Which of the following describes the characteristics of retraction cords?

Retraction cords are specifically designed to assist in creating space around a tooth, particularly during dental procedures that require clear visibility and access to the tooth and surrounding areas. The characteristics of retraction cords, such as their textures, sizes, and thicknesses, are vital as they directly influence how effectively the cord maintains tissue retraction without causing trauma to the gingival tissues.

The texture of the cord can affect how easily it can be placed and removed, as well as how it interacts with the tissues. Sizes and thicknesses are also critical because they must be selected based on the specific clinical situation and the amount of retraction needed. Using a cord that is appropriately sized for the gingival sulcus helps ensure that it can maintain adequate retraction while minimizing discomfort for the patient.

Other options, while related to different aspects of dental products, do not address the specific functional characteristics of retraction cords in the context of their application in dental procedures.
