Localized three-body wear of resin composites. 1994

Department of Operative Dentistry, Osaka University, Japan.

Localized wear tests have been performed on six resin composites using a recently developed three-body wear testing machine. After repeated loading to the composites, the worn surface was replicated. Then the wear values of the respective resin composites were determined from the surface area of the worn defect using an image-analyzer. In addition, the microstructure of the worn area was analyzed with a scanning electron microscope (SEM). This study revealed that a fine particle hybrid composite exhibited the greatest localized wear resistance of all resin composites investigated in this study. SEM of the microfilled resin composites showed some degradation between filler and matrix.

UI	MeSH Term	Description	Entries
D008422	Materials Testing	The testing of materials and devices, especially those used for PROSTHESES AND IMPLANTS; SUTURES; TISSUE ADHESIVES; etc., for hardness, strength, durability, safety, efficacy, and biocompatibility.	Biocompatibility Testing,Biocompatible Materials Testing,Hemocompatibility Testing,Testing, Biocompatible Materials,Testing, Hemocompatible Materials,Hemocompatibility Testings,Hemocompatible Materials Testing,Materials Testing, Biocompatible,Materials Testing, Hemocompatible,Testing, Biocompatibility,Testing, Hemocompatibility,Testing, Materials,Testings, Biocompatibility
D008855	Microscopy, Electron, Scanning	Microscopy in which the object is examined directly by an electron beam scanning the specimen point-by-point. The image is constructed by detecting the products of specimen interactions that are projected above the plane of the sample, such as backscattered electrons. Although SCANNING TRANSMISSION ELECTRON MICROSCOPY also scans the specimen point by point with the electron beam, the image is constructed by detecting the electrons, or their interaction products that are transmitted through the sample plane, so that is a form of TRANSMISSION ELECTRON MICROSCOPY.
