|Primary Purpose of Infection Control||prevent the transmission of infectious disease|
|3 forms of Transmission|| From pt. to dental professional|
From dental professional to pt.
From pt. to pt.
|Pathogens in oral or respiratory secretions:|| Cold and flu viruses and bacteria|
Hep B and C
Herpes simplex virus
|General Routes of Transmission|| -Direct Contact with pathogens (in saliva, blood, resp. secretions, or lesions)|
-Indirect contract w/ contaminated objects or instruments
-Direct contact w/ airborne contaminates in spatter or aerosols
|What 3 things must be present in disease transmission|| 1. Susceptible host|
2. Pathogen w/ sifficient infectivity
3. Portal of entry where pathogen can enter host
(infection control alters 1 of these three)
|Protective Attire and Barriers|| Clothing: to prevent skin and mucous membrane exposure to body fluids (Changed daily or when soiled )|
Gloves: worn to prevent contact w/ blood, saliva or mucous membrane (Changed between pts. and can not be washed)
Mask and eyewear: wear when spatter and aerosolizes of blood and saliva are present (Change mask between pts or if they become soiled or wet; Eyewear must be cleansed between pts.)
|When do we wash our hands?||Before and after treating each pt. and after touching objects or surfaces contaminated by blood or saliva|
|Critical Items|| those that penetrate soft tissue or bone (forceps, scalpel, scalers, burs)|
*None in radiology
|Semicritical items|| those that contact, but do NOT penetrate soft tissue or bone.|
Ex: film holders, mirrors, amalgam condensors
|Non-critical Items|| those that do not come in contact w/ mucous membranes|
Ex: PID, exposure buttons, control panel, lead apron
|Before Exposure: Treatment Area||-Cover w/ plastic all areas that are most likely to be touched|
X-ray machine: tubehead, PID, control panel,exposure buttons
Dental chair: headrest, and chair adjustment controls
Work area: where x-ray supplies are placed during exposure
Lead apron: if contaminated it must be wiped w/ disinfectant between pts.
|Before Exposure: Supplies and Equipment|| All anticipated supplies and equipment must be prepared and sterilized|
Film: should be dispensed from a central supply area into a coin envelope, plastic cup or sandwich bag
Film holding-devices: should be sterilized
Misc: cotton rolls, paper rowels, cup labeled w/ pts. name
|Before Exposure: Patient Preparation||Chair Adjustment: position so that the pt. is seated upright. Adjust the height so that it is comfortable for radiographer.|
Headrest Adjustment: supporting head so that the pts. upper arch is parallel w/ floor
Lead Apron: place and secure before any exposure
Misc: remove any of the pts. belongings (glasses, gum, dentures, tongue and lip rings)
|Before Exposure: Dental Radiographer|| Handwashing: wash w/ soap so that pt. can see you, or verbalize it. |
Gloves: after washing, immediately put on gloves
Mask and Eyewear: no aerosols are created and so this is optional (CBC PROTOCOL IS TO WEAR THEM)
Film-holding Device: w/ gloved hands remove and assemble in front of pt.
|During Exposure||Once gloved try to only touch covered surfaces and minimize what you touch|
Drying of Exposed Film: dry w/ a paper towel to remove excess saliva
Collecting Exposed Films: place in a cup labeled w/ pts. name-Used to transport to darkroom (Do not touch w/ gloves)
Avoid scatter rad. by NOT placing them in the same room
Film Holding Devices: should go from covered working area to pts. mouth and back to covered working area
Interruptions During Exposure: when you leave the area you must take gloves off and wash, and then rewash and re-glove when returning.
|After Exposure||Dispose of Contaminated Items: while still wearing gloves throw away cotton rolls, bwx tabs, bags etc. Also dispose of all plastic covers|
Film-holding Devices: place film holder in designated area for contaminated instruments
Lead Apron: remove this once gloves have been removed
Surface Disinfectant: wipe any uncovered areas that were contaminated
|Handling Exposed Film (slide 1)|| -Bring cup from work area to darkroom|
-Place paper towel down in dark room
-Place cup next to towel
-Put on gloves
-Turn off lights and secure door
-Take 1 film out of cup
-Open packet and slide out film, lead, and black paper .
|Handling Exposed Film (slide 2)|| -Dispose of foil|
-Open black paper w/o touching the film and let film fall on the paper towel.
-Discard of black paper
-Once all film have been opened dispose of cup
-Remove gloves and wash hands
-Label a mount w/ pts. name and place films in once they are done processing.
