  1. Infection Control DHYG 116 Oral Radiology I

  2. Objectives • Chapter 15 reading: Haring (pp. 162-173) • Define the chapter keywords • Discuss the rationale for infection control • List 3 possible routes of transmission • Discuss infection control procedures: handwashing, barriers, sterilization / disinfection • Describe infection control procedures before, during and after x-ray exposure & processing • Discuss film handling with and without barrier envelopes

  3. Infection Control • Questions • What is the rationale for infection control? • What infection control procedures are necessary before, during, and after x-ray exposure? • What infection control procedures are necessary for processing?

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

  5. 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

  6. 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

  7. Pathogen • A microorganism capable of causing disease

  8. Infection Control Terminology • Haring (pp. 163-164) • Antiseptic • Asepsis • Bloodborne pathogen • Disinfect • Disinfection • Exposure incident

  9. Infection Control Terminology • Infectious waste • Occupational exposure • Parenteral exposure • Sharp • Sterilize • Sterilization • Universal precautions

  10. Guidelines for Infection Control Practices • Haring (p. 164) (Box 15-1) • Protective Attire and Barrier Techniques • Handwashing and Care of Hands • Sterilization and Disinfection of Instruments • Cleaning and Disinfection of Dental Unit and Environmental Surfaces

  11. Protective Attire and Barrier Techniques • Haring (pp. 164-165) • Protective clothing • Gloves • Masks • Protective eyewear What’s missing?

  13. Sterilization and Disinfection of Instruments • Haring (p. 165) • Critical instruments • Semicritical instruments • Noncritical instruments

  14. Cleaning and Disinfection of Dental Unit and Environmental Surfaces • Haring (p. 165) • Intermediate-level disinfectants • Low-level disinfectants

Infection Control in Dental Radiography • Haring (pp. 165-166, 168) (Table 15-1) (Box 15-2) • Infection Control Procedures Used Before Exposure • Infection Control Procedures Used During Exposure • Infection Control Procedures Used After Exposure • Infection Control Procedures Used for Processing

  16. Infection Control Procedures Used Before Exposure • Haring (pp. 166-167) • Preparation of the treatment area • X-ray machine • Dental chair • Work area • Lead apron

  17. Infection Control Procedures Used Before Exposure • Haring (p. 167) (Fig. 15-1) • Preparation of supplies and equipment • Film • Film-holding devices • Miscellaneous items

  18. Infection Control Procedures Used Before Exposure • Preparation of the patient • Chair adjustment • Headrest adjustment • Lead apron • Miscellaneous objects

  19. Infection Control Procedures Used Before Exposure • Preparation of the dental radiographer • Handwashing • Gloves • Mask and eyewear • Film-holding devices

  20. Infection Control Procedures Used During Exposure • Haring (pp. 167-168) • Drying of exposed films • Collection of exposed films • Film-holding devices • Interruptions during exposure

  21. Infection Control Procedures Used After Exposure • Haring (pp. 168-169) • Disposal of contaminated items • Film-holding devices • Handwashing • Lead apron removal • Surface disinfection

  22. Infection Control Procedures Used for Processing • Haring (pp. 169-170) (Figs. 15-2, 15-3) • Film transport • Darkroom supplies • Film handling with barrier envelopes • Film handing without barrier envelopes • Disinfection of darkroom • Daylight loader procedures – in lab
