Ultrasonic Scaling
Also called: Power scaling
Ultrasonic scaling uses high-frequency tip vibrations (25-50 kHz) combined with water irrigation to disrupt calculus, biofilm, and stains — delivered via piezoelectric or magnetostrictive handpieces.
What is ultrasonic scaling?
Ultrasonic scaling is the umbrella term for power-driven instrumentation that removes calculus, biofilm, and stain via a vibrating tip cooled by water irrigation. The two dominant technologies are piezoelectric and magnetostrictive, distinguished by the mechanism that drives the vibration.
Ultrasonic scaling is the workhorse of non-surgical periodontal therapy, supported by decades of clinical evidence showing outcomes equivalent to hand instrumentation with substantially less clinician fatigue and shorter appointment times.
When is it used?
Ultrasonic scaling is indicated for:
- Routine supragingival debridement
- Non-surgical periodontal therapy (subgingival debridement and root planing)
- Heavy calculus removal
- Endodontic and surgical access
