingival plaque, buccal mucosa, tongue dorsum and saliva were sampled prior to the pumicing and

Effect of Neuraminidase on the Adherence to Salivary Pellicle of Streptococcus sanguis and Streptococcus mitis

Neuraminidase-sensitive adherence to experimental salivary pellicles was studied using eight strains of Streptococcus sanguis and five strains of Streptococcus mitis. Approximately 60% of the strains of each species showed significantly lower adherence to neuraminidase-treated versus untreated saliva-coated hydroxyapatite. In addition, the adherence of several of these streptococcal strains to saliva-coated hydroxyapatite and neuraminidase-treated saliva-coated hydroxyapatite was inhibited using galactose and N-acetyl-D-galactosamine. Results from these studies suggested that several salivary receptors mediate adherence of these species.
