What chemical agent can be applied to retraction cord to control bleeding?

The application of a chemical agent to retraction cord for controlling bleeding is commonly done using Hemodent. Hemodent is a hemostatic agent, which means it is specifically designed to manage and reduce bleeding in dental procedures. Its formulation aids in coagulating tissues and promoting hemostasis, making it effective when placed on retraction cords used during dental impressions.

Other options, while they have their own uses in dental treatments, do not specifically target bleeding control in the same direct manner. For instance, oxidizing agents are typically used for disinfection or bleaching, chlorhexidine serves as an antiseptic and antimicrobial agent, and sodium hypochlorite is primarily known for its disinfecting properties and root canal procedures. However, none of these agents provide the specialized hemostatic function that Hemodent does when applied to retraction cords.
