What should be done right before the exposure of radiographs?

Washing hands right before the exposure of radiographs is an essential practice in infection control. This step helps to prevent the transmission of pathogens and maintains a sterile environment during the radiographic process. Hand hygiene is a critical component of infection control protocols in any healthcare setting, including dental practices, as it reduces the risk of cross-contamination not only to the patient but also to the dental radiographer and other staff members.

While preparation of film packets, taking a medical history, and seating the patient comfortably are important steps in the radiographic process, they do not directly contribute to minimizing the risk of infection at the moment right before exposure. Proper handwashing ensures that any potential infectious materials are eliminated, thereby maintaining a safe environment for both the dental professional and the patient during the procedure.
