ADEX Patient Assessment and Diagnosis 3

Question 1

A patient reports taking warfarin for atrial fibrillation. Which laboratory value is most critical to review before initiating periodontal debridement?

Accepted Answer

International Normalized Ratio (INR)

Answer

The INR reflects anticoagulation status; an INR above the therapeutic range increases bleeding risk during periodontal procedures.

Question 2

Which radiographic technique best demonstrates the relationship between the alveolar crest and the CEJ in posterior sextants?

Accepted Answer

Bitewing radiograph

Answer

Bitewing radiographs show both maxillary and mandibular crestal bone levels in relation to the CEJ with minimal distortion.

Question 3

A patient presents with generalized 5-6 mm probing depths, radiographic bone loss, and heavy biofilm accumulation. According to the 2017 AAP classification, this most likely represents:

Accepted Answer

Generalized Stage III Grade B periodontitis

Answer

Generalized bone loss with probing depths ≥5 mm and heavy biofilm in the absence of rapid progression aligns with Stage III Grade B periodontitis.

Question 4

During an extraoral examination, the hygienist notes asymmetric swelling of the parotid gland bilaterally in a patient with a BMI of 16. Which condition should be considered?

Accepted Answer

Bulimia nervosa-related sialadenosis
