Infection Control Chapter 15 Outline Infection Control and the Dental Radiographer Infection control basics Guidelines for infection control practices Infection control in dental radiography

Infection Control and the Dental Radiographer Infectious diseases present a significant hazard in the dental environment Infection control protocols are used in dentistry to minimize the potential for disease transmission

Rationale for Infection Control Haring (p. 163) To prevent the transmission of infectious diseases May be transmitted from Patient to dental professional Dental professional to patient Patient to patient

Pathogen A microorganism capable of causing disease
