    Study Notes

    Isolation and Moisture Control

    • This presentation covers isolation and moisture control in clinical dental practice.
    • The GDC learning outcomes emphasize taking responsibility for best practice guidelines and advising on appropriate preventive materials and treatments.
    • Objectives include explaining the necessity of moisture control, describing available methods, selecting appropriate techniques for patients, listing rubber dam indications/advantages/disadvantages, describing rubber dam placement methods, and practicing moisture control techniques on fellow students.

    Why is Moisture Control Necessary?

    • Saliva, blood, and crevicular fluid interfere with restorative material placement, leading to restoration failure.
    • Moisture negatively impacts the quality of procedures and visibility. Maintaining a dry field enhances dental procedures.
    • Modern procedures, like some involving SARS-CoV-2 prevention, are improved by a dry field.

    Sources of Moisture

    • Saliva
    • Blood
    • GCF (Gingival Crevicular Fluid)
    • Dental instruments
    • Dental materials

    Methods Used for Moisture Control

    • Aspiration (high volume suction for handpieces and ultrasonic scalers)
    • Compressed air
    • Absorbent materials (cotton rolls, dry guards, DryDent Sublinguals)
    • Retraction cord
    • Rubber dam

    Aspiration

    • High-volume suction is used with handpieces and ultrasonic scalers, efficient for preventing SARS-CoV-2 transmission.
    • Low-volume suction (saliva ejector) is used for smaller volumes of fluid or saliva.

    Compressed Air

    • A 3-in-1 tip jet blows moisture from cavities and tooth surfaces.
    • Can also be used to keep water off the mouth mirror.
    • Use with high-volume suction during a pandemic to prevent aerosols.

    Absorbent Materials

    • Cotton rolls absorb saliva.
    • Can be used for retraction of soft tissues like lips or tongue.
    • Soak cotton in water when removing to avoid mucosa damage.
    • Dry guards are flat pads of highly absorbent material over parotid ducts, useful for fissure sealants.

    Retraction Cord

    • Used for crown preparations, especially near gingival margins.
    • Often impregnated with haemostatic medication.
    • Helps stop bleeding and crevicular fluid oozing.

    Rubber Dam

    • A thin barrier sheet (latex or nitrile rubber) isolates teeth.
    • Allows access to specific teeth and is an efficient moisture control method.
    • Can be placed in 2 minutes by an efficient team.

    Why Use a Rubber Dam?

    • Protects the patient's airway.
    • Provides patient physical and psychological comfort.
    • Improves operator vision.
    • Retracts soft tissues.
    • Controls moisture.
    • Protects the operator from SARS-CoV-2.

    Indications for Use

    • When the patient is cooperative and informed.
    • If the patient has a clear nasal airway.
    • After administering analgesia.
    • When there's a risk of inhaling instruments or material fragments.
    • When using saliva-sensitive materials.
    • For adhesive restorations, complex restorations, root canal therapy, pulp capping, pulpotomy, and fissure sealants.

    Advantages of Rubber Dam

    • Complete isolation
    • Visibility
    • Prevents inhalation
    • Protection for staff
    • Reduces time
    • Reduces mouth breathing
    • Psychological comfort

    Disadvantages of Rubber Dam

    • Difficult communication
    • Patient tolerance
    • Jaw stiffness
    • Excessive dryness
    • Latex allergy
    • Time and skill required
    • Local anaesthetic (LA) needed
    • Suitability for clamp
    • Gingival trauma
    • Checking occlusion

    Rubber Dam Equipment

    • Rubber dam sheet
    • Stamp/Template
    • Frame
    • Punch
    • Applicator
    • Clamps
    • Scissors
    • Wedjets
    • Gauze
    • Dental floss
    • Caulking agent (Oraseal)

    Parts of a Rubber Dam Clamp

    • A detailed description of the parts of a rubber dam clamp (e.g., central arm, anterior arm, bow, beaks, contact points, notch).
    • Importance of proper four-point contact.

    Place Floss on Clamp

    • Procedure for placing dental floss on a clamp.
    • Importance of safety and preventing accidental inhalation.

    Mark Up and Punch Rubber Dam Holes

    • Procedure for marking and punching holes in the rubber dam.
    • Use of rubber dam templates.
