Journal ArticleDOI
Adhesive/Dentin Interface: The Weak Link in the Composite Restoration
Paulette Spencer,Qiang Ye,Jong-Gu Park,Elizabeth M. Topp,Anil Misra,Orestes Marangos,Yong Wang,Brenda S. Bohaty,Viraj Singh,Fabio Sene,John Eslick,Kyle V. Camarda,J. Lawrence Katz,J. Lawrence Katz +13 more
TL;DR: The article will examine the various avenues that have been pursued to address problems and it will explore how alterations in material chemistry could address the detrimental impact of physico-chemical stresses on the bond formed at the adhesive/dentin interface.
Journal ArticleDOI
Adhesive phase separation at the dentin interface under wet bonding conditions.
Paulette Spencer,Yong Wang +1 more
TL;DR: The morphologic results in corroboration with the spectroscopic data suggest that as a result of adhesive phase separation the hybrid layer is not an impervious 3-dimensional collagen/polymer network but a porous web characterized by hydrophobic BisGMA-rich particles distributed in a hydrophilic HEMA-rich matrix.
Journal ArticleDOI
Hybridization Efficiency of the Adhesive/Dentin Interface with Wet Bonding
Yong Wang,Paulette Spencer +1 more
TL;DR: The histomorphologic and spectroscopic results suggest that, under wet bonding, the a/d interface is a porous collagen web infiltrated primarily by the hydrolytically unstable HEMA.
Journal Article
Characterization of enamel exposed to 10% carbamide peroxide bleaching agents.
TL;DR: Scanning electron microscopic evaluation revealed significant surface alterations in enamel topography for slabs treated with the bleaching solutions for 4 weeks, and the most severe alterations were found in slabs exposed to the lower-pH solutions.
Journal ArticleDOI
Anisotropic elasticity of cortical and cancellous bone in the posterior mandible increases peri-implant stress and strain under oblique loading
TL;DR: Anisotropy has subtle, yet significant effects on interface stresses and peri-implant strains and careful consideration should be given to its use in finite element studies of dental implants.
