† Increasingly, primary care medical providers are delivering the identified preventive oral health services during well-child exams. Physicians may perform all listed procedures under the scope of practice of their license, but rarely perform more than the functions shown. Physician assistants and advanced practice nurses have more limited scopes of practice than physicians, but when delivering oral health services, they perform the same procedures as physicians.
