Ultrasonic scaler

  1. 1. ULTRASONIC SCALER Presented By: Lethane Sakiwat • Definition & Use • Types & Parts • Difference of Manual Scaler & Ultrasonic Scaler • Advantages And Disadvantages • 4 Ultrasonic Insert/ Tip
  2. 2. DENTAL ASSISTING an ultrasonic instrument with a tip for supplying high-frequency vibrations used to remove plaque and calculus from teeth and bits of inflamed tissue from the walls of the gingival crevice.
  3. 3. 2. Piezoelectric - vibration is linear- two sides of tip are active DENTAL ASSISTING 1. Magnetostrictive - pattern of vibration is elliptical- all sides of the tip are active
  4. 4. Hand piece Cable Water Speed Control Power Switch Ultrasonic Inserts/ Tips Power Control / Variable Speed Control DENTAL ASSISTING Hand piece
  5. 5. Manual Scaler Ultrasonic Scaler Safety Face Mask, Gloves Face Mask, Gloves, Safety Glasses (for high Frequency Oscillating instrument) Irrigation Medium/ Coolant Antimicrobial Irrigants e.g. Chlorhexidine, Iodine Solution Water Traction More space Less space Less Efficient More Efficient Longer Lesser Calculus Removal on Multi-rooted-teeth a. Efficiency b. Treatment Time DIFFERENCE OF MANUAL SCALER & ULTRASONIC SCALER Difference
  6. 6. DENTAL ASSISTING
  7. 7. DENTAL ASSISTING a. Blade or Nib b. Shank c. Handle
  8. 8. Sharpening not required Easier to debride inaccessible furcations Less tissue distention Reduce operator fatigue ADVANTAGES
  9. 9. Water control Evacuation needed Production of contaminated aerosols Potential occupational hazard (noise/vibration) Requires power supply DISADVANTAGES
  10. 10. DENTAL ASSISTING
  11. 11. DENTAL ASSISTING - For tenacious or easily removed extrinsic stain
  12. 12. DENTAL ASSISTING
  13. 13. DENTAL ASSISTING -For light to heavy debris removal
  14. 14. DENTAL ASSISTING - For light to moderate deposit removal
  15. 15. DENTAL ASSISTING - for removal of orthodontic cement
  16. 16. DENTAL ASSISTING Light to moderate deposits • Heavy deposits Orthodontic cement • Light to moderate deposits in periodontal pockets Moderate to heavy deposits in Periodontal pockets • • • • •
  17. 17. • Gum Disease • Terms
  18. 18. DENTAL ASSISTING
  19. 19. DENTAL ASSISTING
  20. 20. DENTAL ASSISTING Debride / Debridement – refers to the necessary palque calculus that have accumulated on the teeth. Distention – to swell out/ expand from or as of from internal pressure Furcation – the anatomical area of a multi-rooted tooth where the roots devide Tenacious – hard to remove Traction – a pulling force exerted on a skeletal structure (tooth) by means of a special device or apparatus
