Which of the following functions is included in the practice of dental hygiene?

The practice of dental hygiene encompasses a variety of functions, primarily aimed at the prevention and maintenance of oral health. The correct answer focuses on the assessment and implementation of dental care, which are core responsibilities of a dental hygienist.

Dental hygienists perform assessments to evaluate the patient's oral health status, including conducting examinations, taking medical histories, and assessing gum disease and dental issues. Following this assessment, they implement dental care plans, which can include preventive procedures such as cleanings and fluoride treatments, as well as providing patient education about oral hygiene practices.

On the other hand, comprehensive treatment planning involves the broader scope of patient care that typically requires the oversight of a dentist. Placing and removing restorations and administering general anesthesia are procedures that fall within the scope of dental practice for dentists rather than hygienists. Thus, the focus of the practice of dental hygiene is specifically aligned with the assessment and implementation of care, making this the appropriate choice.
