Suggested Regulatory ApproachAdvise all CBCT registrants that FDA classifies as CT (Once we officially confirm)Advise registrants that only the Dentist, Physician, Dental Hygienist(?) or Diagnostic Technologist can operate CBCTProvide registrants 90 days to develop and 180 days to implement alternative QA program as permitted by N.J.A.C. 7:28-22.3(g).
