Perio chap 20: Radiographic Analysis of the Periodontium

An example of a radiolucent area on a radiograph is the:

The structure that forms a smooth, intact surface between adjacent teeth with only the width of the periodontal ligament space separating it from the adjacent root surface is called the:

If an adjacent tooth is tilted or erupted to a different height, the crest of the interproximal bone will have a ______ contour.

The continuous white line around the tooth root as seen on radiographs is referred to as the:

Which of the following techniques creates the most anatomically accurate image when exposing radiographs?

Radiographs usually show more interradicular bone between roots of the teeth than what is actually present. Facial and lingual bones can be superimposed over a furcation.

Which of the following statements is true about viewing periodontal pockets on radiographs?

All of the following statements are true about viewing bone loss on radiographs, except: A. By the time bone loss is detectable on radiographs, it has usually progressed past the early stage. B. Radiographs do not always reveal the presence of alveolar bone loss in furcation areas. C. Facial and lingual bone height is difficult to evaluate because teeth are superimposed on bone. D. A radiograph can accurately display the shape and depth of bone deformities.

Radiographs can reveal all of the following periodontal conditions, except:

Radiographs reveal the bone remaining rather than the amount of bone lost. The amount of bone loss can be roughly estimated on a radiograph as the difference between the level of the remaining bone and normal bone height.
