Study Notes
Infection Control Certification Examination Key Points
- DHCP Acronym: Represents Dental Healthcare Personnel, indicating healthcare workers in a dental setting.
- Sterilization Definition: The process that eliminates all microorganisms, ensuring complete safety.
- Disposal of Contaminated Items: Items soaked with blood or saliva must be disposed of in a properly labeled leak-proof biohazard bag.
Cleaning and Disinfection Standards
- Clinical Contact Surfaces: Should be cleaned and disinfected with a Cal EPA registered, hospital-grade disinfectant that is either low-to-intermediate or intermediate level after each patient.
-
Types of Items:
- Semi-Critical Items: Instruments that contact oral mucous membranes but do not penetrate soft tissue or bone.
- Non-Critical Items: Items coming into contact with intact skin, requiring appropriate cleaning.
Definitions and Terms (Matching)
- Germicide: A chemical agent that can disinfect based on contamination levels.
- OPIM (Other Potentially Infectious Materials): Includes human body fluids like saliva, unfixed tissue, and blood.
- Cleaning: The physical removal of soil and debris from objects.
- Critical Items: Devices that penetrate soft tissue or bone.
- Sterilization Process: Involves time, heat, and pressure, commonly in a steam autoclave.
True/False Statements Essentials
- Heavy-Duty Gloves: Mandatory for DHCP to prevent puncture wounds during instrument processing.
- Gown Management: Reusable or disposable gowns must be changed after each patient.
- Operatory Cleaning: Requires cleaning and sterilization between patients, including barrier management.
- Operator Attire: Protective attire is essential whenever there's a risk of blood or aerosol exposure.
- Housekeeping Surface Cleaning: High-level disinfectants are not necessary; standard cleaning suffices.
Personal Protective Equipment (PPE) Guidelines
- PPE includes protective eyewear and attire, but NOT exam gloves when assisting in procedures.
Germicides and Their Categories
- Germicides categorized by their disinfection effectiveness: low-level, intermediate-level, high-level; rated on their ability to kill specific microorganisms.
Dental Procedure Protocol
- Impressions: Must be cleaned and disinfected with at least a low-to-intermediate disinfectant prior to lab manipulation.
- Standard Precautions: Apply to all patients, not just those with infectious diseases.
- Ultrasonic Cleaner: Should be covered to prevent droplet contamination.
Disinfection Process Effectiveness
- Low-level disinfectant is the least effective, killing some bacteria and viruses.
- Use alcohol-based hand rubs when hands are not visibly contaminated.
Sharps and Waterline Management
- Sharps Definition: Contaminated objects that can pierce the skin, including dental burs and needles.
- Flushing Protocol: Waterlines must be purged with air and flushed for at least three minutes daily and for one minute between patients.
Testing Sterilization Processes
- Heat indicator devices should test sterilization cycles weekly.
- Endospores are resistant to intermediate-level disinfectants.
Compliance and Regulations
- Follow CDC guidelines for universal precautions expanding to all diseases.
- Dispose of sharp items immediately in designated containers.
- Thorough cleaning and sterilization protocols required for all lab burs and rotary devices.
