Chapter 25 Flashcards
Radiographs add each of the following to an assessment of periodontal disease except one. Which one is the exception?
C) The length of a clinical crown
Which of the following statements is false?
A) Radiographs assist with determining active versus arrested disease.
Which of the following is not a limitation of radiographs in the evaluation of periodontal disease?
A) They record an exaggerated assessment of actual clinical involvement of the disease.
Radiographs may assist in making the diagnosis of gingivitis.
FALSE
Radiographs may be used to evaluate crestal bone and interdental septal changes.
TRUE
In horizontal bone loss, the buccal and lingual plates and interdental bone have all been resorbed to relatively the same degree.
TRUE
Radiographs may assist in determining the distribution of periodontitis.
TRUE
Radiographs can reveal furcation involvement in the posterior teeth.
TRUE
Occlusal trauma can cause periodontal disease.
FALSE
Radiographs can serve as a baseline and as a means for determining treatment success or failure.
TRUE
Radiographs are two-dimensional images of three-dimensional objects.
TRUE
Changes in soft tissue can be demonstrated radiographically.
FALSE
Radiographs can distinguish treated versus untreated disease.
FALSE
Periodontal diseases affect both soft tissues (gingiva) and bone around the teeth.
TRUE
Radiographs document the amount of bone remaining rather than the amount lost.
TRUE
Vertical bone loss is the same diagnosis as angular bone loss.
TRUE
Localized bone loss is the same diagnosis as generalized bone loss.
FALSE
An amalgam overhang is a local contributing factor for periodontal disease.
TRUE
To image periodontal conditions, horizontal bitewing radiographs are preferred over vertical bitewing radiographs.
FALSE
Some practitioners prefer to expose radiographs used for the purpose of recording information regarding the periodontium at a lower kVp setting because of the high contrast it will produce.
FALSE
When taking multiple radiographs of the same region, varying the horizontal angulation slightly will compromise diagnosis.
FALSE
Evidence of bone loss up to 15 percent and crestal bone density that appears as a fuzzy cupping-out of the alveolar crest are radiographic signs of mild periodontitis.
TRUE
To be useful in the evaluation of periodontal disease, periapicals should be exposed using the paralleling technique.
TRUE
Name three local contributing factors for the development of periodontal diseases.
Amalgam overhangs, poorly contoured crown margins, and calculus.
Can radiographs reveal the effects of traumatic occlusion on the periodontium?
Yes.
Can gingivitis be detected radiographically?
No.
Can radiographs be used to differentiate treated versus untreated disease?
No.
How does the two-dimensional nature of radiographs limit their utility as a diagnostic aid?
Radiographs document the height and width of structures but do not demonstrate the third dimension of depth.
Which periodontal disease case type demonstrates bone loss greater than 30 percent?
Severe periodontitis.
What is the radiographic appearance of the lamina dura when gingivitis is present?
The same as a healthy status.
Describe the earliest radiographic evidence of periodontal disease.
A fuzzy, radiolucent cupping-out of the alveolar crest.
What is triangulation?
A widening of the periodontal ligament space.
What is the earliest type of periodontal disease in which furcation involvement is seen radiographically?
Moderate periodontitis.
