![]() ![]() There are two main types of ultrasonic scalers: piezo and magnetostrictive.So, here are the most important things to remember about dental scalers: ![]() Between the 25kHz inserts and the 30kHz inserts, usually referred to as simply 25K or 30K, the 30K inserts are usually quieter. As stated above, tips from piezo scalers will not work in them. Most of these scalers require inserts that match their frequencies. Magnetostrictive scalers operate at either 25kHz or 30kHz. Dentsply’s well-known Cavitron is one example of a magnetostrictive ultrasonic scaler. These scalers generally vibrate in an elliptical motion, but again it is important to mention that the shape of the insert can change the shape of the motion during vibration. These types of scalers use a stack of nickel alloy strips in the end of the insert itself to vibrate the insert. Magnetostrictive scalers have been around for many years and use inserts instead of tips, though the two are similar. However, because they do not generate as much heat, the colder water irrigation they produce may cause discomfort to patients with teeth that are sensitive to cold. ![]() The quartz crystal in piezo scalers does not generate a lot of heat during operation, so these types of scalers require less water irrigation. Inserts for magnetostrictive scalers will not work in piezo scalers. Most piezo scalers require tips that are custom-designed for each brand. But when operated correctly, these scalers are generally considered to be gentler on teeth than magnetostrictive scalers. This linear motion means that Piezo scalers can be more technique-sensitive, since the scaler needs to stay parallel to each tooth’s surface to avoid damaging the tooth with the scaler tip. Piezo scalers generally operate at a frequency of around 32 to 35 kHz but some operate at even higher frequenciesĬonsensus among dental professionals is that piezo tips tend to rotate in a linear motion during ultrasonic vibration, though the design of the tip itself can affect this motion. The number of times each tip vibrates per second is called the scaler’s frequency. 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. The Two Ultrasonic Scaler Choicesĭental ultrasonic scalers come in two different varieties: piezo and magnetostrictive. What are the differences between those options? If you have ever wondered, read on to find out. Dental professionals are presented with a wide range of dental scaling options. ![]()
