How many hygienists serve on the Iowa Dental Board?

The correct answer indicates that there are two hygienists serving on the Iowa Dental Board. The composition of the Dental Board is designed to ensure that there is representation from various professionals in the dental field, including hygienists. Having two hygienists allows for insights and perspectives that are specific to dental hygiene practice, which is critical for making informed decisions regarding regulations, licensure, and policies that impact dental hygienists in Iowa.

This representation also aligns with the board's goal of promoting effective regulation that considers the different roles within the dental profession. The inclusion of hygienists helps to ensure that the board understands the unique challenges and contributions of dental hygiene in oral health care.

In the context of the other options, having one, three, or four hygienists would not be consistent with the current board structure as established by state regulations. The law specifies the number and types of members required to maintain a balanced and effective board, which is crucial for serving the interests of both dental professionals and the public effectively.
