RADIATION SAFETY GUIDELINES
Objective: The purpose of these guidelines is to assure uniform
compliance with the Current accepted practices in the use of ionizing
radiation. All practice members are involved directly or indirectly in
radiography and all should adhere to these policies as closely as
possible. The primary intent of these guidelines is to keep patient
radiation exposure to a minimum and to eliminate radiation exposure of
staff.
Ordering Films
A. All radiographs should only be prescribed by a licensed
dentist.
B. The patient's medical and dental history should be reviewed
and an oral examination completed before dental radiographs are ordered.
C. Previous radiographs, especially those taken recently, should
be requested from the previous dentist, these should be evaluated before
ordering films which would cover the same area.
D. Only those radiographs that may be expected to yield
significant diagnostic information should be ordered. If there are other
examination techniques that can provide suitable information, they
should be utilized instead of radiographs.
E. The need for dental radiographs should be based on accepted
selection criteria. These selection criteria are intended as a guide to
the dentist in deciding which films to order.
F. The determination of need for and/or the extent of a
radiographic examination must not be based on arbitrarily established
time frames.
G. Radiographs should not be taken on patients who cannot
cooperate due to mental or physical handicaps. An attempt to do so will
usually result in poor quality films and therefore unnecessary exposure
the patient.
H. Radiographs should not be taken for administrative purposes
only.
I. Screening films used to identify occult lesions are not
acceptable.
J. The recommended guidelines do not need to be altered when
ordering films for a pregnant patient.
K. A history of radiation therapy should not influence the
decision to order dental radiographs.
Radiographic Exposure
1. X-ray equipment is located in each surgery, with the processor
located in the utility room.
2. No person other than the patient should be in the area during
x-ray exposure. If assistance is needed to ensure patient cooperation
(such as with a small child or handicapped patient), a family member or
other
Accompanying person may assist in the procedure. Staff must not hold films for patients during exposures.
3. Infection control policies should be strictly followed.
4. Film-holders should be used to position the films. If this is
not possible because of anatomical restrictions, the patient may use
finger pressure to hold the film in place.
5. During each exposure, the operator should stand at least 2
meter’s away and observation and communication with the patient must be
maintained during the exposure.
