Which factor influences the rate of abrasion during polishing?

The amount of agent used during polishing directly influences the rate of abrasion. A larger quantity of polishing agent generally results in a more significant surface contact, increasing the effectiveness and efficiency of the polishing process. When sufficient polishing agent is applied, it provides enough material to create the necessary friction and abrasive action needed to remove stains and plaque from the surface of the tooth.

In contrast, using too little agent may reduce the polishing effectiveness, resulting in inadequate removal of deposits. This is why controlling the amount of polishing agent is critical for achieving optimal results during dental polishing procedures, ensuring that surfaces are adequately treated without causing unnecessary wear or damage.

The other factors, while they may influence polishing in various ways, do not have as direct an impact on the rate of abrasion as the amount of agent used. For instance, the color of the agent is not related to its abrasive properties, and the temperature may affect the viscosity but does not inherently accelerate abrasion. The type of plaque present can affect how easily it polishes away but does not dictate the actual rate at which abrasion occurs during the polishing process.
