Final answer:
Home study courses are generally not a requirement for obtaining orthodontic and sedation permits. The typical requirements include work experience, board approved courses, and passing relevant examinations.
Step-by-step explanation:
The requirement that is not typically needed for obtaining orthodontic and sedation permits is: home study courses. Generally, to receive these permits, a dental professional will need to amass a certain amount of work experience in the field, complete board approved courses that offer hands-on training, and pass the necessary examination requirements. Home study courses, while potentially beneficial for additional knowledge acquisition, are not usually a formal requirement for obtaining these specialized permits. As regulations may vary by region, it's important for dental professionals to check the specific requirements of their local dental board or regulatory body.
