    Study Notes

    Restorative Dentistry Pre-Clinical I: Instruments

    • Dental Mirror: Used for indirect vision, reflecting light to the operative field, and retracting soft tissues.

    • Dental Probe: Used for exploring surface texture, hardness, and depth, and assessing parallelism.

    • Landgraf Tweezers: Used for transferring items in and out of the patient's mouth.

    • Toothbrush: Used in the practice room to clean prepared cavities.

    • Dental Air-Water 3-Way Syringe: Used for washing, cleaning, and drying surfaces.

    • Black Excavator: Used for gently removing decayed dentin. A heated version is used to cut root canal filling (guttapercha).

    • Round/Ball Ended Burnisher: Used for condensing filling materials.

    • Williams Condenser: Used for condensing filling materials (originally for amalgam fillings).

    • Vajna Double Ended Burnisher: Used for condensing filling material and burnishing/shaping the surface, mostly used for amalgam fillings.

    • Heidemann Dental Spatula/Flags: Used for transporting filling material, placing retraction cords into the sulcus, condensing and shaping filling material, and placing/inverting the rubber dam.

    • Double Ended Dental Mixing Spatula: Used for mixing cements. The rounded end takes the powder, and the sharper end mixes the compounds (used to check the Christensen phenomenon).
