The Consumer-Patient Radiation Health and Safety Act of 1981 [PL 97-35] requires dental personnel be trained and certified in dental radiology. The intent of radiology certification is to eliminate unnecessary radiation exposure to the patient, operator, and other staff while assuring quality, diagnostic radiographs. The certification process involves successfully passing a written examination, and demonstrating clinical competency while adhering to accepted radiological practices.

Learning Objectives:

After completing this course, dental auxiliaries will be prepared to take the written exam, and demonstrate competency in the following areas:

Infection Control

  •    Place barriers or disinfect operatory and X-ray equipment.
  •    Wear appropriate PPE.
  •    Select appropriate X-ray film, and assemble the XCP.
  •    Disinfect protective devices [apron and thyroid collar].
  •    Limit contamination when processing X-rays.

    Patient Protection
  •    Place protective device [apron/thyroid collar] on each patient during all exposures.
  •    Store protective devices to reduce creasing and damage.
  •    Stabilize the PID or cone and positioned it in close proximity to the XCP when the exposure is made.
  •    Patient never holds film or stabilizes PID [cone].

    Operator Protection
  •    Stand at least six feet from the patient and not in the path of the primary beam or behind protective barrier during exposure.
  •    Allow only necessary persons in radiographic area during exposures.
  •    Give a warning prior to pushing the X-ray activator button.
  •    Staff never holds film or stabilizes PID [cone].
  •    Wear dosimeter [film badge].

    Take, Process, Mount Diagnostic Radiographs
  •    Film placement is appropriate for the area of the mouth under study.
  •    Density and contrast of radiographs are such that anatomical hard and soft tissue landmarks can be differentiated.
  •    Radiographic image size is not distorted in the area of the mouth under study.
  •    Radiographs disclose no overlapping image in the area of mouth under study, except where tooth alignment does not permit open contacts.
  •    Radiographs disclose no cone-cutting.
  •    Bitewing radiographs include the distal surface of the erupted canines and distal surface of the most posterior erupted teeth.
  •    Radiographs show no processing errors.
  •    Dental radiographs are mounted and contained in the patient’s dental record, and include the following:
  •    Patient’s name and chart number
  •    Date radiographs taken
  •    Initials of the dentist who ordered the films
  •    Initials of dental assistant who took the films
