Title: Q%201.%20The%20Compton%20effect%20is


1
  • Q 1. The Compton effect is
  • A. Photons entire energy is used to eject an
    electron
  • B. Photons entire energy is used to eject an
    electron and low energy photon
  • C. Photons entire energy is used to eject an
    negative and one positive electron
  • D. Photon energy is absorbed by colliding by
    hydrogen nuclei

2
  • Q2. Accelerated fractionation is described as
  • 1.7 to 2.0 Gy, 5 fraction/week to 70.0Gy
  • B. Reduction of the number of fraction with an
    increase of the daily fraction
  • Increase both the number of fractions and the
    total dose
  • Hybrid state of hypofractionation and
    hyperfractionation

3
  • Q3. The characteristic property of particulate
    radiation in comparison to photo radiation in
    dosimetry is
  • A. falloff region is rapid
  • B. skin sparing effect is more
  • C. higher the energy used, the greater the depth
    of penetration
  • D. progressive fall of tissue dose

4
  • Q4 Back scattering to large metallic retardation
    in tooth during radiotherapy can be treated by
  • A. Replacement with composite restoration
  • B. Extraction before the radiotherapy begin
  • C. Cover with custum made floride tray
  • D. Exclude this area during dosimetry design

5
  • Q5. Which option is best suited for trismus with
    dynamic bite openers
  • A. 20 minutes serum two times per day
  • B. 30 minutes serum two times per day
  • C. 30 minutes serum three times a day
  • D. 20 minutes serum once a day

6
  • Q6) Which figure indicates severe mucosal changes
    in radiotherapy

A
B
D
C
7
  • Q7) In which candidate you advice extraction
    before radiation
  • Tissue impacted mandibular third molar
  • Bony impacted mandibular third molar
  • Mandibular molar in doses of 65 Gy
  • Maxillary molar in doses of 65 Gy

8
  • Q8Which of the following sentence is true
  • A translucent boggy mucosa with prominent
    telangiectasia is good to tolerate denture.
  • Palatine salivary gland fibrosis do not lead to
    difficulty in customary postdam area movement.
  • Light polishing of tissue surface of denture is
    recommended during or after radiotherapy.
  • Prosthesis should not fabricated immediately
    after radiotherapy.

9
  • Q9) All are preventive measure of radiotherapy
    except
  • A) Fluoride gel application 1hr before bedtime
    but at pre-radiation and during radiation phase.
  • B) CPP-ACP at anytime during the day
  • C) Fluoride tooth paste for normal tooth
    brushing.
  • D) Remineralizing chewing gum during daytime hour
    (four times) for 20 minutes

10
  • Q10) Which type of article provide the best
    evidence among these
  • Noise analysis
  • Case report
  • Systematic review
  • Randomized controlled trial
