Study Notes
Cavity Preparation and Pulp Protection
- The routine depth of the cavity should be 0.2 mm to 0.5 mm to prevent mechanical irritation to the pulp.
Risks of Cavity Preparation
- Pulp exposure can occur during cavity preparation due to removal of excessive tooth structure or creation of a cavity that is too deep.
Prevention of Dentinal Tubule Exposure
- It is essential to avoid over-cutting of dentin during cavity preparation to prevent exposure of more dentinal tubules to different types of irritation.
Importance of Cavity Width Control
- Decreasing the width of the cavity during cutting procedures is crucial to prevent excessive tooth structure removal and minimize the risk of pulp exposure.
- Avoiding over-cutting of dentin during cavity preparation is important to prevent pulp exposure and maintain tooth vitality.
