What is the primary component of plaque?

• A. Water
• B. Inorganic substances
• C. Bacteria
• D. Fats

Answer: (C)

The primary component of plaque is bacteria. Dental plaque is a sticky, colorless film of bacteria that forms on the teeth and can lead to dental caries and gum disease if not properly managed. The bacteria in plaque adhere to the tooth surface and produce acids as they metabolize sugars from food. This acidic environment can demineralize tooth enamel, leading to cavities. The presence of bacteria is crucial, as they are responsible for the changes that occur in the plaque over time, including its development into calculus if not removed. While water, inorganic substances, and fats may be present in smaller amounts, they do not constitute the primary structure of plaque. Water acts as a medium for the bacterial community, inorganic substances can contribute to calculus formation, and fats are not significant constituents of plaque. The overwhelming presence of bacteria is what defines plaque and underscores its potential impact on oral health.
