Ultradent: UltraPak Ret Cord
Ultrapak cord is made of 100% cotton, knitted into thousands of tiny loops to form long, interlocking chains. This unique knitted design exerts a gentle, continuous outward force following placement, as the knitted loops seek to open. Optimal tissue displacement occurs in 3–8 minutes. Ultrapak E is impregnated with racemic epinephrine hydrochloride.
