Topic: Staining at porcelain margin?
Had a doctor ask me about astrigendent vs hemadent. Does one cause dark staining at the margin?
Re: Staining at porcelain margin?
Avoid using any material with Ferric Sulfate and use aluminum chloride instead. Use ViscoStat "clear" from Ultradent as you can use their nice little syringes and tips. hemodent is aluminum chloride also.
