What is one of the primary constituents of plaque?

1. Fluoride

2. Saliva

3. Water

4. Calcium

The correct answer is: Saliva

The primary constituent of plaque is saliva. Plaque, which is a sticky film of bacteria that forms on teeth, is greatly influenced by the presence of saliva. Saliva plays a crucial role in oral health as it contains various components, including proteins and enzymes, that contribute to the formation and maintenance of dental plaque. It facilitates the adherence of bacteria to the tooth surface and provides a medium for the accumulation of microorganisms. Saliva also provides minerals like calcium and phosphate, which are important for remineralization, but its primary role is to create an environment where plaque can thrive. The antibacterial properties of saliva help to manage the microbial diversity in the mouth, but when there is an imbalance, plaque can develop more readily. Without saliva, the conditions for plaque formation would be significantly different, making it a vital factor in understanding plaque composition. The other options listed, such as fluoride, water, and calcium, do play roles in dental health, but they do not serve as the primary constituent of plaque itself. Fluoride is known for its protective benefits against cavity formation, while calcium, although important for teeth, is not a major constituent of plaque. Water is essential for many bodily functions, including the production of saliva, but it is not the main component
