Which statement is true regarding dental hygiene practice in Arizona?

The statement about dental hygienists facing strict examination requirements for licensure is true because in Arizona, candidates must complete an approved dental hygiene program and pass both a written and a clinical examination to become licensed. This rigorous process ensures that only qualified individuals are allowed to practice dental hygiene, reflecting the importance of maintaining high standards in patient care and safety.

In Arizona, continuing education and the renewal of licenses are also critical aspects of maintaining professional qualifications, which adds another layer to the strict licensure and examination requirements. This ensures that dental hygienists stay updated with the latest practices and protocols in the field.

The other statements about supervision, independent performance, and license renewal do not accurately reflect the regulatory framework governing dental hygiene practice in Arizona, where specific guidelines on supervision and independence exist, along with mandatory license renewal practices.
