Inspection and maintenance
Inspection and maintenance work must be performed at
regular intervals to protect the safety and health of
patients, users and third parties.
14.1
Annual inspection performed by the operator or other authorized personnel
As the operator, you should ensure the safety and relia-
bility of your system by performing maintenance on it at
regular intervals (at least once annually) or having this
work performed by your dental dealership.
The information in the document
’Inspection and main-
tenance’
supplied will be of help to you here.
14.2
Maintenance performed by the service technician
In addition to the scheduled annual inspection by the
user or persons contracted to perform this, a mainte-
nance inspection must be performed after 4, 7 10 and
then every two years.
The information in the document
’Inspection and main-
tenance’
supplied will be of help to the service techni-
cian here.
14.3
Checking image quality
At regular intervals, however at least once a year, the
user must evaluate the image quality.
With the use of digital image receptors, the increase in
image post-processing effort making use of the bright-
ness or contrast control (e.g. for SIDEXIS) can be taken
as an evaluation criterion.
For X-rays requiring developing of films, an increase in
the exposure time serves as the evaluation criterion.
If these evaluation criteria are fulfilled independently of
the patient anatomy and of possible sources of error,
such as developing of film or patient positioning, contact
a service technician immediately in order to eliminate
possible unit faults.
In addition it is necessary to observe country-specific
requirements.
Furthermore, we would like to call your attention to the
brochures of film manufacturers and also to our Quality
Image Service. For this, please contact your dental
dealer or the manufacturer directly.
