Core Paste XP auto-mixing syringe is easy to use and creates up to 60% less waste than cartridge systems that require a dispensing gun. The stackable viscosity allows you to build up without a matrix or core form and the dual-cure formula gives you the confidence of a self-cure with the option of light-curing to speed the procedure. Core Paste XP Syringe is a creamy, radiopaque paste developed specifically for high-strength, reliable, core build-ups. When there is insufficient tooth structure available for a fixed prosthesis, Core Paste XP Syringe provides the added strength and stability needed for long-term clinical success.
