Radiology Infection Control Infection Control • Rationale: – Purpose is to prevent the transmission of infectious disease – Infectious diseases may be transmitted from a patient to the dental professional – From the dental professional to a patient – From one patient to another patient Equipment of Infection Control • PPE • Hand Washing • Sterilization and Disinfection of Instruments – Critical instruments • Instruments used to penetrate soft tissue or bone – Semi critical instruments • Instruments that contact but do not penetrate soft tissue or bone – Noncritical instruments • Instruments or devices that do not come in contact with mucous membranes Before Exposure • Treatment area should be properly disinfected before x-rays – – – – X-ray machine Dental chair Work area Lead apron • Supplies and equipment – Film or digital sensors – Beam alignment devices – Miscellaneous items • Labeled Cup, cotton rolls and paper towels Before Exposure • Prep of the patient – – – – Chair adjustment Headrest adjustment Lead apron Miscellaneous Objects • Prep of the Operator – – – – Handwashing Gloves Mask and eyewear Beam alignment devices During Exposure • • • • Touch as few surfaces as possible Drying of film Place film in labeled cup Beam alignment devices should be placed on covered surfaces and replaced as used • Interruptions – Remove gloves and wash hands/then rewash and reglove After Exposure • While gloved – Dispose of contaminated disposable items – Remove gloves and wash hands – Remove lead aprons – Dismiss your patient • Reglove and remove all used equipment in operatory • Clean operatory as normal Processing X-rays • Film transport – Transported by cup • Darkroom supplies – Use paper towels and gloves – Film mounts/pencil for labeling • Film handling – Use gloves and place contaminated items on a paper towel before disposing properly • Disinfection of the darkroom – Areas touched by contaminated gloves must be wiped down Steps in developing an x-ray Use of a Daylight Loader • Place paper cup and the vinyl or non-powdered gloves in the daylight loader • Place the container with contaminated films next to the cup • Close the daylight loader lid, and push hands through openings • Put on gloves • Take one contaminated film out of the container • Load film to develop • Dispose of film wrappings in the paper cup • After developing remove gloves and place in cup • Remove hands from daylight loader • Wash hands • Lift lid to remove and discard cup • Label the film mount with patients name Daylight Loader
