What is the purpose of the jaws of a dental clamp?

The jaws of a dental clamp are designed primarily to provide stability. When placed around a tooth, they securely hold the dental dam in position, preventing it from moving during the dental procedure. This stability is crucial for keeping the working area isolated from saliva and moisture, which allows for a dry environment essential for effective dental work.

The other options do not accurately represent the function of the clamp. Suction is not created by the jaws of a clamp; rather, it is typically facilitated by suction devices used in conjunction with dental procedures. The clamp is not intended to puncture the dam; instead, it might be positioned over a pre-punctured dam for proper placement. Additionally, cutting the dam is not a function of the clamp; a separate tool, such as scissors, would be used for that purpose. Thus, the primary role of the clamp's jaws in maintaining stability is vital to the overall success of the dental treatment.
