Which term refers to the scraping away of material, particularly in a dental context?

  1. Debride

  2. Gingivectomy

  3. Prognathia

  4. Gingivitis

The correct answer is: Debride

The term that refers to the scraping away of material in a dental context is debried. In dentistry, debridement is often used to describe the process of removing decay, plaque, or calculus from the surfaces of the teeth or from within the gums. This procedure is crucial for maintaining oral hygiene, facilitating healing, and preventing further dental issues. In contrast, gingivectomy is a surgical procedure specifically aimed at removing diseased gum tissue to improve the health of the gums, but it does not emphasize the general scraping away of material. Prognathia refers to a condition where the mandible or maxilla is protruded, which does not relate to the removal of material. Lastly, gingivitis is the inflammation of the gums, a condition that also does not involve scraping but rather indicates the presence of plaque and tartar build-up that may require debridement.
