True or False: A hygienist can supervise others under a public health supervision agreement.

In Iowa, dental hygienists have specific regulations governing their practice, including supervision requirements. Under a public health supervision agreement, hygienists can provide care without direct supervision from a dentist. However, this does not extend to supervising others; the role of supervising coworkers or assistants typically falls within the purview of the dentist. Therefore, under Iowa law, a hygienist cannot supervise others in this context, making the statement false.

This is an important distinction within the practice of dental hygiene, as it highlights the limits of a hygienist's authority and reinforces the necessity for dentist oversight in supervising staff. Understanding these regulations is essential for adhering to legal standards in the state, ensuring safe and effective patient care while following the proper chain of command in a healthcare setting.
