How many licensed dental hygienists are part of the Arizona State Board of Dental Examiners?

The correct answer is that there are two licensed dental hygienists on the Arizona State Board of Dental Examiners. This composition is essential because it ensures that the interests and expertise of dental hygienists are represented in the decision-making processes of the Board, which oversees the regulation of dental practice in Arizona.

Having two licensed dental hygienists allows for a diversity of perspectives, enhancing the Board's ability to address issues specific to the practice of dental hygiene and to advocate for the profession within the wider context of dental health care regulation. This framework aligns with the goals of ensuring patient safety and maintaining high standards of dental hygiene practice in the state.

The other numbers presented in the options do not accurately reflect the established structure of the Board, as they do not meet the requirement for proper representation of licensed professionals within the dental hygiene field.
