Final; Radiographic Interpretation of Dental Caries Flashcards
Bitewings have increased the diagnosis of small dental carious lesions which cannot be observed clinically by what percentage
250%
What two things happen to enamel and dentin by the bacterial acid products
decalcification
cavitation
What two things can dental caries progress into
pulp inflammation
necrosis of the pulp
True or False
Radiographs can replace clinical examination
False; they cannot, it can supplement clinical examination
Radiographic imaging of caries will look radiolucent or radiopaque
radiolucent
There is increased or decreased absorption of the x-ray beam as it passes through the carious lesion
decreased; making it appear darker
What is the procedure/systematic approach for looking at a radiograph
examine bone and bony structures
examine alveolar bone
examine teeth
What thing is definitely needed in order to properly diagnose inter proximal caries regarding the radiograph
no horizontal overlap
open contacts
Which type of caries are nearly impossible to determine radiographically
incipient
What are the four classifications of dental caries
occlusal
proximal
cemental/root
recurrent
What is the characteristic shape of caries on a radiograph
“inverted mushroom”
initial linear penetration through enamel “explodes” once in dentin
Where will inter proximal caries most likely form
gingival to the contact point
The classes description of the shape of a carious lesion (incipient) in enamel is what
chevron
This is a radiolucent region that appears directly adjacent to enamel due to sharply defined difference between the enamel and dentin, DEJ; can lead to false-positive interpretation
Mach Band
These are caries adjacent to a restoration, due to inadequate margins or inadequate excavation; need clinical examination
recurrent caries
