Soft-Core carrier is 30% thinner than Thermalfil, allowing greater flexibility to navigate curved canals. A thinner core also means more gutta percha for denser fills every time. And with just one universal taper size, greatly reduces and simplifies the carrier inventory. Clinically proven to provide a better seal. Soft-Core is make with the most advanced Alpha Phase gutta percha available, ensuring excellent flow ability, adhesive qualities and superior sealing capabilities. Recent studies show Soft-Core had 40% less microleakage than Thermafil.
