A Microshear Test to Measure Bond Strengths of Dentin-Polymer Interfaces

June 1, 2002
Author(s)
Walter G. McDonough, Joseph M. Antonucci, J He, Y Shimada, Martin Y. Chiang, Gary E. Schumacher, Carl R. Schultesiz
Mechanical property tests such as the diametral tensile, uniaxial tensile and transverse strength tests are commonly used in studying the interfacial properties of the bond between dental composites and dental substrates such as dentin and enamel. These

Influence of Processing Rate and Formulation on the Interface Strength of Vinyl Ester/E-Glass Composites

April 1, 2002
Author(s)
Walter G. McDonough, Joy Dunkers, Gale A. Holmes, E Feresenbet, Y H. Kim, Richard~undefined~undefined~undefined~undefined~undefined Parnas
The single fiber fragmentation test was used to investigate the effect of gelation time on interfacial shear properties of fast reacting resin systems. We developed a processing system capable of producing single fiber fragmentation samples with gelation

Interfacial Shear Strengths of Dental Resin-Glass Fibers by the Microbond Test

November 1, 2001
Author(s)
Walter G. McDonough, Joseph M. Antonucci, Joy Dunkers
In this study, the feasibility of using the microbond test (MBT) to probe the durability of the bond between a dental resin with differently silanized E-glass fibers was investigated. The E-glass fibers were silanized with equivalent amounts of two types

A Novel Microshear Test to Measure Dental Adhesion

February 1, 2001
Author(s)
Joseph M. Antonucci, Walter G. McDonough, Gary E. Schumacher, Y Shimada
A key factor in determining the strength and durability of polymeric dental restorative composites, sealants and adhesives is the quality of their interfaces/interphases. Bulk mechanical strength tests such as tensile, transverse and shear tests are

Single Fiber Composites: A New Methodology for Determinig Interfacial Shear Strength

September 1, 2000
Author(s)
Gale A. Holmes, Donald L. Hunston, Walter G. McDonough, R C. Peterson
Two of the critical factors controlling the long-term performance and durability of composites in structural applications is the fiber-matrix interfacial shear strength (IFSS) and the durability of the fiber-matrix interface. The single fiber fragmentation

Critical Issues in the Characterization of Polymers for Medical Applications

June 1, 2000
Author(s)
Walter G. McDonough, Eric J. Amis, J Kohn
On June 14, 2000, the New Jersey Center for Biomaterials and the Polymers Division of the National Institute of Standards and Technology (NIST) co-sponsored a one-day workshop on Critical Issues in the Characterization of Polymers for Medical Applications
