    Study Notes

    Tooth Numbering Systems

    • Palmer Notation System uses a diagram with 8 quadrants, each with 8 teeth numbered 1-8 starting from the midline.
    • International Number System uses two digits, the first indicating the quadrant (UR: 1, UL: 2, LR: 3, LL: 4) and the second indicating the tooth number (1-8).
    • Universal Numbering System uses a single digit, 1-32 for permanent teeth and 1-20 for primary teeth, with the letter "d" preceding the number for primary teeth.

    Tooth Anatomy

    • Crown: The visible part of the tooth above the gum line.
    • Neck: The constricted area between the crown and the root.
    • Root: The part of the tooth embedded in the jawbone.

    Tooth Tissues

    • Enamel: The hardest tissue in the body, covering the crown.
    • Dentin: The main bulk of the tooth, located beneath enamel.
    • Cementum: A bone-like tissue covering the root.
    • Pulp: Soft tissue containing blood vessels, nerves, and lymphatics.

    Tooth Surfaces

    • Labial/Buccal: The surface facing the lips or cheeks.
    • Palatal/Lingual: The surface facing the palate or tongue.
    • Mesial: The surface facing the midline of the mouth.
    • Distal: The surface facing away from the midline of the mouth.
    • Incisal (Anterior): The biting edge of anterior teeth.
    • Occlusal (Posterior): The chewing surface of posterior teeth.

    Line Angles

    • Formed by the meeting of two surfaces.
    • Anterior teeth have 6 line angles.
    • Posterior teeth have 8 line angles.

    Point Angles

    • Formed by the meeting of three surfaces.
    • Anterior teeth have 4 point angles.
    • Posterior teeth have 4 point angles.

    Division Into Thirds

    • Incisal/Occlusal
    • Middle
    • Cervical
    • Apical
    • Mesial/Buccal/Lingual/Distal
