  		Figure 1. Effect of curing temperature on the degree of monomer conversion near the surface. (A) Temperature measured during microwave (open circles), visible-light (closed squares), and thermal (closed circles) curing (mean ± SD; n = 4 for each method) of an unfilled 50:50 (mol:mol) Bis-GMA:TEGDMA resin. (B) Degree of conversion as a function of depth for the polymers obtained by the preceding 3 methods (mean ± SD; n = 3 for each group).
