Abstract

The purpose of this in vitro study will be evaluate the effects of different modes of photoactivation in the nanohardness and elastic modulus of resin cements and adhesives, as well as the effect on the color stability of ceramic laminates. The factors of the studies will be: two levels of light curing units (VALO - Ultradent; Radii Cal - SDI)and three modes of photoactivation (without prior curing of the adhesive system in the tooth surface and inside of the ceramic laminate, prior curing the adhesive system only in the tooth surface, and prior curing of the adhesive system in the tooth surface and within the ceramic laminate). 132 ceramic blocks (7x8x0.6mm) of lithium disilicate (IPS e-max CAD) will be made, which will be cemented on the enamel of bovine teeth, and distributed in 12 groups according to the restorative materials (Single Bond Universal/RelyX Veneer- 3M/ESPE and Excite DSC/Variolink Veneer - Ivoclar Vivadent) and methods of procedures (n = 11). The values of color stability, as well as the values of mechanical properties of adhesives and resin cements will be used to determine possible changes that will occur in the bonded interfaces. The color stability and mechanical properties data will be subjected to statistical normality tests and specific tests to verify the significance between means (p = 0.05). (AU)
