What did the 2022 · 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 · Radiology & Diagnosis

   Palpation of lymph nodes should be done to note:

   1. a,Lymph node enlargement
   2. b,Tenderness
   3. c,Mobility and consistency
   4. d,All of the above
   5. e,None of the above

   Show the answer

   Correct answer: d · All of the above

   Lymph-node palpation assesses enlargement, tenderness, and mobility/consistency to help distinguish inflammatory from neoplastic nodes — all of the above.

2. Sample 2 of 5 · Periodontology

   Macrophages contained within the periodontium, function as which of the following?

   1. a,Phagocytosis
   2. b,Collagen destruction enzymes
   3. c,Initiation of T-Cell production
   4. d,b and c
   5. e,All of the above

   Show the answer

   Correct answer: e · All of the above

   Periodontal macrophages perform phagocytosis, release tissue-degrading enzymes and help initiate T-cell responses — all of the above.

3. Sample 3 of 5 · Radiology & Diagnosis

   Areas of rarefaction are evident on radiographic examination in which of the following:

   1. a,When tooth is responsive to cold
   2. b,When tooth is responsive to percussion
   3. c,When tooth is responsive to hot
   4. d,When tooth fracture has been identified
   5. e,When the cortical layer of bone has been eroded

   Show the answer

   Correct answer: e · When the cortical layer of bone has been eroded

   A periapical radiolucency (rarefaction) becomes visible once the lesion erodes the cortical bone, which is needed for radiographic detection.

4. Sample 4 of 5 · General

   In order to extract 2nd lower premolar:

   1. a,We should always make local infiltration
   2. b,We should always make mandibular bloc
   3. c,We should always make intraligamentary injection
   4. d,All of the above
   5. e,None of the above

   Show the answer

   Correct answer: e · None of the above

   No single anaesthetic technique is mandatory for a lower second premolar; the choice depends on the case, so none of the absolute statements is correct.

5. Sample 5 of 5 · 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 dental surgery, so the categorical 'always stop for X days' statements are all incorrect — none of the above.
