The development of surface hardness in hard chairside reline resins
(American Association for Dental Research (AADR), 2000-05-01)
Effect of repeated cycles of chemical disinfection on the roughness and hardness of hard reline acrylic resins
(WILEY-BLACKWELL, 2010)
Objective: The aim of this study was to assess the effect of repeated cycles of five chemical disinfectant solutions on the roughness and hardness of three hard chairside reliners. Methods: A total of 180 circular specimens ...
Long-term surface hardness and monomer conversion of a nonofilled and a microhybrid composite resin
(2013)
Objective: This study aims to evaluate the degree of conversion (DC) and hydrolytic degradation through the Vickers hardness test (HV) of a nanofilled (Filtek™ Z-250, 3M) and a microhybrid (Filtek™Supreme-XT, 3M) composite ...
Analysis of surface hardness of artificially aged resin composites
(ABM, ABC, ABPol, 2012)
This study evaluated the effect of artificially accelerated aging (AAA) on the surface hardness of eight composite resins: Filtek Z250, Filtek Supreme, 4 Seasons, Herculite, P60, Tetric Ceram, Charisma, and Filtek Z100. ...
Properties of the hard-sphere fluid at a planar wall using virial series and molecular-dynamics simulation
(American Institute of Physics, 2018-07)
We study the hard-sphere fluid in contact with a planar hard wall. By combining the inhomogeneous virial series with simulation results, we achieve a new benchmark of accuracy for the calculation of surface thermodynamics ...
An investigation of electrolytic surface damages and electroplated crhomium effects on fatigue behavior of high strength steel
(2001-12-01)
Fatigue crack initiation occurs at the surface, although sub surface nucleation has also been reported. Localized imperfections like inclusions close to surface and surface small pits can result in crack sources. Coatings ...

Effect of disinfectants on the hardness and roughness of reline acrylic resins
(2006-07-01)
Purpose: Potential effects on hardness and roughness of a necessary and effective disinfecting regimen (1% sodium hypocholorite and 4% chlorhexidine) were investigated for two hard chairside reline resins versus a ...
