Why are barriers used on certain dental surfaces?

The use of barriers on certain dental surfaces is primarily due to the fact that some surfaces are difficult to disinfect or clean effectively. In a clinical setting, surfaces that are frequently touched or may come into contact with contaminants, such as countertops, dental chairs, and equipment controls, must be maintained in a sterile condition to ensure patient safety and compliance with infection control protocols.

When these surfaces are covered with barriers, it simplifies the process of maintaining cleanliness and hygiene. Barriers can be easily replaced between patients, which helps to minimize the risk of cross-contamination and the spread of infectious agents. This is particularly important in dentistry, where the potential for blood and saliva exposure exists. Using barriers reduces the time and labor required for thorough cleaning and disinfection, allowing dental professionals to focus on patient care while still adhering to safe and effective infection control measures.
