Wild Card
100
The periodontal structure that normally appears as a thin, radiolucent line of uniform thickness around the root
Periodontal ligament space
100
TRUE OR FALSE: Vertical boneless appears in an uneven direction
TRUE
100
This is the IMAGE OF CHOICE for evaluating Periodontal Disease
Periapical Image
100
Defective restorations can act as local contributing factors for periodontal disease because they are
Severe plaque traps and cause localized bone loss
200
The primary feature used to identify periodontal disease
Changes in the alveolar crest
200
Early stages of periodontal disease typically manifest at the alveolar crest as 
Fuzziness and loss of sharpness of the lamina dura
200
Horizontal bone loss is identified when bone loss occurs
Parallel to adjacent CEJs
200
TRUE OR FALSE:
Dental images provide information about supporting bone that cannot be obtained clinically
TRUE
300
The alveolar crest is normally located
1.5 to 2 mm apical to the CEJ
300
Bone loss extending to the mid third of a tooth with furcation involvement is what stage of periodontitis
Stage III
300
A radiographic finding is MOST suggestive of furcation involvement
Radiolucency in the furcation area
300
Distributed evenly throughout dental arches with less than 30% of the sites involved
Generalized bone loss
400
The alveolar crest in the anterior region is best described as
Pointed, sharp, very radiopaque
400
ADA Case Type associated with no radiographic bone loss
Type I
400
Pointed, radiopaque projections or spikes on proximal surfaces
Dental calculus
400
A Flat, smooth, and parallel line joining adjacent CEJs
A healthy posterior alveolar crest
