Post-irradiation polymerization of composites containing bis-GMA and TEGDMA

摘要

Objective: this study was conducted to evaluate the effect of the amount of TEGDMA on post-iradiation polymerization of bis-GMA based composites. Methods: Four experimental composites containing bis-GMA and TEGDMA at the ratios (W/W) of 75/25, 70/30, 67/33, and 50-50 were Prepared. The degree of conversion of each composite was measured by Fourier transformation infrared spectroscopy immediately after Being cured and after 24 h of storage, and the post-irradiation polymerization was determined.
