What did the 2019 · Session 1 paper ask?

Four 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 4 · Prosthodontics

   Orientation grooves are used to define:

   1. a,The axis of insertion of the prosthesis
   2. b,The depth of cut in the preparation of a tooth
   3. c,The axis of insertion of the print
   4. d,Are made with a steel ball tool
   5. e,The axis of insertion of the provisional tooth

   Show the answer

   Correct answer: b · The depth of cut in the preparation of a tooth

   Depth-orientation grooves are cut to gauge the amount of tooth reduction during preparation, ensuring uniform clearance.

2. Sample 2 of 4 · Anesthesia & Pharma

   All of the following antibiotics can increase the frequency and severity of bleeding incidents related to vitamin K antagonists except:

   1. a,Macrolides
   2. b,Metronidazole
   3. c,Amphotericin B
   4. d,Ampicillin
   5. e,Tetracycline

   Show the answer

   Correct answer: c · Amphotericin B

   Macrolides, metronidazole, ampicillin and tetracyclines can potentiate vitamin-K-antagonist anticoagulation; amphotericin B does not, so it is the exception.

3. Sample 3 of 4 · Operative & Materials

   Salvaging a failed fixed implant case may lead to implant supported removable partial denture. This includes:

   1. a,Poorly positioned dental implant
   2. b,Failure in osseointegration
   3. c,Fracture of implant components under a fixed implant restoration
   4. d,A+B
   5. e,All of the above

   Show the answer

   Correct answer: e · All of the above

   A fixed implant case may have to be converted to an implant-supported removable denture when implants are poorly positioned, fail to osseointegrate, or components fracture — all of the above.

4. Sample 4 of 4 · 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 are seen in hyperparathyroidism (brown tumour), tuberculosis (granulomas) and osteoclastoma (giant cell tumour) — (3),(4),(5).
