Scaling is known as scaling. When scaling is performed, instruments or sandblasting can form indentations on the enamel surface, resulting in increased roughness of the tooth surface. 1. Commonly used scaling techniques include hand instrument scaling, ultrasonic scaling, sandblasting, and hand scalers. Both ultrasonic scaler heads and sandblasting create small indentations on the surface of the teeth, causing the surface to become rough. Sandblasting causes less damage to the enamel than the first two. 2. These indentations may lead to the redeposition of plaque and pigment on the surface of the teeth, which may affect the long-term therapeutic effect. The smoothness of the tooth surface can be restored by polishing. It is recommended to visit a regular medical institution for professional treatment with the help of a doctor.
