Abstract

Objective: This study aimed to identify post-cure's effect on the depth of cure (DOC) of a short fiber-reinforced resin composite (SFRC).

Methods: Six EverX PosteriorTM shade A3Â specimens were cured with a light-emitting diode light curing unit with 800Â mW/cm2 of light irradiation for 20 s. The specimens were divided into two groups. The first was measured immediately post-cure and the second was measured 24-h post-cure. They were measured with a Vickers microhardness profile test. An independent t-test was used to analyze the significance of the differences between the DOC value and different variables.

Results: The DOC of the specimens measured immediately post-cure was 3.02Â±0.02Â mm. The DOC of the specimens measured 24-h post-cure was 3.93Â±0.03Â mm.

Conclusion: The DOC of the specimens measured 24-h post-cure was significantly higher than the DOC of the specimens measured immediately post-cure. Post-cure polymerization (24-h post-cure) can increase the DOC values of an SFRC.
