Ultrasonic Scaling Flashcards
1
Q
Speed of piezoelectric
A
25000 - 50000 CPS
2
Q
What is the motion of piezoelectric vs magentoconstrictive
A
Linear vs elliptical motion
3
Q
Mechanism of action of scaler
A
Lavage (water flush off plaque) and cavitation (break up into tiny pieces)
4
Q
Depth of ultrasonic scaler
A
Can go up to 10mm
Hence better at reaching apical plaque zones garnot et al 2004
5
Q
Hand instrumentation vs ultrasonic to clean furcation
A
Ultrasonic better for furcation II and III sugaya et al 2002
