To make your scaling procedures as efficient and effective as they can be, it is important to understand the difference between different types of dental scalers and know what features to look out for. This includes knowing the difference between hand scaler designs, between sonic and ultrasonic devices and between magnetostrictive and piezoelectric devices.
Dental scalers are one of the most widely used instruments in dentistry. They are used primarily for removing plaque (calculus and tartar) and other deposits from the teeth, both above and below the gum line. The three types of scalers used in modern dentistry are hand scalers, sonic scalers and ultrasonic scalers.
Hand Scalers
Hand scaling is the most traditional method of removing plaque. Stainless-steel hand scalers are comprised of a handle and a tip. The tip is made up of a shank (upper and terminal) and a working end/blade. Most scalers now have tips at both ends of the handle.
Hand scalers with curved working ends are known as sickle scalers and are designed to be used on both anterior and posterior teeth. Scalers with no bend are known as straight scalers and are designed to be used on anterior teeth only.
Scaler tips come in several different designs for removing different levels of plaque. Thicker tips are more efficiency at removing heavier deposits while thinner tips are ideal for accessing difficult areas and tight tissues.
Most widely used hand scalers:
- H6/H7 Scaler - popular double-ended sickle scaler for use in the anterior, interproximal and premolar areas.
- 204 Scaler - sickle scaler for use in the posterior areas.
- M23 Scaler – universal scaler designed for interproximal access of anterior and posterior teeth.
