What methods can be used to prevent aerosol generation during coronal polishing?

Preventing aerosol generation during coronal polishing is essential for minimizing the risk of airborne transmission of infectious agents. Using high-volume suction in conjunction with maintaining a proper distance from the mouth is an effective method for controlling aerosol production. High-volume suction can capture a significant portion of the droplets and aerosols created during the polishing process, thereby reducing the potential exposure for both the patient and dental personnel.

Maintaining a proper distance from the mouth aids in minimizing the spread of aerosols, as it ensures that the suction device can effectively draw in the particles before they disperse into the air. This combination of techniques—high-volume suction plus proper positioning—helps create a safer clinical environment.

Other methods may not be as effective in limiting aerosol generation. For example, a standard suction device may not provide the same level of efficiency as high-volume suction, and using only hand instruments may not be practical for coronal polishing, which typically involves a rotary instrument. Increased air pressure from the handpiece could actually contribute to aerosol spread, as it can create more turbulence and dispersion of particles into the air, thereby increasing potential contamination risks.
