Which of the following actions is NOT part of the dental hygienist's responsibilities?

The action of cutting soft tissues is not within the scope of a dental hygienist's responsibilities. Dental hygienists are trained and licensed professionals who provide preventive and therapeutic oral care but do not engage in surgical procedures, which include cutting soft tissues. Such tasks are reserved for dentists and oral surgeons who have the specific training and legal authority to perform surgeries and more invasive procedures.

The responsibilities of dental hygienists typically include implementing oral health counseling to educate patients on maintaining proper oral hygiene, performing screenings to assess the health of teeth and gums, and assisting in planning dental care by collaborating with the dentist on treatment plans. These responsibilities are essential in promoting overall oral health and preventing dental diseases, reflecting the preventive nature of dental hygiene practice.
