What did the 2021 · 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 · Pedo & Ortho

   Mouth breathing is considered:

   1. a,Normal in people with dark circles
   2. b,Pathological
   3. c,Normal in children with elongated faces
   4. d,Normal in children with labial inclusion
   5. e,None of the above

   Show the answer

   Correct answer: b · Pathological

   Habitual mouth breathing is pathological; it can alter facial growth and the dentition and warrants investigation/management.

2. Sample 2 of 3 · Periodontology

   The principle of saving dental tissues means:

   1. a,Carving two sides of the tooth
   2. b,Reduce the space sufficient to place the prosthetic element
   3. c,Place the size limit in supra gingival
   4. d,Reduce 0.5 mm of all walls
   5. e,Place the size limit in juxta-gingival

   Show the answer

   Correct answer: b · Reduce the space sufficient to place the prosthetic element

   Tissue conservation means reducing only enough tooth structure to accommodate the prosthetic material, avoiding unnecessary removal.

3. Sample 3 of 3 · Prosthodontics

   A patient comes to your clinic after a trauma with an alveolar fracture at the central incisor, action to be taken:

   1. a,No systematic retainer
   2. b,Retainer for weeks for comfort
   3. c,Flexible retainer lasting four weeks
   4. d,Permanent retainer
   5. e,None of the above

   Show the answer

   Correct answer: c · Flexible retainer lasting four weeks

   An alveolar (dento-alveolar) fracture is stabilized with a flexible splint for about four weeks to allow bony and periodontal healing.
