Here are 30 viva questions and answers related to instruments used in periodontics:

  1. What is a periodontal probe, and what is its primary function?
    • Answer: A periodontal probe is a diagnostic instrument used to measure the depth of periodontal pockets and assess the health of the gingival sulcus.
  1. Explain the design and use of a Williams periodontal probe.
    • Answer: The Williams probe has a sharp, pointed tip and millimeter markings. It is used to measure pocket depths and assess the health of the periodontium.
  1. What is the purpose of a periodontal explorer?
    • Answer: A periodontal explorer is used to detect irregularities on tooth surfaces, including calculus and rough areas on root surfaces.
  1. Differentiate between a Gracey curette and a universal curette.
    • Answer: A Gracey curette is designed for specific tooth surfaces, while a universal curette can be used on multiple surfaces. Gracey curettes are area-specific and have one curved and one straight cutting edge.
  1. How is a furcation probe different from a periodontal probe?
  1. Describe the function of a gingival retraction cord in periodontics.
    • Answer: A gingival retraction cord is used to displace the gingival tissue temporarily, providing better access for impression materials and procedures.
  1. What are periodontal scalers, and how are they different from curettes?
    • Answer: Periodontal scalers are designed to remove calculus from tooth surfaces, while curettes are used for both calculus removal and root planing.
  1. Explain the purpose of a periodontal knife in periodontal surgery.
  1. How do ultrasonic scalers differ from hand scalers in periodontics?
    • Answer: Ultrasonic scalers use high-frequency vibrations to remove calculus, while hand scalers require manual pressure for calculus removal.
  1. What is the role of a periodontal chisel in surgical procedures?
    • Answer: A periodontal chisel is used to make precise incisions in the bone during periodontal surgery.
  1. Explain the purpose of a bone file in periodontics.
    • Answer: A bone file is used for smoothing and shaping bone surfaces after surgical procedures, promoting proper healing.
  1. Differentiate between a periodontal probe and a periodontal pocket marker.
    • Answer: A periodontal probe measures pocket depth, while a pocket marker is used to indicate the margins of a periodontal pocket.
  1. What is the function of a periotome in periodontal surgery?
  1. Explain the use of a gingivectomy knife in periodontal procedures.
    • Answer: A gingivectomy knife is employed to remove excess gingival tissue, reshaping the gumline for esthetic or therapeutic purposes.
  1. Describe the characteristics of a periodontal microsurgical instrument.
    • Answer: Periodontal microsurgical instruments are small, delicate tools designed for precise and minimally invasive procedures under magnification.
  1. What is the function of a bone grafting instrument in periodontics?
    • Answer: A bone grafting instrument is used to prepare and place bone graft materials during periodontal bone regeneration procedures.
  1. Explain the role of a periodontal syringe in periodontal therapy.
  1. Differentiate between a straight and contra-angle handpiece in periodontal surgery.
    • Answer: A straight handpiece is used for access in open areas, while a contra-angle handpiece is designed for better access in confined spaces during periodontal surgery.
  1. How does a periodontal dressing instrument aid in post-surgical care?
    • Answer: A periodontal dressing instrument is used to manipulate and place periodontal dressings, aiding in the protection and stabilization of surgical sites.
  1. Describe the purpose of a periodontal endoscope in periodontics.
    • Answer: A periodontal endoscope is used for visualizing subgingival areas during nonsurgical or surgical periodontal procedures.
  1. Explain the function of a crown lengthening instrument in periodontal surgery.
    • Answer: A crown lengthening instrument is used to remove excess gum tissue and bone, exposing more of the tooth structure for restorative purposes.
  1. What is the significance of a periodontal dressing scissors in post-surgical care?
  1. How does a periodontal laser differ from traditional periodontal instruments?
    • Answer: A periodontal laser uses focused light energy to perform soft tissue procedures, offering a minimally invasive alternative to traditional instruments.
  1. Describe the purpose of a periodontal microbrush in periodontics.
    • Answer: A periodontal microbrush is used for the controlled application of medications, hemostatic agents, or other substances in periodontal therapy.
  1. Explain the function of a periodontal surgical curette.
    • Answer: A periodontal surgical curette is designed for precise root planing and debridement in surgical periodontal procedures.
  1. What is the primary use of a tissue punch in periodontal surgery?
    • Answer: A tissue punch is used to create a precise opening in the gingival tissue for implant placement or other surgical procedures.
  1. Differentiate between a periodontal elevator and a luxator in tooth extraction.
    • Answer: A periodontal elevator is used to elevate teeth from their sockets, while a luxator is designed to luxate or loosen teeth before extraction.
  1. Explain the purpose of a periodontal pressure pack in post-surgical care.
  1. What is the function of a periodontal microsurgical needle holder?
    • Answer: A periodontal microsurgical needle holder is used to grasp and control delicate needles during microsurgical procedures in periodontics.
  1. How is a periodontal microsurgical scissor different from traditional surgical scissors?
