What is a characteristic of braided cord in dental procedures?

A key characteristic of braided cord in dental procedures is its ability to increase size or thickness in the gingival sulcus. This property is particularly useful when creating space for impression materials or for ensuring accurate margins during crown or bridge placements. The braided structure allows for a greater degree of expansion, which helps to easily pack and support the tissue, ensuring optimal visibility and access during various dental procedures.

In contrast, options that describe the cord as suitable for narrow sulci or as made from natural fibers do not highlight its primary advantage of enhancing size. While some dental cords may be made from synthetic materials, emphasizing that they are made from natural fibers is not a defining characteristic, as many types of braided cord available today may use synthetic alternatives due to their stability and resistance to moisture. The notion that braided cord decreases size misrepresents its function, as its primary purpose is to effectively elevate and expand the surrounding tissue rather than constrict it.
