the process of informing the patient about the nature and purpose dental imaging
disclosure
dental records must contain
documentation of the dental images taken
copies are sent

after removing each exposed film or PSP from the patient's mouth, wipe saliva from...
film packet with a dry 2x2 gauze or paper towel
in order for a film to be properly processed, it should be left in fixer solution at what strength for how long?
full strength for 2 minutes
most states have laws that require _____ of dental x-ray equipment on a regular basis
inspections
the most critical in film processing quality control is
maintaining the freshness of the processing solutions
dental radiography presents unique infection control problems because of the
potential for cross-contamination of equipment and environmental surfaces with blood and saliva
the simplest method for ensuring that each box film is fresh is to:
process one film from each box with fresh chemicals
callibration of dental x-ray equipment should be performed by a___
qualified technician
a way of ensuring that everything possible is being done to produce high quality diagnostic images
quality assurance
processing solutions are the most critical component in the
quality control of film processing
The consumer-patient radiation health and safety act is a federal law that
requires all persons who use xrays to take dental images to be properly trained and certified
PSPs are reusable and must be placed in a
sealed barrier packet before exposure
sterilized positioning instruments
should remain packaged until the patient is seated and can view the package being opened
regulations regarding certification for dental assistants vary from
state to state
instruments that are placed in the patient's mouth are semi-critical items that should be
sterilized before reuse
who can be held legally responsible for the dental assistant's actions
the dentist and dental assistant
if the process film appears clean with a slight blue tint:
the film is fresh and has been stored properly
after performing the film-screen contact test areas of good film-screen contact will be:
uniform
the safelight in the darkroom can be tested by
using the coin test
patients may request a copy of their images and this request should be
written and signed by the patients
quality control for the darkroom should include:
- checking for light leaks every six months - safelight testing - equipment testing
a record keeping log for processing solution should include
- date of solution replacement - date tanks were cleaned - date of solution replenishment
according to CDC guidelines in dental healthcare setting, digital radiography sensors should use
FDA-cleared barriers
quality administrative procedures deals with the management of the
QA program in the dental office
Quality administrative procedures include:
- in-service training should be provided to ensure that each individual is trained to perform assigned duties - maintains a written description of the quality insurance plan available to all staff members - a record keeping log of all quality control tests maintains records of control tests
barriers need to be used because
- the operator places the image receptor (film, psp, sensor) into the mouth - moves the exposure controls outside the operatory - returns to remove the image receptor or reposition in the mouth
how we do quality assurance
1. administration procedures 2. control tests
if the patient refuses dental x-rays what must be done:
1. document the refusal 2. explain the importance of dental imaging
the documentation of dental images taken must include:
1. number 2. type 3. quality
what must be disclosed to the patient before obtaining informed consent?
1. risks and benefits of the images 2. person who will be exposing 3. consequences of not having images
original film/images are
NOT sent to patient
