Which device provides isolation by placing a latex dam around the tooth?

• A. Rubber dam frame
• B. Rubber dam
• C. Round burs
• D. Clamp forceps

Answer: (B)

Isolating the tooth from saliva to keep the working area dry is achieved with a rubber dam. The latex sheet encircles the tooth, creating a barrier that protects the operative field, improves visibility, and reduces the risk of debris or irrigant entering the airway. The frame provides tension and support to keep the dam taut, while clamps and forceps are used to secure the dam around the tooth. Round burs, in contrast, are cutting instruments and do not provide isolation.
