Which tool is commonly used to create openings in a tooth for decay removal?

• A. Calcium hydroxide applicator
• B. Clamp forceps
• C. Round burs
• D. Rubber dam punch

Answer: (C)

The ability to access and remove decay depends on using a cutting tool that can remove soft carious dentin and shape a clear opening without damaging surrounding walls. A round bur fits this job best because its spherical cutting tip efficiently removes decayed tissue and allows gradual widening of the access cavity. The rounded surface helps keep the margins smooth and reduces the risk of unnecessary gouging, giving a controlled pathway to reach the decay. The other tools aren’t for cutting tooth tissue: a calcium hydroxide applicator is used to place medicament, not to cut; clamp forceps are for handling rubber dam clamps; and a rubber dam punch is used to make holes in the dam, not to create an opening in the tooth itself.
