Oral Pathology Keys
1. Review medical history: smoking, diabetes, medications, radiation therapy,
cancer history
2. Review dental history: look for causes of tissue trauma
3. Extraoral and Intraoral Exams (palpation of lymph nodes, lesions): size, soft,
firm, fixed
4. Etiology: calculus, plaque, habits, appliances
5. Pain: If no pain and it looks like it should hurt, this can be a red flag.
6. Duration: new; present longer than 2 weeks
7. Frequency: new or recurring
8. Pattern: localized or generalized; unilateral
9. Location: attached gingiva, mucosal tissue, tongue, FOM, retromolar pad
10. Palpation: does surface wipe off, bleeding, soft, firm, fixed
11. Radiographic findings: crestal bone loss, -luscency, -opacity, calculus
present

1. Complete extraoral checks. Ask patient about any changes or irregularities.
2. Check all intraoral features. Have a standard protocol to prevent missing
anything. Check lymph nodes; lateral border of tongue; floor of the mouth;
hard palate; and retromolar pad.
3. If you find a lesion, ask about it. Look for explainable causes. Rule out
trauma.
4. Do not wait until next cleaning to check lesion. Bring back in 2 weeks if
necessary.
5. If you have no idea, ask your dentist to evaluate. May need to refer to a
Periodontist or OMS.
6. Always be looking. If you are not looking, you may not notice a lesion
until it has progressed too far.
Considerations for when to biopsy
1. You did not find a plausible reason for why the
lesions has occurred.
2. Characteristics: firm and fixed
3. Location: Not limited by location; check problem
areas noted above.
4. Duration: More than two weeks
5. Worsening symptoms: Enlargement, increased pain
6. Bone loss
