HOSA Dental Terminology Practice

Which of the following is true about calculus in dentistry?

1. It forms naturally in all patients

2. It is completely harmless

3. It is hardened plaque from mineral accumulation

4. It can be treated with regular brushing

The correct answer is: It is hardened plaque from mineral accumulation

The statement that calculus is hardened plaque from mineral accumulation is accurate and highlights an important aspect of dental health. Calculus, also known as tartar, forms when plaque, a soft film of bacteria that develops on teeth, is not removed and subsequently undergoes a mineralization process, typically due to saliva. Over time, the minerals in saliva deposit into the plaque, hardening it into calculus, which can then adhere strongly to the surfaces of the teeth and even under the gumline. This understanding is crucial in dental hygiene and preventive care. While regular brushing can help remove plaque, once it has calcified into calculus, it cannot be effectively cleaned with toothbrushes or dental floss. Professional dental cleanings are necessary to remove calculus. This condition also underscores the significance of regular dental check-ups, as calculus can contribute to gum disease and other dental issues if not addressed.
