Registered Dental Hygienist in Alternative Practice (RDHAP) Law and Ethics Practice Exam

Which procedure is included in the definition of "Oral prophylaxis"?

1. Extraction of teeth

2. Making impressions for crowns

3. Scaling and removal of calculus

4. Placement of dental fillings

The correct answer is: Scaling and removal of calculus

Oral prophylaxis refers specifically to the procedures aimed at preventing oral diseases and maintaining oral health, typically carried out in a dental setting. The correct choice, which involves scaling and removal of calculus, is a fundamental part of oral hygiene practices designed to prevent periodontal disease and maintain the health of the gums and teeth. This procedure helps in removing plaque and tartar that can build up on teeth, ensuring that the oral environment remains healthy. The other options involve procedures that do not fall under the remit of oral prophylaxis. For instance, tooth extraction is a surgical procedure aimed at removing a tooth, which is more about treatment rather than prevention. Making impressions for crowns typically involves preparing the teeth for restoration work and is part of restorative dentistry rather than prophylaxis. The placement of dental fillings is also a restorative procedure addressing existing dental issues, instead of preventing future problems. Therefore, the act of scaling and removing calculus is integral to maintaining oral health, making it the correct answer in the context of oral prophylaxis.
