    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.
