| Question | Answer |
|---|---|
| Use of high-speed film will? | Decrease exposure time |
| A routine periapical radiograph of a premolar (bicuspid) should show? | the distal of the canine, the first and second premolars (bicuspids), and most of the first molar |
| The tissue most sensitive to X-radiation is: | Blood |
| Light films will result from? | Under developing and under exposure |
| If a film is exposed on the wrong side, the result will be | A herringbone pattern |
| A black image on a film caused by an inadequate time/temperature cycle is due to: | Over development |
| A technique utilized to expose a radiographic image of a curved layer with a narrow beam of X-rays is known as: | Rotational panoramic radiography |
| The type of film utilized to record, measure, and compare changes in the growth of the bones and the teeth is: | Cephalometrick film |
| Which type of film exposure is most helpful for locating a stone or calculus accumulation in Wharton's duct? | Occlusal film |
| Elongation is caused by | Insufficient vertical angulation |
| Low optical density of the processed film results in a: | Thin image |
| Proper collimation for the film size and target film distance will | decrease the radiation received by the patient |
| Regardless of the target-film distance, incorrect horizontal angulation will cause: | Overlapping of teeth in the x-ray image |
| In the darkroom, a cassette was opened to remove an exposed film. A peice of black paper was discovered on the surface of the intensifying screenk. The paper would mose likely produce? | A white or light artiface |
| Neutrons have? | No charge |
| The mandibular second molars have _________ roots. | Two |
| A solid opaque vertical line appearing on the radiographic panoramic processed film may be caused by: | Releasing the exposure button for a moment |
| The major reason for reduction of exposure time when producing diagnostic radiographs is to protect the patient from: | Primary radiation |
| Foreshortening of the radiographic image is due to __________ angulation. | Too much vertical |
| Foreshortening of the film is due to _________ of the position indicating device. | Too much vertical angulation |
| If film is moved from one bath at a high temperature to another at a lower temperature, the result will be: | Reticulation |
