Study Notes

Infection Prevention and Control in Dental Practices

Infection Prevention and Control (IPC) in Dentistry: IPC is crucial to prevent the spread of infectious diseases in dental settings.
Microorganism Transmission: Microorganisms can spread through direct contact, indirect contact (through instruments, equipment, contaminated surfaces), and airborne transmission (inhalation of infectious particles).
Hand Hygiene:
- Bare Below the Elbows: Dental professionals should have bare hands and forearms, removing all jewelry.
- Handwashing: Frequent and thorough handwashing is crucial. Paper towels are preferred for drying hands over hot air dryers.
- Alcohol-based Hand Rub (ABHR): ABHR can be used in specific situations as an alternative to handwashing.
- Rings: Rings should be removed before gloving, as they can hinder proper handwashing and increase the risk of microbial growth.
Personal Protective Equipment (PPE)
- Gloves: Wear appropriate clean gloves for each patient.
- Masks: Wear a mask that filters out airborne droplets.
- Eye Protection: Use protective eyewear to prevent eye contamination.
- Protective Clothing: Wear a clean lab coat or gown.
- Footwear: Wear a closed-toe shoe to prevent foot contamination.
Instrument Reprocessing:
- Categories of Instruments: Classify instruments based on their level of risk (critical, semi-critical, non-critical).
- Reprocessing Area: Have a designated area for cleaning and sterilizing instruments, with proper workflow.
- Cleaning: Clean instruments thoroughly through pre-cleaning, rinsing, and mechanical or manual cleaning.
- Sterilization: Sterilize instruments using appropriate methods (e.g., steam sterilization, dry heat sterilization) to eliminate all microorganisms.
Environment:
- Cleanliness: Maintain a clean and disinfected clinical environment.
- Surface Contamination: Regularly decontaminate all surfaces to prevent microbial growth.
Exposure Proneness Procedures:
- Exposure Proneness Procedures (EPP): Procedures such as oral surgery and endodontic procedures, where the patient’s open tissues are exposed to the clinician's hands.
- Blood-borne Virus Transmission: High-risk procedures require extensive attention to IPC to minimize the risk of blood-borne virus (HBV, HCV, HIV) transmission.
Committee Expertise: The ADA's guidelines are developed by a committee comprised of registered dentists, dental specialists, and non-dentists with expertise in IPC. They represent the dental profession on various national committees, including the NHMRC and CDNA.
Document Review: The guidelines are reviewed and endorsed by various organizations, including the Australian Health Protection Principal Committee (AHPPC) and the Dental Board of Australia.
Resource Recognition: The ADA's guidelines are recognized as a key resource for infection prevention and control in dental practice and are referenced by other organizations, including the NHMRC and the New Zealand Dental Council.
