A dental scaler is an instrument used to remove plaque and calculus from the surfaces of teeth during professional cleanings.
Dental scalers can be classified according to their mode of action:
- Manual scalers, which are hand instruments held like pens to clean the teeth. These include Sickle Scalers, Anterior Jacquette and Posterior Jacquette scalers.
- Ultrasonic scalers, which are powered devices that use tips that move at an ultrasonic frequency ranging from 20-45 Khz to clean.
