Ultrasonic scaling has been around for decades and should be part of the dental hygienist’s daily patient routine. Sonic scalers are still around, but most have transitioned to ultrasonic scalers.

There are two types of ultrasonic scalers: magnetostrictive and piezoelectric. Both ultrasonics are effective but operate differently. Piezoelectric devices use electrical energy to activate crystals within the handpiece to vibrate to the instrument tip.1 Magnetostric devices transfer electrical energy to metal stacks made of nickel-iron alloy or to a ferrous rod to vibrate the insert.1

When using magnetostrictive technology, it is important to understand all sides of the tip are active. The lateral sides are most commonly used, but the face and back are also active. To compare, only th...
