What area must be disinfected or covered prior to dental radiography?

The dental chair must be disinfected or covered prior to dental radiography because it is a frequently touched surface that can harbor pathogens. During dental procedures, the chair comes into contact with various bodily fluids, including saliva and blood, which can pose a risk of cross-contamination. By disinfecting the chair or using barriers, dental professionals can minimize the chance of transmitting infections between patients. This step is part of standard infection control protocols, ensuring that the environment is safe for both patients and staff during radiographic procedures. Proper disinfection practices help maintain a high standard of cleanliness and safety in the dental office, which is essential for effective infection control.
