What are layers of microorganisms that adhere to surfaces in dental settings referred to as?

The term commonly used to describe layers of microorganisms that adhere to surfaces in dental settings is "biofilm." Biofilm is a complex aggregation of microorganisms, primarily bacteria, that are embedded in a protective extracellular matrix. This slimy layer allows bacteria to adhere to various surfaces, such as dental equipment, instruments, or even teeth, making them much more resistant to removal and disinfection.

In dental settings, biofilms can form on medical instruments, inside water lines, and on the surfaces of teeth, leading to challenges in infection control and patient safety. Understanding biofilm formation is crucial for dental professionals to implement effective cleaning and sterilization protocols and to maintain a safe environment for both patients and staff.

Other terms might describe similar concepts, but they lack the specific definitions and implications associated with biofilm. For example, "pathogen layers" does not accurately capture the complexity of microbial communities within biofilms, nor do "microbial colonies" and "contaminant films," which are less precise in describing the structured nature of biofilms and their implications in infection control.
