What did the 2023 · Session 1 paper ask?

Three of the paper's 120 questions, each with the answer and our explanation. Questions are shown exactly as worded on the paper. The explanations are ours.

1. Sample 1 of 3 · Periodontology

   Subclinical gingivitis is:

   1. a,Characterized by vascular proliferation
   2. b,Characterized by predominantly lymphocytes microscopically
   3. c,Characterized by predominantly plasma cells microscopically
   4. d,Characterized by erythema, bleeding on probing
   5. e,Characterized by increased crevicular fluid flow and infiltration of sulcular and junctional epithelium by polymorphonuclear leukocytes

   Show the answer

   Correct answer: e · Characterized by increased crevicular fluid flow and infiltration of sulcular and junctional epithelium by polymorphonuclear leukocytes

   Subclinical (early) gingivitis features increased crevicular fluid flow and neutrophil infiltration of the junctional/sulcular epithelium before clinical signs appear.

2. Sample 2 of 3 · General

   CAD/CAM preparation should not:

   1. a,Have thin angles
   2. b,Have parallel walls less than 6°
   3. c,Have undercuts
   4. d,Have contacts with adjacent teeth
   5. e,All of the above

   Show the answer

   Correct answer: e · All of the above

   A CAD/CAM preparation must avoid thin/sharp angles, near-parallel (<6°) walls, undercuts and broken proximal contacts so the scanner and mill can reproduce it accurately — all of the above are to be avoided.

3. Sample 3 of 3 · Anesthesia & Pharma

   Choose the correct statement:

   1. a,Aspirin should always be stopped at least 7-10 days before any surgical procedure
   2. b,Aspirin should always be stopped 5 days before any surgical procedure
   3. c,Aspirin should always be stopped 2-3 days before any surgical procedure
   4. d,Aspirin should always be stopped 12 days before any surgical procedure
   5. e,None of the above

   Show the answer

   Correct answer: e · None of the above

   Routine low-dose aspirin generally need NOT be stopped for minor dental surgery, and blanket rules to stop it for a fixed number of days are outdated — so none of the categorical statements is correct.

Is there a PDF of the 2023 · Session 1 paper?

No PDF here: Enamel has all 120 questions of this paper, each explained, in the app.

In the app the paper is a set of its own: answer each question, then read the key and the written explanation.
