How many diagnoses does each tooth need?
2 diagnoses
What are the diagnoses that each tooth needs?

(maybe perio & restorative also)
What is the first question to ask your patient that is in pain?
what is your chief complaint?
When you ask a patient to point to the tooth that hurts, you are asking them if they can:
localize the source of pain
If the source of pain is purely pulpal, your patient will likely:
be unable to localize the source of pain
Why might the patient be unable to localize the source of pain if it is purely pulpal?
pulpal pain = diffuse pain
How might we describe purely pulpal pain?
diffuse pain
It is important to understand ____ before proceeding
the chief complaint
The ____ is what brought the patient here
chief complaint
The objective of clinical testing is to:
find & confirm the etiology of the patient’s CC
Conclusions in the study “Associations between Pain Severity, Clinical Findings, and Endodontic Disease: A Cross-Sectional Study” reveals that percussion hypersensitive on healthy adjacent tooth may reveal a:
lowered pain threshold and heightened pain sensitization
Conclusions in the study “Associations between Pain Severity, Clinical Findings, and Endodontic Disease: A Cross-Sectional Study” reveals that percussion hypersensitive on healthy adjacent tooth may reveal a lowered pain threshold and heightened pain sensitization. It is also possible that the two commonly performed mechanical sensory tests, percussion and palpation sensitivity, may detect:
different aspects of endodontic pathophysiology and pain processing
Performed based on CC:
clinical testing
Some examples of clinical testing include: (5)
