Question

radiopaque artifiacts or radiolucent scratch marks on the image indicate which of the following?

Arindam · Answer

Radiopaque artifacts or radiolucent scratch marks on a dental image indicate handling or processing errors that affect the quality of the radiograph.

Possible Causes:

Film Radiography (Traditional X-rays):
- Scratches on the film emulsion → Appear radiolucent (dark lines or marks).
- Static electricity from improper handling → Can create black tree-like patterns.
- Contaminants (e.g., fingerprints, saliva, or fixer spills) → Appear as radiopaque (white) marks.
Digital Radiography (Sensors & PSP Plates):
- Scratched or damaged PSP plate → Produces radiolucent lines.
- Dust or debris on sensor/plate → Can create radiopaque artifacts.
- Bite marks or excessive pressure on sensor → Can lead to permanent artifacts.

Prevention & Solutions:

✅ Handle film/sensors carefully to avoid scratches and contamination.
✅ Keep PSP plates clean and store them properly.
✅ Use gloves to prevent fingerprints or smudges.
✅ Check the processing equipment to ensure no mechanical damage occurs.
