Dental Radiography: Occlusal and Localization Techniques

Practice flashcards based on the lecture notes covering Dental Radiography, focusing on occlusal and localization techniques.

What is the purpose of occlusal examination?

To visualize large areas of the maxilla or mandible.

What principle is used to stabilize the receptor during the occlusal technique?

The receptor is stabilized when the patient bites on the surface of the receptor.

What are the recommended vertical angulations for maxillary occlusal projections?

Topographic: +65°, Lateral: +60°, Pediatric: +60°.

What does the buccal object rule help to determine?

The position of a tooth or object in the jaws based on the movement direction of the PID (position-indicating device).

What vertical angulation is recommended for mandibular cross-sectional occlusal projections?

90°.

What are the two localization techniques mentioned in the lecture?

Buccal object rule and right-angle technique.

What must be explained to the patient during preparation for taking occlusal images?

The imaging procedure.

What is the recommended vertical angulation for mandibular topographic occlusal projections?

-55°.

What are the three dimensions used in the right-angle technique to locate an object?

Superior-inferior, anterior-posterior, and buccolingual dimensions.

What does the pneumonic SLOB stand for in the buccal object rule?

Same, Lingual, Opposite, Buccal.

What should be done if the impacted tooth appears to have moved in the same direction as the PID shift?

The tooth is positioned to the lingual.

What type of projection is used to visualize the palate and anterior teeth of the maxilla?

Maxillary occlusal topographic projection.

What is unique about the pediatric projection in maxillary occlusal imaging?

It is recommended for use in children 5 years old or younger.

How do you prepare equipment for the occlusal imaging technique?

Set exposure control factors according to the receptor manufacturer's recommendations.

What is the primary use of localization techniques in dental radiography?

To locate foreign bodies, impacted teeth, or unerupted teeth.

What are some typical uses of the occlusal examination?

To visualize large areas when periapical imaging is difficult or when the area of interest exceeds the dimensions of a periapical receptor.
