What characterizes an 'A' clamp used in dental procedures?

An 'A' clamp is characterized by jaws that bend sharply down toward the tissues. This design allows for better access and visibility when working in specific areas of the mouth, particularly around the gingival tissue during various dental procedures. The shape enables the practitioner to manipulate the clamp easily and securely without impeding other structures within the oral cavity. The angled jaws facilitate a more secure grip on the tissues, which is crucial for tasks that may involve retraction or stabilization.

In contrast, the other options describe features that do not align with the purpose or design of an 'A' clamp. Jaws that are straight would lack the necessary angle for effective use in tighter spaces of the mouth, while jaws with rounded tips are typically associated with different clamps designed for different purposes. Similarly, jaws designed for anterior teeth only are not characteristic of the general use of an 'A' clamp, which is versatile and can be employed in various applications beyond just anterior teeth.
