Implication

Observational analysis reveals significant polymerization delay in resin-based composites, indicating thickness and irradiance both influence the curing process.

Key Points

A significant time delay before polymerization occurs was observed at the bottom surface of each resin-based composite.
At an irradiance of 942 mW/cm2, the delay ranged from 0.12 to 1.11 seconds in 2 mm thick RBCs.
For thicker 4 mm RBCs, even high irradiance of 1969 mW/cm2 resulted in delays of 0.12 to 5.17 seconds.
The highest irradiance of 3985 mW/cm2 did not completely eliminate the polymerization delay caused by increased thickness.
