Which statement regarding dental hygiene practices in Oklahoma is accurate?

The statement that Oklahoma has its own specific laws and regulations is accurate because each state in the U.S. creates its own legal framework governing the practice of dental hygiene and other related professions. This includes defining the scope of practice, educational requirements, licensing, and continuing education mandates specific to the state. In Oklahoma, the rules set forth by the state board of dentistry are crucial for ensuring that dental hygienists operate within the law and adhere to the specific guidelines and standards established for practice in the state. This localized approach means that practices and requirements can significantly differ from one state to another, emphasizing the importance of understanding and following Oklahoma's unique regulations.

Regarding the other statements, not all states maintain the same regulations for dental assistants, hence the first statement is inaccurate. The requirement of permits for dental hygienists can vary, and in Oklahoma, hygienists do need to be licensed to practice, contradicting the third statement. Lastly, while expanded functions may often be associated with dentists, certain specific expanded duties can be delegated to dental hygienists depending on state regulations, making the fourth statement misleading.
