INTERPRETATION IN RADIOLOGY

Question 1

Radiographs are a valuable aid in the:

Answer 1

Diagnosis of periodontal disease

• Determination of the prognosis, and
• Evaluation of the outcome of treatment

Question 2

types of radiographs

Answer 2

PAN
Bitewing
Periapical

Question 3

Radiographs are helpful in evaluation of:

Answer 3

Amount of bone present
Condition of alveolar crests
Bone loss in furcation areas
Width of the Periodontal Ligament (PDL) space
Local factors which can cause or intensify periodontal disease

Question 4

Radiographic assessment of periodontal condition

Answer 4

Amount of bone present
Condition of alveolar crest
Bone loss in furcation area
Width of PDL space
Local initiating factors (calculus, overhanging restorations)
Root length and morphology
Crown root ratio
Anatomical considerations
Pathological considerations (caries, periapical lesions, root resorption)

Question 5

Changes in interdental septa includes:

Answer 5

Crestal bone loss
lamina dura
Crestal density
height and contour of bone

Question 6

Radiological changes of the supporting tissues

Answer 6

Bone loss from periodontal disease may extend into the furcations of multirooted teeth
Initially, seen as widening of the PDL space at crest of the furcation
A lesion progresses, the bone loss progresses apically
