Viva Question and Answers Related to Polishing Agents Used in Dentistry

Here are 20 viva questions and answers related to polishing agents used in dentistry:

  1. What are polishing agents used in dentistry? Polishing agents are substances used to create a smooth and shiny surface on dental restorations, such as composite fillings, crowns, and bridges.
  2. What is the purpose of using polishing agents in dentistry? The primary purpose of using polishing agents is to improve the esthetics of dental restorations by creating a smooth, glossy surface that resists staining and plaque accumulation.
  3. What are some common types of polishing agents used in dentistry? Common types of polishing agents include abrasive pastes, polishing disks, rubber cups, and polishing strips.
  4. How do abrasive pastes work as polishing agents? Abrasive pastes contain fine particles of abrasive materials, such as silica or aluminum oxide, which help remove surface irregularities and stains from dental restorations when applied with a rotary instrument.
  5. What are the advantages of using abrasive pastes for polishing? Abrasive pastes are effective in removing surface stains, smoothing rough areas, and restoring a natural shine to dental restorations. Viva Question and Answers Related to Finishing and Polishing Instruments Used in Dentistry
  6. What precautions should be taken when using abrasive pastes for polishing? It is important to use the appropriate grit size of abrasive paste to avoid excessive removal of material from dental restorations and to prevent damage to surrounding tooth structure.
  7. How do rubber cups work as polishing agents? Rubber cups are used with polishing compounds to create a high-gloss finish on dental restorations. The rotary motion of the rubber cup helps distribute the polishing compound evenly and efficiently.
  8. What are some common polishing compounds used with rubber cups? Common polishing compounds used with rubber cups include diamond polishing paste, aluminum oxide paste, and zirconium oxide paste.
  9. What factors should be considered when selecting a polishing compound? Factors to consider when selecting a polishing compound include the type of dental material being polished, the desired level of shine, and any specific instructions from the manufacturer of the dental restoration. Viva Question and Answers Related to Routes of drug Administration in Pharmacology
  10. How do polishing disks work as polishing agents? Polishing disks are thin, flexible disks coated with abrasive materials that are used with a slow-speed handpiece to polish dental restorations. They are especially useful for contouring and polishing composite fillings.
  11. What are the advantages of using polishing disks? Polishing disks are easy to use, provide precise control during polishing procedures, and can be used to achieve a smooth, polished surface on dental restorations.
  12. What are polishing strips, and how are they used as polishing agents? Polishing strips are thin, flexible strips coated with abrasive materials that are used to polish interproximal surfaces and margins of dental restorations. They are particularly useful for finishing composite fillings.
  13. What are the key considerations for achieving optimal results when using polishing agents? Key considerations include selecting the appropriate type of polishing agent based on the material being polished, following the manufacturer’s instructions, using the correct polishing technique, and assessing the final result for esthetic satisfaction. Viva Question and Answers Related to Metallurgy in Dentistry
  14. How can polishing agents contribute to the longevity of dental restorations? Polishing agents help create a smooth surface on dental restorations, which can reduce plaque accumulation, prevent staining, and enhance the longevity of the restorations.
  15. What are some potential risks associated with improper use of polishing agents? Improper use of polishing agents can lead to over-polishing, excessive removal of material from dental restorations, damage to surrounding tooth structure, and compromised esthetics.
  16. What is the role of water irrigation during polishing procedures? Water irrigation helps cool the surface being polished, removes debris and excess polishing agents, and improves visibility during the polishing process.
  17. How should polishing agents be stored to maintain their efficacy? Polishing agents should be stored according to the manufacturer’s recommendations, typically in a cool, dry place away from direct sunlight and contamination.
  18. Can polishing agents be used on all types of dental restorations? Polishing agents are specifically designed for use on certain types of dental materials, such as composite resins, ceramics, and metals. It is important to select the appropriate polishing agent based on the material being polished.
  19. What are some innovations in polishing agents in recent years? Recent innovations in polishing agents include the development of nanocomposite polishing systems, which provide enhanced polishing efficiency and esthetic outcomes for composite restorations.
  20. How can dental professionals stay updated on the latest advancements in polishing agents? Dental professionals can stay updated by attending continuing education courses, reading scientific journals and publications, participating in professional conferences, and consulting with industry experts and colleagues. Viva Questions and Answers Related to Soldering in Dentistry
