What is the discipline of dental hygiene?

Question

Quizplus · Accepted Answer

The study of teeth and their supporting structures. This answer is wrong because the discipline of dental hygiene covers much more information than the study of teeth and supporting structures. Dental hygiene focuses on the preventive measures that the teeth and supporting structures must receive, in addition to other oral healthcare steps that must be taken to promote one's health.
Brushing and flossing one's teeth and rinsing with an antimicrobial mouth rinse twice a day, morning and night. This answer is wrong because this statement describes only one procedure within the discipline of dental hygiene. Dental hygiene is a much larger and general field of study than this simple preventive action.
The study of preventive oral healthcare including the management of behavior to prevent oral disease and promote health. This answer is correct because this is the direct definition of dental hygiene. The definition can be broken down into smaller, specified divisions to further develop the discipline of dental hygiene.
The study of those procedures that dental hygienists provide to clients. This answer is wrong because dental hygienists play many interrelated roles, such as clinician, educator, administrator or manager, advocate, and researcher. Although each of these roles is created to assist in dental hygiene, the discipline is not centered on the actions and procedures of the dental hygienist.
