Which tool is specifically used to remove stains from deep pits and fissures on enamel surfaces?

1. Polishing cups

2. Bristle brushes

3. Rubber cups

4. Floss

The correct answer is: Bristle brushes

The tool specifically used to remove stains from deep pits and fissures on enamel surfaces is a bristle brush. Bristle brushes have stiff, tightly packed bristles that can effectively reach into the irregularities of the enamel surface, including the deep grooves and pits, where stains can accumulate. Their design allows for the mechanical action necessary to dislodge debris, plaque, and stains that may become trapped in these difficult-to-access areas. In contrast, polishing cups and rubber cups are primarily designed for smoothing and polishing the surface of teeth, rather than for stain removal from deep recesses. While they can help in polishing once the surface is cleaned, they are not as effective at dislodging stains embedded in pits and fissures. Floss is intended for cleaning between teeth and does not have the capability to address stains on the enamel surfaces in the same way that a bristle brush does. Understanding the specific applications of these tools is crucial for performing effective coronal polishing and maintaining dental health.
