Summary The aim of this study was to evaluate the effects of post‐curing by heat on the mechanical properties of visible‐light (V‐L) cured three inlay composites and three posterior filling composites. One group was only photo‐cured according to the manufacturers' recommended methods, while the other group was heat‐treated at 100°C for 15 min following initial cure by V‐L. Knoop hardness, diametral tensile strength and compressive strength were measured to evaluate the mechanical properties. Cure performance was checked out by the solvent immersion test. Upon secondary‐curing by heat, it was confirmed that the mechanical properties of the composites were increased moderately and the cure performance of the composites was also improved.
