ADEX Patient Assessment and Diagnosis 4

Question 1

A patient reports jaw pain, clicking on opening, and limited mouth opening of 28 mm. These findings are most consistent with:

Accepted Answer

Temporomandibular joint disorder (TMD)

Answer

Jaw pain, TMJ clicking, and restricted opening (<40 mm) are hallmark signs of temporomandibular disorder.

Question 2

During a periodontal assessment, the clinical attachment level (CAL) is calculated by:

Accepted Answer

Adding probing depth to recession or subtracting pseudopocket depth from probing depth

Answer

CAL = probing depth + recession when the gingival margin is apical to the CEJ, or CAL = probing depth − pseudopocket when the margin is coronal.

Question 3

A 45-year-old patient presents with smooth, shiny, cupped-out lesions on occlusal surfaces of mandibular molars and lingual erosion of maxillary anteriors. The most likely etiology is:

Accepted Answer

Bulimia nervosa with acid regurgitation

Answer

Lingual erosion of maxillary teeth combined with cupped occlusal surfaces suggests chronic acid exposure from purging (perimolysis).

Question 4

When assessing salivary flow, hyposalivation is defined as an unstimulated whole saliva flow rate of less than:

Accepted Answer

0.1 mL/min

Answer

Hyposalivation is clinically defined as unstimulated whole saliva flow below 0.1 mL/min.

Question 5

Which of the following medications most commonly causes gingival enlargement that would be identified during a periodontal assessment?

Accepted Answer

Amlodipine (calcium channel blocker)

Answer

Calcium channel blockers such as amlodipine are among the drug classes most associated with drug-influenced gingival enlargement.
