A Dental X-Ray Machine Operator may perform radiologic procedures when the supervising dentist is not physically present at the location where the radiologic procedures are performed if the supervising dentist examined the patient not more than one year prior to the date the Dental X-Ray Machine Operator performs the radiologic procedures and the supervising dentist has ordered the radiologic procedures.
