Final answer:
The statement that dental assistants don't need to be registered if they aren't taking radiographs is false. Dental assistants may still be required to register or meet certain qualifications depending on their state's regulations.
Step-by-step explanation:
The statement that dental assistants don't have to be registered if they're not taking radiographs is False. Registration and certification requirements for dental assistants vary by state. However, most states require dental assistants who perform specialized duties such as taking radiographs to be registered or licensed. Even if a dental assistant is not performing these specific tasks, other general state regulations may still require them to be registered, licensed, or to have met certain educational qualifications. It is essential for anyone considering a career as a dental assistant to check with their state's dental board for specific requirements.
