the effect of temperature on shear bond strength of clearfil se bond and adper single bond adhesive systems to dentin
statement of the problem: monomer viscosity and solvent evaporation can be affected by the adhesive system temperature. higher temperature can elevate the vapor pressure in solution and penetration of adhesive in smear layer. bonding mechanism may be influenced by the adhesive temperature. purpose: this study aimed to evaluate the effect of pre-heating on shear bond strength of etch-and-rinse a...
متن کاملDynamic breaking of a single gold bond
While one might assume that the force to break a chemical bond gives a measure of the bond strength, this intuition is misleading. If the force is loaded slowly, thermal fluctuations may break the bond before it is maximally stretched, and the breaking force will be less than the bond can sustain. Conversely, if the force is loaded rapidly it is more likely that the maximum breaking force is me...

متن کاملmicrotensile bond strength of single bond and adper prompt-l-pop adhesives to dentin
objective: the aim of this study was to evaluate the microtensile bond strength to sound and caries-affected dentin using single bond and adper prompt-l-pop adhesives. materials and methods: sixteen extracted human molars with carious lesions extended halfway through dentin were ground to expose the caries affected and the surrounding normal dentin. the samples were divided into two groups of e...
متن کاملStructure of the diamond (111) surface: Single-dangling-bond versus triple-dangling-bond face.
We present converged first-principles calculations for the atomic and electronic structure of diamond ~111! surfaces based on density-functional theory in the local-density approximation. Singleand triple-danglingbond surfaces with 131, 231, and (A33A3)R30° translational symmetry are studied by means of totalenergy minimizations. The ground-state geometries and electronic band structures are co...
