Intraoral radiographic techniques 2

In the paralleling technique, a long cone is used

• True

• False

How can we compensate for the increased distance between the film & the tooth in the paralleling technique?

• by using a short cone

• by using a long cone

• by moving the tooth closer to the film

• by moving the tooth closer to the x-ray beam

In the paralleling technique, vertical and horizontal angulations must be adjusted

• True

• False

The film is oriented ... when taking a periapical x-ray for the anterior teeth using the paralleling technique

• vertically

• horizontally

• obliquely

The film is oriented ... when taking a periapical x-ray for the posterior teeth using the paralleling technique

• vertically

• horizontally

• obliquely

In the paralleling technique, the zygomatic bone is superimposed on the upper molar teeth

• True

• False

In the paralleling technique, it is possible to make reproducible views

• True

• False

Bitewing x-ray is used to see all the following except:

• interproximal teeth surfaces

• crestal bone

• teeth apices

• crowns

In bitewing x-ray, the position of the dot should be ...

• apical

• occlusal

• interproximal

• it doesn't matter

When using tabs in bitewing x-ray, the vertical angulation should be:

• +10 degrees

• +20 degrees

• Zero degrees

• +55 degrees
