摘要:
A dental retraction cord is used within dental procedures as the dental retraction cord is impregnated with at least one dental anesthetic agent and/or a vasoconstrictor agent so that the dental retraction cord is able to reduce the pain and discomfort during the cord packing process. A plurality of interlocking strands of the dental retraction cord is impregnated with the at least one dental anesthetic agent and/or the vasoconstrictor agent as the dental retraction cord is stored within a container. The at least one dental anesthetic agent and/or the vasoconstrictor agent are activated upon contact with liquid in order to create additional numbness and to reduce loss of blood during the dental procedures.
