Journal ArticleDOI
Collagen Degradation by Host-derived Enzymes during Aging
David H. Pashley,Franklin R. Tay,Cky Yiu,Mamoru Hashimoto,Lorenzo Breschi,Ricardo M. Carvalho,Shuichi Ito +6 more
TL;DR: It is hypothesized that collagen degradation occurred over time, via host-derived matrix metalloproteinases that are released slowly over time through proteolytic enzyme inhibitors or mineral oil.
Journal ArticleDOI
Relationship between surface area for adhesion and tensile bond strength — Evaluation of a micro-tensile bond test
Hidehiko Sano,Tsunekazu Shono,Hidekazu Sonoda,T Takatsu,B. Ciucchi,Ricardo M. Carvalho,David H. Pashley +6 more
TL;DR: This new method permits measurement of high bond strengths without cohesive failure of dentin and it also permits multiple measurements to be made within a single tooth.
Journal ArticleDOI
State of the art etch-and-rinse adhesives
David H. Pashley,Franklin Chi Meng Tay,Lorenzo Breschi,Leo Tjäderhane,Ricardo M. Carvalho,Marcela Carrilho,Marcela Carrilho,Arzu Tezvergil-Mutluay +7 more
TL;DR: The therapeutic potential of etch-and-rinse adhesives has yet to be fully exploited, and incorporation of protease inhibitors in etchants and/or cross-linking agents in primers may increase the durability of resin-dentin bonds.
Journal ArticleDOI
Single-step adhesives are permeable membranes.
TL;DR: Morphological manifestations of delayed light-activation of composite in the hydrated dentine bonding substrate were exclusively located along the composite-adhesive interface, and were present as large voids, resin globules and honeycomb structures that formed partitions around a myriad of small blisters along the fractured interfaces.
Journal ArticleDOI
Effects of resin hydrophilicity on water sorption and changes in modulus of elasticity.
Shuichi Ito,Masanori Hashimoto,Bakul Wadgaonkar,Nádia da Rocha Svizero,Ricardo M. Carvalho,Cynthia K.Y. Yiu,Frederick A. Rueggeberg,Stephen H. Foulger,Takashi Saito,Yoshihiro Nishitani,Masahiro Yoshiyama,Franklin R. Tay,David H. Pashley +12 more
TL;DR: Comparing the water sorption and modulus of elasticity of five experimental neat resins of increasing hydrophilicity, as ranked by their Hoy's solubility parameters and five commercial resins found all resins stored in water exhibited a time-dependent decrease in modulus that was proportional to their degree of water Sorption.
