What is the primary authority of the Iowa Dental Hygiene Committee?

The Iowa Dental Hygiene Committee has the primary responsibility for overseeing all matters regarding dental hygiene practice. This authority includes establishing the standards of practice, ensuring compliance with regulations, and addressing issues that pertain specifically to the field of dental hygiene. By focusing on the nuances of this specific profession, the Committee plays a crucial role in maintaining the quality and integrity of dental hygiene services provided to the public.

The role of licensing dental professionals, although critical, is part of a broader scope that typically falls under state dental boards or commissions as a whole rather than just the dental hygiene sector. Public health counseling and governing dental assisting may also be important functions within the broader dental care framework but do not directly reflect the main duties and responsibilities assigned to the Iowa Dental Hygiene Committee. Therefore, option B accurately captures the primary focus of the Committee's authority.
