Study Notes
Infection Control Basics
- For infection to occur, the presence of an acceptable barrier is essential.
- Microbial aerosols, which are pathogens present in blood, do not cause disease in humans.
Chain of Infection
- Breaking the chain of infection involves avoiding contact with contaminated objects or instruments.
Personal Protective Equipment (PPE)
- Protective clothing should be frequently laundered; however, weekly laundering is not mandatory.
- Acceptable protective eyewear for dental radiographers excludes contact lenses.
Equipment and Workflow
- Daylight loader attachments on automatic processors are not meant for time-saving shortcuts; they must be used correctly for safety.
- It is unauthorized to wear rings under gloves, as this increases the risk of contamination.
Gloves Protocol
- Gloves should not be washed with soap during treatment interruptions; they should be changed to prevent cross-contamination.
Sterilization and Disinfection
- Disinfection does not eliminate spores; thus, sterilization processes are required for complete pathogen removal.
- Classification of semicritical objects refers to those that can penetrate soft tissue or bone, contrary to false statements.
Mouth Rinses and Infection Control
- Preprocedural mouth rinses, while often seen as optional, can help reduce the spread of infections, although evidence may vary.
Body Fluids and Infection Control
- Sweat is the only body fluid not subjected to standard infection control procedures.
- Handwashing is essential before, during, and after radiographic procedures.
Cleaning and Disinfecting Radiographic Areas
- Heavy-duty utility gloves are recommended for cleaning and disinfecting equipment and operatories.
- Indirect PSP plates and direct digital sensors require cleaning, disinfection, and covering with a plastic barrier for effective infection control.
Object Classification
- Lead aprons are categorized as noncritical objects in terms of infection control protocols.
- After patient treatment, reusable image receptor holding devices must always be sterilized.
Infection Control in Radiographic Procedures
- Image receptor holders are considered semicritical objects and require adherence to strict infection control protocols.
- Film packets with protective barriers are particularly beneficial when using daylight loaders to maintain cleanliness.
- After removing aseptic barriers, film packets may be processed with clean, dry hands as they remain uncontaminated.
