Which substance is commonly used to enhance the polishing process?

All of the substances listed play a role in enhancing the polishing process in dental hygiene. Calcium carbonate is often used in polishing pastes due to its abrasiveness and ability to effectively remove debris and surface stains from teeth. Silica gel, with its fine particles, serves as a gentle abrasive that helps polish tooth surfaces without causing damage to enamel. Aluminum oxide is another common polishing agent that is quite effective in creating a smooth finish due to its hardness and ability to produce a fine polish.

Using these substances in combination can optimize the polishing process, as each material contributes unique qualities that improve the overall effectiveness and efficiency of tooth polishing procedures. Therefore, recognizing that all these substances are utilized for coronal polishing helps to understand their individual and collective importance in achieving optimal results during dental cleanings.
