Xray

1. The blurred or fuzzy area around an image (the "shadow").
4. This controls the quantity of X-rays produced.
5. The overall blackness or darkness of a radiograph.
7. The chemical solution that "clears" the unexposed silver halide crystals.
9. The lead disc that limits the size and shape of the X-ray beam.
11. A badge worn by staff to measure their radiation exposure over time.
12. The tip of the tooth root shown on a periapical radiograph.
13. The coating on the film that is sensitive to radiation.
14. The difference between the shades of black, white, and gray on an image.
15. An error where the PID is not centered, leaving a clear crescent shape.
17. This controls the penetrating power (quality) of the beam.
18. An error where teeth look too long due to low vertical angulation.

2. Structures that allow radiation to pass through and appear dark (like pulp).
3. Structures that block radiation and appear white (like metal crowns).
6. The physical medium used in manual processing (though digital is now common).
7. An error where teeth look too short due to high vertical angulation.
8. An extraoral X-ray showing a wide view of the entire upper and lower jaw.
10. The specific X-ray used to detect interproximal decay.
16. The radiation safety principle
