[Polymerization of flowable composite core materials irradiated by super-high intensity light with short time].

Purpose: To evaluate the polymerization of dual-cured flowable composite core irradiated by super-high intensity light with short time.

Methods: The light-proof silicon rubber cuboid mold with one end open was syringed and filled by dual-cured flowable resin composite core, then the open end of mold was irradiated directly by a light unit at 1000 mW/cm(2) ×10, ×20 s; or at 3200 mW/cm(2) × 3, ×6 s. The specimens were stored in the light-proof box.
