OBJECTIVES The aims of this study were to test whether the bond strength of a hybrid composite and a PMMA-based veneer to CAD/CAM polymers would improve after pre-treatment and to evaluate the failure types after debonding. MATERIALS AND METHODS Three types of PMMA-based (CAD-Temp, artBloc Temp and TelioCAD) CAD/CAM blocks were obtained (N = 360, n = 15 per test group). They were divided into...

OBJECTIVES The purpose of this study was to evaluate the effect of either eugenol-containing or eugenol-free temporary cement removal by excavator or sandblasting on the shear bond strength of ceramic luted to dentin. METHODS A self-etching primer system, Panavia F 2.0, Kuraray Medical (PF2), and a total-etch bonding system, Excite/Variolink II, Vivadent (EXV), were used. One hundred and fort...

We present experimental evidence which confirms recently proposed ring current prediction methods for assigning hydrogen-bond proton nuclear magnetic resonance (NMR) spectra from tRNA (Robillard, G. T., Tarr, C. E., Vosman, F., & Berendsen, H. J. C. (1976) Nature (London) 262, 363-369; Robillard, G. T., Tarr, C. E., Vosman, F., & Sussman, J. L. (1977) Biophys. Chem. 6, 291-298). The evidence is...

We use administrative data from the unemployment insurance system of the Sate of Washington to study the magnitude of the wage differential associated with work in the temporary services industry. We find that temp wage rates are 15% to 20% below the levels that might have been expected based on trends during other periods in workers’ careers even after controlling for differences between temps...

OBJECTIVE This study compared the marginal gap, internal fit, fracture strength, and mode of fracture of CAD/CAM provisional crowns with that of direct provisional crowns. MATERIAL AND METHODS An upper right first premolar phantom tooth was prepared for full ceramic crown following tooth preparation guidelines. The materials tested were: VITA CAD-Temp®, Polyetheretherketone "PEEK", Telio CAD-...
