What is a common method used by RDH to remove plaque and stains?

The use of polishing cups and paste is a standard method employed by registered dental hygienists (RDHs) to effectively remove plaque and stains from the surfaces of teeth. This technique involves using a revolving cup that holds a specially formulated abrasive paste designed to safely polish tooth enamel. The action of the polishing cup, combined with the abrasive qualities of the paste, allows for the removal of extrinsic stains and plaque, resulting in a smoother and cleaner surface.

This method is particularly effective because it not only removes superficial stains but also contributes to the prevention of future plaque accumulation by creating a smoother tooth surface. The polishing procedure is typically performed after scaling and has aesthetic benefits, giving patients a noticeable improvement in the appearance of their teeth.

In contrast, the other options provided serve different purposes in dental hygiene. High-speed handpieces are primarily used for cutting and preparing teeth for restorative procedures rather than for cleaning. Scalers are designed to remove calculus and plaque from tooth surfaces, but they do not polish or smooth the enamel as polishing cups do. While dental sealants play a crucial role in preventing decay by sealing pits and fissures on chewing surfaces, they are not involved in the removal of plaque or stains.
