    Study Notes

    Biologic Principles of Tooth Preparation

    • The primary consideration for biologic principles of tooth preparation is the preservation of pulp vitality and prevention of pulp injury.

    Causes of Pulp Injury

    • The following are potential causes of pulp injury during tooth preparation:
      • Heat generation
      • Pressure
      • Vibration
      • Desiccation
      • Chemical irritation
    • The following are NOT potential causes of pulp injury during tooth preparation:
      • Bacterial invasion
      • Microbial infection

    Prevention and Conservation

    • The main focus of prevention during tooth preparation is the protection of adjacent structures and conservation of tooth structure.
    • The preferred method for protection of adjacent structures is the use of a rubber dam or a protective strip.
    • The preferred material for protection of adjacent structures is a rubber dam.
    • The purpose of using the proximal enamel of the tooth being prepared is for protection of adjacent structures.

    Biologic Considerations

    • The main goal of biologic considerations during tooth preparation is to avoid pulp injury and preserve pulp vitality.
    • Biologic considerations primarily aim to avoid damage to the pulp and surrounding tissues.
    • The main focus of biologic considerations is the preservation of pulp vitality and prevention of pulp injury.

    Reference

    • The basic principles of tooth preparation are covered in Chapter [X] of Rosenstiel's book, pages [X-X].
