Initial preparation may remove all caries so the caries removal step can be skipped.

• A. False
• B. Not specified
• C. True
• D. Both

Answer: (C)

In amalgam cavity preparation, the bulk of decay is removed during the initial excavation. If that stage leaves no soft or suspect dentin and the remaining dentin is firm and caries-free, there is nothing left to remove, so a separate caries removal step isn’t necessary. This relies on confirming that all decayed tissue has been eliminated and that the cavity walls and floors are sound before proceeding with restoration. However, always verify carefully—if any dentin is soft, discolored, or there’s doubt about hidden decay, continue with caries removal rather than skipping it.
