accuracy

while gloved, carefully remove the sealed barrier, and place the PSP into a

black transfer box

screens should be checked monthly with a commercially available:

cleaner

once films are removed from the mouth, they are considered:

contaminated and should only be handled with gloved hands

PSPs are a major source of _______ during image procedures

cross contamination

you must replenish the processing solutions _____ and change them every _____ as recommended by the manufacturer

daily; 3-4 weeks

dental images are the property of the

dentist

who's responsibility is it to discuss the need for dental imaging

dentist

can be checked by using a reference image and stepwedge image

developer strenth

intensifying screens inside the extra-oral cassette should be periodically checked for:

dirt and scratches

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

duplicate copy with patient or emailed digital copy

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
