Dataset on Conversion Degrees of Dual Cements by Photoactivation

Objetive. Determine the degrees of conversion and photoactivation of dual cements in vitro. Background .Properties of photopolymerized materials are influenced by the conversion level reached during polymerization. Materials and Methods:A comparative, cross-sectional in vitro study was performed. Two resinous cements were used (two groups with n = 6 samples each), which were analyzed before photoactivation, after photoactivation and 24 hours later. In the second group, the samples were photoactivated through a ceramic disc 1.5 mm thick, and they were analyzed with spectroscopy, including the Fourier transform and total reflection. Results :Allcem Veneer APS (FGM, Joinville, SC, Brazil) 44.9%, Allcem Dual, (FGM, Joinville, SC, Brazil) 51.89% at 24 hours Allcem Veneer: 61.47% Allcem Dual: 60.49%, in immediate scanning, activation via ceramic disc, Allcem Veneer: 37.25% Allcem Dual: 29.29% at 24 hours Allcem Veneer: 58.28% Allcem Dual: 60.97%. Conclusion: The degree of conversion showed significant differences after photoactivation in the two cements independent of the application .
