What are two types of ultrasonic scaler’s
Magnetostrictive ultrasonic scaler and Piezoelectric ultrasonic scaler
What are the two types of scalars available
Ultrasonic scaler’s, sonic scalars
Describe ultrasonic scaler’s
Most commonly used in Veterinary practice. Driven by an electric micromotor. Can cause cavitation and implosion of water to help disrupt the calculus
Describe a magnetostrictive ultrasonic scaler
Tip vibration generated by magnetostrictive mechanism
Describe a piezoelectric ultrasonic scaler
Tip vibration generated by piezoelectric mechanism in hand piece.
Describe sonic scalers
Air driven
Tip vibrates at sonic frequencies
What are the two pieces to the magnetostrictive ultrasonic cleaner
The tip and the stack
Describe how you use the magnetostrictive ultrasonic cleaner
Light sweeping strokes using a modified pencil grip across a tooth surface
What happens if the stack or tip is inefficient
Thermal damage to teeth
Can the stack and tip be placed in the ultrasonic cleaner
No. It is okay to autoclave the stack and the tip though
What is a sonic scaler used for
Supragingival scaling
What is the maximum amount of time when using a scaler on teeth
Three consecutive seconds
At what point should you replace the tip
When it is 2 mm down
What water can be used with a mechanical scaler
Distilled or filter water
What is the sharp tip manual scaler usd for
Supragingival use
