A patient presents for routine examination. Radiographically, the heavily restored lower right first molar shows apical radiolucencies of both the mesial and distal roots. The patient does not recall any past symptoms. What is the most likely diagnosis?
Acute suppurative periodontitis
Chronic periodontal abscess
Irreversible pulpitis
Chronic apical periodontitis
The external root surface anatomy reflects the internal pulp chamber anatomy.
true
false
Root canal treatment without rubber dam is within the standard of care if insufficient tooth structure exists for isolation.
True
False
A sudden change in the radiographic "density" of a root canal is a strong indication that canal calcification has occured in the apical region.
true
false
A basic objective of cleaning and shaping a root canal is to allow disinfecting irrigants access to the apical one-third of the root canal.
true
false
A wire measurement radiograph that is 2 mm or more from the ideal apical position is okay for determining working length with no subsequent radiographs needed.
true
false
Patency filing is accomplished with small K-files, either #10 or #15.
true
false
The advantage of crown down technique is that it removes infected coronal dentin and obstructions before apical preparation and enlarges canals incrementally.
True
False
A tooth with chronic apical abscess will not respond to pulpal vitality tests, radiographically will not exhibit an apical radiolucency, and will have a sinus tract associated with the tooth.
true
false
A tooth with symptomatic apical periodontitis will have an acutely painful response to biting pressure or percussion.
true
false
