Although there is no direct evidence indicating that dental radiographic procedures are a major cause of disease transmission, dental professionals cannot ignore infection control practices in dental radiology. Both digital and film-based radiography pose opportunities to cross-contaminate equipment and environmental surfaces with blood or saliva. The Centers for Disease Control and Prevention and the American Dental Association have addressed specific infection control practices to decrease the potential for cross-contamination in dental radiology and reduce the likelihood of disease transmission.

This basic-level course describes the CDC and ADA guidelines, recommendations, and procedures necessary to control cross-contamination and infection that is possible with dental radiography. This course provides dental professionals with information regarding the recommended infection control practices that can significantly reduce cross-contamination in dental radiology, thus protecting patients and practitioners alike. The course examines infection control procedures at different stages and in different settings of radiology, including film exposure, film processing, extraoral procedures, and during the use of digital radiography.
