Study Notes
Dental Radiography Quality Assurance
- The American Dental Association (ADA) recommends annual tests for dental x-ray machines.
Quality Assurance Plan
- A quality assurance plan in a dental office ensures that dental x-ray equipment is functioning properly and producing high-quality images.
Dental X-ray Film Storage
- To determine if a dental x-ray film is fresh and properly stored, check the expiration date and storage conditions.
Radiolucent Lesion Appearance
- A unilocular radiolucent lesion exhibits one compartment.
- A multilocular radiolucent lesion exhibits multiple compartments that resemble soap bubbles.
- A radiolucent lesion with ill-defined or irregular margins is described as "hazy" or "ill-defined".
Tooth Apex
- The area around the apex of a tooth is called the periapical area.
Developer Solution Strength Test
- A sensitometer is used to test the strength of the developer solution.
Daily Radiograph Density
- If the density seen on the daily radiograph differs from that on the standard radiograph by more than two steps on the step wedge, adjust the x-ray machine or processing technique.
Clearing Test
- The clearing test monitors the effectiveness of the fixer solution.
- If the film does not completely clear in 3 to 4 minutes during the clearing test, adjust the fixer solution or processing technique.
Screen-film Contact Test
- The correct procedure for the Screen-film Contact Test involves placing a wire mesh over the film and exposing it to x-rays; the resulting image should show a uniform pattern.
Radiopaque Lesion Appearance
- A radiopaque lesion that appears as multiple radiopacities that overlap or flow together is described as "scalloped" or "wavy".
- A radiopaque lesion that exhibits both radiopaque and radiolucent components is described as "mixed".
- A radiopaque lesion that appears as a well-defined, radiopaque area located in soft tissue is described as "radiopaque".
- A radiopaque lesion that is a well-defined, localized radiopaque lesion on a dental image is described as "periapical".
Light Leak Test
- The correct procedure for the Light Leak Test involves placing a film in a light-tight box and exposing it to a light source; the resulting image should show no evidence of light leaks.
Automatic Processor Test
- If the unexposed film does not appear clear and dry in the Automatic Processor Test, adjust the processor or processing technique.
Dental Radiographer Role
- The dental radiographer's role in image interpretation is to identify abnormalities and provide a preliminary interpretation, but not to make a diagnosis.
- The dental radiographer is not responsible for making a diagnosis, but rather for providing a preliminary interpretation.
- Interpretation involves identifying abnormalities, while diagnosis involves determining the cause of the abnormality.
- Dental images should ideally be reviewed and interpreted immediately after exposure.
