Which of the following terms describes bone loss that occurs in a plane parallel to the cementoenamel junction of adjacent teeth?
a. irregular b. vertical c. horizontal d. periapical |
c. horizontal |
|

Significant bone loss that results in a radiolucency observed in the area between the root of a multirooted teeth is called.
a. localized bone loss b. interdental septa c. local contributing factor d. furcation involvement |

Radiographs may help to locate each of the following local contributing factors EXCEPT one. Which is the EXCEPTION?
a. Calculus b. Poorly contoured crown margin c. deep pocket d. amalgam overhang |
c. deep pocket |
|
|
excessive occlusal force may result in a widening of the periodontal ligament space. Widening of the periodontal ligament space is called furcation involvement.
a. Both statements are true b. Both statements are false c. The first statement is true; the second statement is false d. The first statement is false; the second statement is true |
c. The first statement is true; the second statement is false |
|
|
Dental radiographs are important because they document the location and depth of periodontal pockets. Dental radiographs may serve as a baseline and as a means for evaluating the outcome of periodontal treatment.
a. Both statements are true b. Both statements are false c. The first statement is true; the second statement is false d. The first statement is false; the second statement is true |
d. The first statement is false; the second statement is true. |

|
List the four limitations of dental radiographs in assessing periodontal disease.
a. ______________________________ b. ______________________________ c. ______________________________ d. ______________________________ |
- Radiographs are a 2D image of a 3D object - Changes in soft tissue not imaged - Cannot distinguish treated versus untreated disease. - Actual destruction more advanced clinically |
|
|
Which of the following would be best for imaging a slight, but generalized periodontal status?
a. select periapical radiographs using the bisecting technigue b. select periapical radiographs using the paralleling technique c. posterior horizontal bitewings radiographs. d. posterior and anterior vertical bitewing radiographs
|
d. Posterior and anterior vertical bitewing radiographs |
|
|
Correct horizontal angulation is needed to accurately image interdental bone levels. Altering the horizontal angulation can reveal additional information regarding bone levels.

a. Both statements are true |
