What activities fall under the practice of dental hygiene?

The practice of dental hygiene encompasses a variety of activities aimed at promoting oral health and preventing dental disease. The correct choice highlights two key functions of a dental hygienist: performing complete oral prophylaxis and the application of preventive agents.

Complete oral prophylaxis involves the thorough cleaning of teeth, which includes scaling to remove plaque, tartar, and other deposits, polishing teeth, and providing comprehensive patient education on maintaining oral hygiene. This is essential in preventing periodontal disease and cavities.

Additionally, the application of preventive agents such as fluoride treatments and sealants is a crucial part of a dental hygienist's role. These preventive measures help to strengthen teeth, enhance their health, and decrease the likelihood of decay, thereby reinforcing the hygienist's focus on prevention and education.

Overall, dental hygiene is fundamentally about preventive care, and these specific activities directly align with the objectives of a dental hygienist's practice within the dental healthcare framework.
