Compressive strength

Additionally, measurements of the curing performance of the SmartLite PS were
compared to that of the Spectrum800@800 by measuring the compressive strength of
EsthetX A2 and A4 and Spectrum TPH A2 and A4 shades, respectively. Results are
shown in Figure 10. The obtained values for the compressive strength of the cured
materials confirm that there is no difference between the curing performance of the
SmartLite PS and the Spectrum800 at 800 mW/cm
