Answer 5

Periodontal ligament space

paralleling technique

Question 10

the __ bite wing image alone should not be used to document moderate to severe perio disease but what can

Answer 10

horizontal bite wing

Vertical bite-wing image

Question 11

___ of bone loss viewed on a dental image is described as horizontal or vertical

Answer 11

Pattern

Question 12

what is also known as angular bone loss

Answer 12

vertical bone loss

Question 13

the ___ of bone loss seen on a dental image can be described as localized or generalized

Answer 13

distribution

Question 14

bone loss occurs evenly throughout the dental arches, with more than 30% of the sites involved

Answer 14

generalized bone loss

Question 15

bone loss that occurs in isolated areas, with less than 30 percent of the sites involved

Answer 15

localized bone loss

Question 16

Answer 16

Severity

Question 17

the severity of bone loss is measured by the ___

Answer 17

CAL

clinical attachent loss

Question 18

1-2mm bone loss

Answer 18

Question 19

3-4mm bone loss

Answer 19

moderate bone loss

Question 20

5mm greater

Answer 20

sever bone loss

Question 21

gingivitis is ADA type

Answer 21

ADA Type 1

Question 22

mild or slight periodontitis is ADA

Answer 22

ADA Type II

Question 23

Moderate periodontitis is ADA

Answer 23

ADA Type III

Question 24

Advanced or sever periodontitis is ADA

Answer 24

ADA Type IV

Question 25

No bone loss is associated with type I disease (gingivitis); therefore, no change in bone is seen on the dental image. The crestal lamina dura is present, and the alveolar crest is approximately 1 to 2 mm apical to the CEJ. Clinically, bleeding on probing may be present. Only the gingival tissues are affected by the inflammatory process in ____; no hard tissue changes are seen.

Answer 25

ADA Case Type I

Question 26

The bone loss associated with ____ is mild crestal changes ( Figures 34-17 to 34-19 ). The lamina dura becomes unclear and fuzzy and no longer appears to be a continuous radiopaque line. Horizontal bone loss is seen more often in type II disease, with the alveolar bone level approximately 3 to 4 mm apical to the CEJ. Clinically, bleeding may occur on probing, and pocket depths resulting from attachment loss as well as localized areas of gingival recession may be evident.

Answer 26

type II disease (mild or slight periodontitis)

Question 27

Horizontal or vertical bone loss may be present in _____; the distribution of the bone loss may be localized or generalized ( Figures 34-20 to 34-23 ). The alveolar bone level is approximately 4 to 6 mm apical to the CEJs of adjacent teeth. Bleeding upon probing may be present. Furcation involvement, or the extension of periodontal disease between the roots of multirooted teeth, may also be seen in _____. When bone in the furcation area is destroyed, a radiolucent area is evident on the dental image ( Figure 34-24 ). Clinically, pocket depths and attachment loss up to 6 mm are evident. Recession, furcation involvement areas, and slight mobility may also be present.

Answer 27

type III disease

Question 28

The bone loss associated with ______indicates further progression of the disease and is considered severe ( Figures 34-24 to 34-27 ). The pattern of bone loss may be horizontal or vertical, and the alveolar bone level is 6 mm or greater from the CEJ. Furcation involvement is readily viewed on posterior images. Bleeding on probing is evident. Clinically, pocket depths and attachment loss are greater than 6 mm, and furcation involvement and mobility are more severe.

Answer 28

type IV disease (advanced or severe periodontitis)

Question 29

what is commonly seen as pointed or irregular radiopaque projections extending from proximal root surfaces

Answer 29

calculus

Question 30

____may also appear as a ringlike radiopacity encircling the cervical portion of a tooth, a nodular radiopaque projection, or a smooth radiopacity on a root surface.

Answer 30

Calculus
