Formation Of Dental Plaque
Formation development of dental plaque pellicle is the initial organic structure that forms on the surfaces of the teeth and artificial prosthesis.
Formation of dental plaque. When a tooth is brushed with an abrasive agent it is possible to remove all the organic material that has accumulated on the surface and expose the naked apatite crystals. This results from the electrostatic ionic interaction between hydroxyapatite surface which has negatively charged phosphate groups that interacts with opposite charged groups in the salivary macromolecules. The bacteria in plaque feed on.
Although over 500 bacterial species comprise plaque colonization follows a regimented pattern with adhesion of initial colonizers to the enamel salivary pellicle followed by secondary colonization through interbacterial adhesion. The first stage in pellicle formation involves adsorption of salivary proteins to apatite surfaces. Dental plaque is a complex biofilm that accumulates on the hard tissues teeth in the oral cavity.
