viva question and answers related to the classification of dental cements

 

  1. What are dental cements, and what is their primary function in dentistry?
    • Dental cements are materials used in dentistry to bond, seal, or fill dental structures.
  2. How are dental cements classified based on their setting reaction?
    • Dental cements can be classified as: a. Chemical-cure cements b. Light-cure cements c. Dual-cure cements
  3. Explain chemical-cure dental cements. Give an example.
    • Chemical-cure cements set through a chemical reaction, without the need for light. An example is zinc phosphate cement.
  4. What are the advantages of chemical-cure dental cements?
    • They have a long working time, good strength, and minimal shrinkage.
  5. Explain light-cure dental cements. Give an example.
    • Light-cure cements use a curing light to set. An example is composite resin cement.

  1. What are the advantages of light-cure dental cements?
    • They offer precise control during placement, reduced working time, and minimal post-operative sensitivity.
  2. Explain dual-cure dental cements. Give an example.
    • Dual-cure cements can set both chemically and with light. An example is dual-cure resin cement.
  3. What are the advantages of dual-cure dental cements?
    • They provide versatility and are suitable for situations with limited light access.
  4. How are dental cements classified based on their clinical use?
    • Dental cements can be classified as: a. Luting cements b. Restorative cements c. Liner bases
  5. Explain luting cements and their primary use.
    • Luting cements are used to bond restorations to tooth structures, such as crowns, bridges, and inlays.
  6. Give an example of a luting cement.
    • Zinc phosphate cement is an example of a luting cement.
  7. Explain restorative cements and their primary use.
    • Restorative cements are used to build up and repair teeth, such as in the placement of dental fillings.
  8. Give an example of a restorative cement.
    • Glass ionomer cement is an example of a restorative cement.
  9. Explain liner bases and their primary use.
    • Liner bases are used to protect the pulp from irritation and improve the adaptation of restorative materials.

Viv questions in properties of dental materials

  1. Give an example of a liner base material.
    • Calcium hydroxide is an example of a liner base material.
  2. How are dental cements classified based on their composition?
    • Dental cements can be classified as: a. Zinc oxide-eugenol cements b. Zinc oxide non-eugenol cements c. Glass ionomer cements d. Composite resin cements
  3. What are the characteristics of zinc oxide-eugenol cements?
    • They provide sedative and soothing properties, making them suitable for temporary and intermediate restorations.
  4. Give an example of a zinc oxide-eugenol cement.
    • IRM (Intermediate Restorative Material) is an example.
  5. What are the characteristics of zinc oxide non-eugenol cements?
    • They lack the sedative properties of eugenol but are used for similar purposes.

viva question and answers related to Pharmacodynamics

  1. Give an example of a zinc oxide non-eugenol cement.
    • TempBond NE is an example.
  2. What are the characteristics of glass ionomer cements?
    • They have good adhesion to tooth structure and can release fluoride.
  3. Give an example of a glass ionomer cement.
    • Fuji IX is an example.
  4. What are the characteristics of composite resin cements?
    • They offer excellent esthetics and strength, making them suitable for anterior restorations.
  5. Give an example of a composite resin cement.
    • Variolink Esthetic is an example.
  6. How are dental cements classified based on their solubility?
    • Dental cements can be classified as: a. Water-based cements b. Resin-based cements
  7. Explain water-based cements and their solubility.
    • Water-based cements are soluble in water and can release fluoride. Glass ionomer cements fall into this category.
  8. Explain resin-based cements and their solubility.
    • Resin-based cements are not water-soluble and provide superior adhesion. Composite resin cements are examples.
  9. How are dental cements classified based on their application in the oral cavity?
    • Dental cements can be classified as: a. Cavity liners b. Bases c. Adhesives
  10. What is the role of cavity liners in restorative dentistry?
    • Cavity liners are used to protect the pulp and provide a barrier between the restoration and the tooth structure.
  11. Give an example of a dental cement used as a cavity liner.
    • Calcium hydroxide is commonly used as a cavity liner.
