What is the majority component of the spray produced by dental handpieces?

The majority component of the spray produced by dental handpieces is spatter. During dental procedures, high-speed handpieces create a combination of particles that include water, debris, and microorganisms. Spatter refers specifically to the larger droplets that are projected directly from the handpiece due to the force of the dental procedure, often falling onto surfaces in the immediate area.

Spatter is a significant concern for infection control because it can carry pathogens and contaminate the surrounding environment. Understanding this helps dental professionals implement appropriate infection control measures and maintain a safe treatment area. While aerosol, vapor, and spray mist also contribute to the overall particles produced by dental handpieces, spatter represents those larger droplets that have a more significant impact on surfaces and the clinician’s immediate environment.
