State PSC PYQ - 3 Questions

1
State PSC PYQ
Which of the following is NOT an objective of the fluid wax impression technique?
1) It is used to record the stress-bearing areas in functional form
2) It is used to record the non-stress-bearing areas in functional form
3) It is used to record the non-stress-bearing areas in anatomic form
4) It is used to obtain maximum extension of the peripheral borders of the denture

πŸ“ Explanation:

The technique records stress-bearing areas in functional form, non-stress-bearing areas in anatomic form, and helps obtain maximum peripheral extension. Recording non-stress-bearing areas in functional form is NOT one of its objectives.

Which restorative material is most suitable for managing root caries in patients with xerostomia?

  1. Silver amalgam
  2. Glass ionomer cement
  3. Hybrid composite resin
  4. Flowable composite resin

πŸ“ Explanation:

Glass ionomer cement is the most suitable material for managing root caries in patients with xerostomia (dry mouth) due to its unique properties. It can bond to the tooth structure in a moist environment and, crucially, it releases fluoride, which helps prevent further decay in patients with reduced salivary flow and high caries risk.

What is a key characteristic of dental hybrid composite resin materials that contributes to their strength, polishability, and wear resistance?
1) The use of only small filler particles
2) The use of only larger filler particles
3) The combination of large and small filler particles
4) Filler content of 20%-30%

πŸ“ Explanation:

  • Hybrid composite resins get their beneficial properties from a mix of filler particle sizes.
  • Larger particles contribute to strength and wear resistance, while smaller particles fill the gaps between the larger ones, allowing for better polishability and a smoother surface finish.
  • This combination provides a balance of strength, polishability, and wear resistance, making them a versatile dental material.
