    Study Notes

    Isolation of the Operating Field

    • Isolation is used to maintain a controlled operating field
    • Moisture control is crucial (saliva, blood)
    • Accessibility and visibility to treat soft tissues (lips, cheeks, gingiva, tongue) are essential
    • Types of isolation include relative and absolute

    Types of Isolation

    • Relative Isolation: Protects the operating field from saliva only
    • Absolute Isolation (Rubber Dam): Protects the operating field from all fluids (saliva, blood, fluids, water vapor)

    Relative Isolation Instruments

    • Cotton rolls
    • Saliva ejectors
    • High-volume evacuators (exhaustors)
    • Cotton roll holders
    • Lip retractors

    Relative Isolation Indications

    • Temporary filling placement
    • Amalgam fillings
    • Glass ionomer cement (GIC) fillings
    • Cementation of crowns with GIC
    • Bleaching
    • Scaling
    • Other procedures

    Absolute Isolation Instruments

    • Rubber sheet
    • Rubber dam frame
    • Molar clamp
    • Pre-molar clamp
    • Front clamp
    • Clamp forceps
    • Hole punch
    • Other instruments
