Study Notes
Infection Control in Dental Environment
- Emphasis on PPE guidelines predating the COVID-19 pandemic with an upcoming session on current protocols.
- Cross-contamination risks include:
- Direct: Person A to Person B
- Indirect: Person A to Object to Person B
- Aerosol-generating procedures pose a high risk for respiratory transmission from the respiratory tract.
Standard Precautions
- Universal precautions recommend treating all patients as potentially infectious.
- Key components include:
- Medical history assessment for each patient
- Vaccinations against MMR, Hepatitis A & B, Influenza, Pneumococcal, Varicella, Meningococcal, and COVID-19.
Personal Protective Equipment (PPE)
- Daily clinical scrubs recommended; do not wear over street clothes.
- Overcoats must be solid, closed-front with no pockets, fitting closely around wrists and neck.
Masks and Face Protection
- Masks protect against droplet transmission from saliva and blood.
- Change masks for each patient or if contaminated; they must be worn during all clinical activities.
- Face shields are necessary for procedures generating aerosols (e.g., fast handpieces, ultrasonic scaling).
Protective Eyewear
- Compulsory for all dental staff and patients, shields eyes from infectious materials and flying debris.
- Eye wash stations must be available for emergencies with sterile/distilled water; do not use tap water.
Hand Hygiene Practices
- Essential to reduce bacteria and prevent cross-contamination.
- Use antimicrobial soap (e.g., Hibiscrub) and avoid bar soap.
- Protocols include:
- Routine washing: water and non-antimicrobial soap
- Antiseptic washing: water and antimicrobial soap
- Antiseptic hand rub: 60%-95% alcohol-based rub
Nail and Towel Protocol
- Keep nails short, free from varnish, and avoid jewelry.
- Only disposable paper towels allowed; do not use cloth towels.
Glove Use
- Types include latex, vinyl, utility, and over gloves.
- Change gloves after each patient or if they are damaged during a procedure.
- Proper gloving techniques include washing hands before putting on gloves and ensuring gloves cover cuff of uniform.
Summary of Procedures
- Handwashing involves a minimum of 15 seconds before and after patient contact, focusing on thorough cleaning.
- Use of over gloves for unnecessary touchpoints (e.g., writing) to avoid contaminating clinical gloves.
