“…It is concluded that the paramagnetic species in the sample are the "propagating" and "allylic" radicals shown by Fontes et al 23 , which generated during the irradiation of the sample. These radicals are present in the sample even one month after the irradiation because of the vitrification phenomenon, although in much less concentration 13 . The reaction kinetics of dental materials is dependent on the initial concentration of monomers and initiators, as well as the light intensity and depth of cure and temperature 26 .…”

“…When the polymerization degree of the resin cement does not reach satisfactory levels, its mechanical properties are compromised 6,11,12 . The initial concentration of free radicals is crucial to promote better clinical results and is directly connected to the degree of conversion of monomers to polymers 13 , so that the knowledge of the variables that affects the initial amount of free radicals generated is fundamental to de development of more efficient materials and technics.…”

“…12 This method was successfully employed in a study of the curing time of visible-light-activated composites as a function of the sample thickness as well as in other investigations involving dental composites. [13][14][15][16] The influence of the free-radical concentration in the underneath composite layer on the effectiveness of the bonding between dental composites has not been investigated yet. Therefore, the aim of our study was to clarify the role of the free-radical concentration on the shear bond strength between two layers of composite using the EPR method and simultaneously to verify the polymerisation process by measuring the DC using Raman spectroscopy.…”
