Light Core is a light cured core build up composite. Sculptable and non slumping, it provides optimal handling. Light Core has a 5mm depth of cure at 500 mW cm2. Light Core is available in two shades: Translucent and Blue. Translucent is ideal for use under aesthetic restorations, such as all ceramic crowns, inlays and onlays. Blue is ideal for use in conventional fixed restorations, such as metal based restorations (all metal or PFM). Blue facilitates placement when a contrast to tooth structure is desired. This contrast ensures your margins will be placed on tooth structure where they belong. Choose from economical syringes or convenient unit dose tips.
