Collagen Degradation by Host-derived Enzymes during Aging
Incompletely infiltrated collagen fibrils in acid-etched dentin are susceptible to degradation. We hypothesize that degradation can occur in the absence of bacteria. Partially demineralized collagenExpand

State of the art etch-and-rinse adhesives.
OBJECTIVES The aim of this study was to explore the therapeutic opportunities of each step of 3-step etch-and-rinse adhesives. METHODS Etch-and-rinse adhesive systems are the oldest of theExpand

Two Modes of Nanoleakage Expression in Single-step Adhesives
Self-etch adhesives that etch, prime, and bond simultaneously should not exhibit incomplete resin infiltration within hybrid layers. We hypothesized that nanoleakage patterns in these systems areExpand

Microtensile bond strength between adhesive cements and root canal dentin.
OBJECTIVES The hypotheses tested were that the bond strength of adhesive cements to root canal dentin (1) would be reduced as a function of configuration factor, polymerization process and type ofExpand

Reversal of Compromised Bonding in Bleached Enamel
Oxygen inhibits polymerization of resin-based materials. We hypothesized that compromised bonding to bleached enamel can be reversed with sodium ascorbate, an anti-oxidant. Sandblasted human enamelExpand

Calcium phosphate phase transformation produced by the interaction of the portland cement component of white mineral trioxide aggregate with a phosphate-containing fluid.
The bioactivity of mineral trioxide aggregate (MTA) has been attributed to its ability to produce hydroxyapatite in the presence of phosphate-containing fluids. It is known that stoichiometricExpand

Tensile Properties of Mineralized and Demineralized Human and Bovine Dentin
The relative contribution of the matrix of dentin to the physical properties of dentin is unknown but thought to be small. The objective of this study was to test the hypothesis that theExpand

Reversal of Compromised Bonding to Oxidized Etched Dentin
The mechanism responsible for hydrogenperoxide- or sodium-hypochlorite-induced reductions in dentin bond strength is unknown. This in vitro study tested the hypothesis that these oxidizing agentsExpand
