What does prophylaxis involve?

  1. Placement of dental crowns

  2. Removal of plaque, calculus, and stains

  3. Filling dental cavities

  4. Conducting root canal therapy

The correct answer is: Removal of plaque, calculus, and stains

Prophylaxis in dentistry primarily involves the removal of plaque, calculus (tartar), and stains from the teeth to prevent dental issues such as cavities and gum disease. This procedure is typically performed during routine dental cleanings and is essential for maintaining oral health. By reducing the buildup of these deposits, prophylaxis helps to minimize the risk of periodontal disease and decay, which can lead to more severe complications if left untreated. This preventative approach is an integral part of dentistry, as it promotes better oral hygiene and overall health, making it crucial for patients to undergo regular prophylactic treatments as recommended by dental professionals. The other options pertain to specific restorative or therapeutic procedures, rather than preventative care.
