Principles of Tooth Preparation

Tooth preparation is the mechanical or chemical treatment of dental disease or injury to hard tissue, restoring a tooth to its original form. It enables the tooth to hold restorative materials without causing mechanical or biological failure. The goal is now to minimize the amount of dentin involved in the preparation process.

Factors Influencing Tooth Preparation

The caries rate is being reduced by:
- Fluorides
- Nutritional counseling
- Oral hygiene programs
Cavity preparation principles (Black and Tylman) are evolving to accommodate new aesthetic and chemical techniques (e.g., acid etching and esthetic bonding)

Objectives of Tooth Preparation

Preserve tooth structure, reducing tooth reduction to a minimum.
Provide retention for the restoration.
Maintain an acceptable finish line to ensure resistance.
Perform minimal axial tooth reduction to encourage favorable tissue response.
Diagnosis and proper tooth preparation are critical for successful fixed prosthetics.

Principles Guiding Tooth Preparation

Mechanical: Retention & resistance form
Biological: Conservation of tooth structure, supragingival margins and harmonious occlusion.
Aesthetic: Minimum metal display in restorations, porcelain thickness and subgingival margins.

This quiz covers the fundamental principles of tooth preparation, focusing on the mechanical and chemical treatments necessary to restore dental health. It will explore factors influencing tooth preparation, such as caries prevention techniques and evolving cavity preparation principles. Test your understanding of how to preserve tooth structure while ensuring effective retention for restorations.
