Bond strength of adhesives to dentin contaminated with smoker’s saliva
(Springer Verlag, 2010-02)The purpose of this study was to determine the effects of contamination with smoker’s and non-smoker’s saliva on the bond strength of resin composite to superficial dentin using different adhesive systems. The interfacial ... -
Bioactive Microsphere-Based Scaffolds Containing Decellularized Cartilage
(Wiley, 2015-07)The aim of this study was to fabricate mechanically functional microsphere-based scaffolds containing decellularized cartilage (DCC), with the hypothesis that this approach would induce chondrogenesis of rat bone marrow-derived ... -
Gravity-Driven Thin Film Flow of an Ellis Fluid
(Elsevier, 2013-12-01)The thin film lubrication approximation has been studied extensively for moving contact lines of Newtonian fluids. However, many industrial and biological applications of the thin film equation involve shear-thinning fluids, ... -
Contact Line Instability of Gravity-Driven Flow of Power-Law Fluids
(Elsevier, 2015-11)The moving contact line of a thin fluid film can often corrugate into fingers, which is also known as a fingering instability. Although the fingering instability of Newtonian fluids has been studied extensively, there are ... -
Viscoelastic and fatigue properties of model methacrylate-based dentin adhesives
(Wiley, 2010-11)The objective of the current study is to characterize the viscoelastic and fatigue properties of model methacrylate-based dentin adhesives under dry and wet conditions. Static, creep, and fatigue tests were performed on ... -
Mechanical properties of methacrylate-based model dentin adhesives: Effect of loading rate and moisture exposure
(Wiley, 2013-11)The aim of this study is to investigate the mechanical behavior of model methacrylate-based dentin adhesives under conditions that simulate the wet oral environment. A series of monotonic and creep experiments were performed ... -
Effect of Photoinitiator System and Water Content on Dynamic Mechanical Properties of a Light-cured bisGMA/HEMA Dental Resin
(Wiley, 2010-01-15)The selection of an appropriate photoinitiator system is critical for efficient polymerization of dental resins with satisfactory mechanical and physical properties. The purpose of this study was to evaluate the influence ... -
Viscoelastic Properties of Collagen-Adhesive Composites under Water Saturated and Dry Conditions
(Wiley, 2015-02)To investigate the time and rate dependent mechanical properties of collagen-adhesive composites, creep and monotonic experiments are performed under dry and wet conditions. The composites are prepared by infiltration of ... -
Effect of initiator on photopolymerization of acidic, aqueous dental model adhesives
(Wiley, 2009-09-15)This study evaluated different initiator systems in self-etching model adhesives, in which camphorquinone (CQ) or [3-(3,4-dimethyl-9-oxo-9H-thioxanthen-2-yloxy)-2-hydroxylpropy] trimethylammonium chloride (QTX) was employed ... -
Detection of cocaine induced rat brain activation by photoacoustic tomography
(Elsevier, 2011-02-15)Photoacoustic tomography (PAT) was used to detect the progressive changes on the cerebral cortex of Sprague Dawley rats after the administration of cocaine hydrochloride. Different concentrations (0, 2.5, and 5.0 mg per ... -
A novel device to measure power grip forces in squirrel monkeys
(Elsevier, 2009-05-15)Understanding the neural bases for grip force behaviors in both normal and neurologically impaired animals is imperative prior to improving treatments and therapeutic approaches. The present paper describes a novel device ... -
Adhesive/Dentin Interface: The Weak Link in the Composite Restoration
(Springer Verlag, 2010-06)Results from clinical studies suggest that more than half of the 166 million dental restorations that were placed in the United States in 2005 were replacements for failed restorations. This emphasis on replacement therapy ... -
Scanning Acoustic Microscopy Investigation of Frequency-Dependent Reflectance of Acid-Etched Human Dentin Using Homotopic Measurements
(Institute of Electrical and Electronics Engineers, 2011-03)Composite restorations in modern restorative dentistry rely on the bond formed in the adhesive-infiltrated acid-etched dentin. The physical characteristics of etched dentin are, therefore, of paramount interest. However, ... -
Lumbar Position Sense with Extreme Lumbar Angle
(Elsevier, 2008-05-06)Tasks involving flexed torso postures have a high incidence of low back injuries. Changes in the ability to sense and adequately control low back motion may play a role in these injuries. Previous studies examining position ... -
Compositional design and optimization of dentin adhesive with neutralization capability
(Elsevier, 2015-07-02)Objectives The objective of this work was to investigate the polymerization behavior, neutralization capability, and mechanical properties of dentin adhesive formulations with the addition of the tertiary amine co-monomer, ... -
Novice Lifters Exhibit A More Kyphotic Lifting Posture Than Experienced Lifters In Straight-Leg Lifting
(Elsevier, 2015-06-04)As torso flexion and repetitive lifting are known risk factors for low back pain and injury, it is important to investigate lifting techniques that might reduce injury during repetitive lifting. By normalizing lumbar posture ... -
EFFECTIVENESS OF SURGICAL RECONSTRUCTION TO RESTORE RADIOCARPAL JOINT MECHANICS AFTER SCAPHOLUNATE LIGAMENT INJURY. AN IN VIVO MODELING STUDY
(Elsevier, 2013-04-22)Disruption of the scapholunate ligament can cause a loss of normal scapholunate mechanics and eventually lead to osteoarthritis. Surgical reconstruction attempts to restore scapholunate relationship and shows improvement ... -
