The human tooth has a natural protective mechanism. This mechanism may act against bacterial colonization that complements the defensive role of saliva. The hard enamel part of the tooth selectively absorb acidic glycoproteins from saliva and it is referred to as mucins. This results in the formation of a membranous layer known as the acquired enamel pellicle, which confers a net negative charge. Most bacteria possess a net negative charge, thus there will be repulsion between the tooth surface and the bacteria. Dental plaque is formed when the natural protective mechanism fails.

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
