What is calculus in dental terminology?

  1. A type of dental procedure

  2. Hardened plaque caused by mineral accumulation

  3. The area where teeth meet

  4. A type of dental film

The correct answer is: Hardened plaque caused by mineral accumulation

Calculus in dental terminology refers specifically to hardened plaque that forms on the teeth due to the accumulation of minerals, primarily calcium and phosphate, from saliva. When plaque is not removed through regular brushing and flossing, it can mineralize and turn into calculus, also known as tartar. This hardened deposit can contribute to gum disease and decay if not properly managed, as it provides a rough surface for further plaque accumulation and can irritate the gums. Understanding calculus as a hardened form of plaque helps highlight the importance of regular dental hygiene practices, including professional cleanings, to prevent its formation and subsequent oral health issues. This definition distinguishes it clearly from the other choices, which relate to different aspects of dental health or procedures but do not accurately describe what calculus is in the context of dental terminology.
