Dental Ultrasonic Scaler FAQ

Here are some common questions about dental ultrasonic scalers. Feel free to reply with questions or answers of your own.


Q: What is the difference between magnetostrictive ultrasonic scalers and piezo ultrasonic scalers?

A:  Magnetostrictive scalers use a stack of nickel alloy strips in the end of the insert itself to vibrate the insert. These scalers vibrate their inserts at either 25kHz or 30kHz. Cavitrons are part of this category.

Piezo scalers are the most recent development in dental ultrasonic scaling technology and use stacks of ceramic discs inside the scaler handpiece to vibrate the handpiece’s tip. Piezo scalers generally operate at a frequency of around 32 to 35 kHz but some operate at even higher frequencies.

For a more detailed explanation, check out our blog post on this topic.


Q: Are 25K and 30K scaler inserts interchangeable?

A: Unfortunately no. The size of scaler handpieces is different depending on the frequency. A 25K insert will not vibrate correctly into a 30K handpiece, and vice versa.


Q: Do I really need to install a water filter in my Cavitron?

A: It is highly recommended that you do. This will ensure that harmful materials in the water are not circulated through your scaler’s water line and shorten its lifespan.


Q: Is it normal for water to continue to flow out of Cavitron scalers for a short time even after the foot pedal is released?

A: Yes. This is normal operation.


Q: Can a malfunctioning flow regulator be cleaned out? Does it need to be calibrated by a dental technician?

A: The flow regulator is not something that needs to be cleaned. Instead, you will need to have it adjusted or replaced. You may need the assistance of a dental tech to check the status of the regulator, but the regulator does not need to be "calibrated." If it is misaligned it will simply need to be readjusted, if it is worn you will need to replace it.
