What is the benefit of using dental PSP over traditional film-based radiography?

• A. Higher radiation exposure
• B. Slower image processing
• C. Digital storage and easy retrieval
• D. Limited image manipulation

In the process of reading a dental PSP, what device is used to convert the stored energy into a visible image?

• A. X-ray machine
• B. Laser scanner
• C. Dental chair
• D. Autoclave

What is the function of the protective barrier on a dental PSP?

• A. Enhance X-ray absorption
• B. Prevent scratching and contamination
• C. Increase radiation exposure
• D. Improve image resolution

How is a dental PSP erased after an image has been captured and processed?

• A. Exposure to white light
• B. Soaking in water
• C. Using disinfectant solution
