“PermaFlo DC, a composite luting/restorative material, has some unique capabilities. It has been put under the category of “dual-cure” because that’s well known to dentists. However, in reality, an actual dual-cure product would be able to be a stand-alone light cure product. Or, it would be a stand-alone chemical cure product in two separate, disconnected syringes,” Dr. Fischer, Ultradent founder, and president remarks. “The challenge with that, for years, was that all ‘dual-cure composites’, if used only in the chemical cure mode, would never polymerize as completely as they should, and would never come out as strong as they could if they had been light activated.” He continues, “Where dentists really need a ‘dual-cure,’ is where adequate light can’t reach in the restoration to assure quality polymerization, like with an opacious crown or a restoration in the deep interproximal area, subgingivally.”
