Ultrasonic scaling

• Ultrasonic Scaling


  The use of high-frequency vibrations to remove plaque and calculus from teeth
• Rationale for Ultrasonic Scaling


  The reasons for using ultrasonic scaling
• Uses of Ultrasonic Scaling

  • Plaque and calculus (tartar) removal
  • Periodontal therapy
  • Stain removal
  • Orthodontic care
  • Implant maintenance
  • Pre-surgical cleaning
  • Debridement
• Rational for scaling: Efficiency and effectiveness


  • Ultrasonic scalers can remove plaque and calculus more quickly and efficiently compared to manual scalers
  • They use high-frequency vibrations that break down deposits with less physical effort and time
• Improved Access


  • The small tips can reach deeper into periodontal pockets and other hard-to-reach areas, providing a thorough clean
• Reduced patient comfort


  • Less physically demanding on the clinician and the patient
• Antibacterial Benefits


  • The ultrasonic vibrations can disrupt bacteria cells
  • The water spray can help to flush out bacteria and toxins from the periodontal pockets, providing a cleaner and more hygienic environment
• Minimally Invasive


  • Can be gentler on the tooth enamel and surrounding tissues, potentially reducing the risk of damage and irritation
• Speed


  • Cuts procedure time. This can enhance patient compliance
• Tip


  Use the HS and USS in conjunction
• Types of Ultrasonic Devices

  Cavitron<|>Piezo
• Cavitron


  • Uses magnetostrictive technology
  • Generates more heat, requiring a continuous flow of water to cool the tip and flush debris
  • Good for heavy calc build up
  • Can be less comfortable (due to elliptical motion)
  • All surfaces of the tip are active
• Piezo


  • Uses piezoelectrical technology
  • Generates less heat compared to the Cavitron, but water is still used for cooling
  • More comfortable, less heat and water, quieter
  • Not as effective for heavy calc build up
  • Pulverises calculus
  • Active sides of the tip are the lateral sides
