Which procedure smooths imperfections created by the scaling process?

• A. Polishing
• B. Probing
• C. Scaler
• D. Curette

Answer: (A)

The main idea here is that after scaling, the surface can have microscopic roughness and tiny irregularities. Polishing is the step that specifically smooths those imperfections. By using a polishing paste with a slow-speed instrument (often a rubber cup), it abrades the micro-rough spots left by scaling, resulting in a smooth, glaze-like surface. A smooth surface resists plaque adherence better and cleans more easily, which aids healing and long-term oral health.

Probing is a diagnostic process to measure pocket depths, so it doesn’t alter surface texture. A scaler or curette are instruments used to remove calculus and perform root planing; their primary purpose is material removal, and they can create or leave behind roughness if not used properly, rather than purposefully smoothing the surface.
