Exam 2 Radiographic Interpretation Flashcards
X-rays are differentially ___________ as they pass through ___________ of tissue and as a result they are __________ to different degrees
- absorbed
- various types
- attenuated
Dense structures _________ more x-rays
absorb
Metal is most ___________.
Air is most _____________.
- radiopaque
- radiolucent
How are x-rays used in diagnosis of perio and caries?
The affected tissue will absorb LESS x-rays and thereby exhibit different degrees( changes in the gray scale) of absorption that will display in various degrees of radiopacity and radiolucency.
What is the causes of loss of alveolar bone?
1) Chronic periodontitis
2) Agressive periodontitis
3) Necrotizing Ulcerative Periodontitis
What are the results of alveolar bone loss?
1) Horizontal
2) Vertical (1, 2, 3 wall defects) and circumferential
3) Interproximal crater
4) Furcation involvement
