What type of agent is applied to retraction cord to control bleeding?

The appropriate agent used to control bleeding when applied to retraction cords is a hemostatic solution. Hemostatic solutions are specially formulated to promote clotting and minimize blood loss during dental or surgical procedures. These solutions can be made from various materials, including topical thrombin, epinephrine, or other active compounds that enhance the coagulation process.

By controlling bleeding effectively, hemostatic solutions help provide a clearer surgical field, facilitating better visibility and access for the clinician. This is particularly important in dental contexts where precision is essential for successful outcomes.

Other types of solutions, while useful for different purposes, do not specifically address bleeding control. Antiseptic solutions aim to reduce the risk of infection, antibiotic ointments serve to prevent bacterial growth, and local anesthetics primarily provide pain relief rather than contribute to hemostasis.
