What did the 2020 · Session 1 paper ask?

Five 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 5 · Endodontics

   Localization of the source of dental pain is a challenge in case of:

   1. a,Acute irreversible pulpitis
   2. b,Acute apical periodontitis
   3. c,Acute reversible pulpitis associated with apical periodontitis
   4. d,Acute irreversible pulpitis associated with apical periodontitis
   5. e,Asymptomatic irreversible pulpitis

   Show the answer

   Correct answer: a · Acute irreversible pulpitis

   Localizing the offending tooth is hardest in acute irreversible pulpitis, because pulpal pain is poorly localized (the pulp lacks proprioceptors) until the periapex is involved.

2. Sample 2 of 5 · Operative & Materials

   A glass fiber post is cemented inside the root canal with the following procedure:

   1. a,Etching, Bonding, light cured resin cement
   2. b,Etching, Bonding, dual cured resin cement
   3. c,Self-adhesive resin cement without etching and bonding
   4. d,b or c
   5. e,Glass ionomer cement

   Show the answer

   Correct answer: d · b or c

   A glass-fibre post is luted with either an etch-and-bond plus dual-cured resin cement or a self-adhesive resin cement — b or c.

3. Sample 3 of 5 · General

   In dental clinic, in front of a patient suffering from an Addison syndrome:

   1. a,an oral hyperpigmented mucosa is found
   2. b,an arterial hypertension must be considered
   3. c,a hyperglycemia must be foreseen
   4. d,stress and pain are to be avoided
   5. e,a+d

   Show the answer

   Correct answer: e · a+d

   Addison's disease causes mucosal hyperpigmentation and a poor stress response, so pigmentation is seen and stress/pain must be minimized (adrenal-crisis risk) — a+d.

4. Sample 4 of 5 · General

   In comparison with the conventional fabrication the CAD/CAM technology has many advantages such as:

   1. a,increase risk of error
   2. b,heavy initial investment
   3. c,time saving
   4. d,the utilization of software must be learned first
   5. e,a and c

   Show the answer

   Correct answer: c · time saving

   CAD/CAM offers time saving over conventional fabrication (its key advantage), whereas heavy initial cost and a learning curve are drawbacks, so the advantage is time saving (c).

5. Sample 5 of 5 · Oral Surgery

   Multinucleated giant cells are associated with: (1) plasmocytoma (2) odontogenic myxoma (3) hyperparathyroidism (4) tuberculosis (5) osteoclastoma

   1. a,(1) (3) (4)
   2. b,(2) and (3)
   3. c,(2) and (4)
   4. d,(3) (4) (5)
   5. e,(2) (4) (5)

   Show the answer

   Correct answer: d · (3) (4) (5)

   Multinucleated giant cells appear in hyperparathyroidism (brown tumour), tuberculosis and osteoclastoma (giant cell tumour) — (3),(4),(5).

Is there a PDF of the 2020 · 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.
