Questions and Answers

Which of the following is the primary function of a luxator during a tooth extraction?

  • Elevating the gingiva off the bone.

Study Notes

Indications

  • Extractions are indicated in cases of periodontal disease.
  • They can address tooth resorption.
  • Extractions may be necessary for teeth with caries.
  • Malocclusion can be an indication for extraction.
  • Persistent deciduous teeth sometimes require extraction.
  • Non-functional malformed teeth may need to be extracted.

Patient Preparation

  • Securing the airway is a key step.
  • Preoperative antibiotics may be administered, but their effectiveness can be limited due to bacteria often being stuck in biofilm and a lack of blood flow in certain areas.
  • Analgesia is important for patient comfort.

Equipment

  • Luxators cut periodontal ligaments and are thin.
  • Elevators wrap around teeth being extracted.
    • They are thick and curved.
    • Elevators help elevate teeth away from bone.
  • Periosteal elevators raise gingiva off the bone.
  • Root tip picks retrieve tooth fragments and are thin and pointy.
  • Extraction forceps grasp and remove teeth.
  • Root tip forceps retrieve tooth remnants and have a thin, long blade.
  • High-speed handpieces are air-driven and can have water turned on.

Burs

  • Round burs are suitable for root canals
  • Useful for cavity preparation.
  • Can cut small teeth.
  • Used to burr bone.
  • Fissure cross burs feature a small taper
  • They are long.
  • Contain cutting edges.
  • Burs can cut teeth
  • Useful for cavity preparation
  • Good for root canals.
  • Inverted burs are trapezoid crosscut
  • They are good for undercutting.
  • Inverted burs are used for cavity preparation.
  • Pear burs enable all-purpose cavity preparation.
  • They feature a round top with a flat top.
  • Diamond burs lack cutting edges
  • Provides smooth bone cutting.

Complications

  • Dry socket, or alveolar osteitis, is characterized by painful inflammation and bone infection.
  • Hemorrhage (excessive bleeding) can occur.
  • A retained tooth might lead to issues
  • Trauma can be a complication.
  • Oral nasal fistula (abnormal opening) may develop.

Important Considerations

  • If there's a hemorrhage in the mouth, apply gauze on and off the extraction site.
  • Suture sockets and do not flush open sockets, because it doesn't need to be open to drain.
  • Flush the sulcus.
  • Make sure there's bleeding in the socket.
  • Close the socket
  • Ensure there's no tension.

Post-operative Care

  • Manage pain.
  • Consume soft food for 7–14 days.
  • Watch for bloody discharge.
  • Sutures if necessary
  • Follow-up rechecks are important.
