0.2-0.5 mm pulpal to D.E.J.
What leads to pulp exposure during cavity preparation?
Cutting across recessional lines of the pulp
What should be avoided to prevent exposure of more dentinal tubules to different types of irritation?
Over cutting of enamel
Why is it important to decrease the width of the cavity during cutting procedures?
To avoid exposure of more dentinal tubules to different types of irritation

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.
Test your knowledge of the biological fundamentals of cavity preparation, including the principles related to the preservation of tooth vitality, health, and investing structures. Topics covered include protection of dentin and pulp, control of caries, and safeguarding of investing tissues and adjacent teeth.
