Which component of dental plaque is primarily responsible for its adherence to teeth?

The pellicle layer is a thin film of proteins that forms on the surface of the teeth shortly after cleaning. This layer is primarily composed of salivary proteins and serves as a substrate for the adhesion of bacteria, which is essential for the development of dental plaque. When bacteria in the mouth come into contact with the pellicle, they can easily adhere to it, leading to the colonization and eventual formation of plaque.

This adherence is crucial, as the pellicle provides a stable platform that allows microbial communities to thrive. As plaque accumulates, it can lead to various dental issues, such as caries and periodontal disease. Understanding the role of the pellicle layer highlights its importance in oral health and disease prevention.

Other components mentioned, like salivary proteins and calcium phosphate, play significant roles in oral health and the overall function of plaque but are not the primary agents responsible for the adherence of plaque to teeth. Salivary proteins contribute to the pellicle formation, while calcium phosphate is involved in the remineralization of tooth enamel rather than adhesion of plaque itself.
