To take radiographs as a dental assistant in Nevada, the dentist must submit a statement containing your name, position, and that you’ve completed a CPR certification every two years while employed, four hours of infection control training, instruction from the dentist on radiographic procedures, and a copy of Nevada statutes and dental regulations. Dental assistants are still trained in-office to take radiographs because it does take some skill and safety precautions to take them correctly. Radiographs do expose the human body to slight amounts of radiation, typically dental assistants will limit their exposure by setting up the radiograph and activating the sensor a few feet away from the patient. In some dental offices, pregnant dental assistants are not to take radiographs. If you do have concerns about taking radiographs regularly, most dental offices will accommodate you, but there really is not much to worry about with the limited exposure.
