Rubber Dam

# In Which dental procedure is a rubber dam most indicated?
A. Deep caries
B. Direct pulp capping
C. Indirect pulp capping
D. Preparing a crown

The correct answer is: B. Direct Pulp capping. 

In direct pulp capping, it is essential to have adequate access, visibility, and isolation of the operating field.

Direct pulp capping is indicated if a pin-point pulp exposure is made during cavity preparation.

Teeth should be properly isolated to avoid saliva and bacterial contamination during direct pulp caps.

Proper isolation of the operating field also allows proper sealing of the cavity of the tooth.
