What is the proper speed for a handpiece during coronal polishing?

The proper speed for a handpiece during coronal polishing is typically between 10,000 to 20,000 RPM. This speed range is optimal as it allows for effective polishing without generating excessive heat that can damage the enamel or cause discomfort to the patient. At this speed, the polishing paste can effectively remove surface stains and debris while maintaining patient safety and comfort.

Using a faster speed, particularly above 20,000 RPM, increases the risk of overheating tooth surfaces, which can lead to pulp damage or sensitivity. Additionally, speeds that are too fast can compromise the control the dental professional has over the polishing process, potentially causing uneven polishing or difficulty in maneuvering the handpiece.

On the other hand, speeds lower than the recommended range, like 5,000 RPM, do not provide enough energy to effectively polish the surfaces, resulting in inadequate stain removal and a less effective cleaning procedure. A lack of specific speed requirements does not provide the guidance necessary to ensure the efficacy and safety of the coronal polishing procedure.

In summary, maintaining the handpiece speed within the 10,000 to 20,000 RPM range strikes the balance needed for effective and safe coronal polishing.
