Radiographic TechniqueCâu 34 / 100
A finished radiograph has a clear, unexposed curved area along one border. What is this error called and what causes it?
a.Reticulation, caused by a sudden temperature change in processing
b.Fog, caused by an old developer solution
c.Double exposure, caused by exposing the same receptor twice
d.Cone cut, caused by misalignment of the position-indicating device with the receptor
Giải thích
A cone cut is the clear, unexposed area that appears when the beam does not fully cover the receptor because the PID was not properly aligned. Reticulation shows a cracked emulsion pattern from abrupt temperature shifts. Fog produces overall grayness and reduced contrast, and a double exposure shows two superimposed images rather than a blank border.

- Which description matches the paralleling technique for intraoral radiography?
- A processed periapical image shows teeth that appear stretched and longer than they actually are. What caused this error?
- A maxillary premolar image shows teeth that look squat and shorter than normal, with crowns and roots compressed. The most likely cause is:
- On a set of bitewings, the proximal contacts between the premolars are superimposed and cannot be read for caries. What should be corrected on the retake?
