This book was released on 2012-07-24 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the structure-property relationship of enamel is a basis to improve restorative and preventive dentistry. The structure-mechanical properties relationship of dental enamel (made of apatite fibers and a small amount of organics and water) was studied. Enamel’s elastic moduli, elastic/inelastic transition were quantified and the toughening mechanisms were identified for different hierarchical levels. During creep, the interrod regions are able to dissipate higher irreversible energy compared to the enamel rod regions. For enamel fracture, the crack tip toughness, the cohesive stresses and size of the cohesive zone at the crack-tip were quantified.

Download or read book Atomistic Simulation of Anistropic Crystal Structures at Nanoscale written by Jia Fu and published by BoD – Books on Demand. This book was released on 2019-05-10 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multiscale simulations of atomistic/continuum coupling in computational materials science, where the scale expands from macro-/micro- to nanoscale, has become a hot research topic. These small units, usually nanostructures, are commonly anisotropic. The development of molecular modeling tools to describe and predict the mechanical properties of structures reveals an undeniable practical importance. Typical anisotropic structures (e.g. cubic, hexagonal, monoclinic) using DFT, MD, and atomic finite element methods are especially interesting, according to the modeling requirement of upscaling structures. It therefore connects nanoscale modeling and continuous patterns of deformation behavior by identifying relevant parameters from smaller to larger scales. These methodologies have the prospect of significant applications. I would like to recommend this book to both beginners and experienced researchers.

This book was released on 2013-11-18 with total page 998 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the processing of the 15th ICMBE held from 4th to 7th December 2013, Singapore. Biomedical engineering is applied in most aspects of our healthcare ecosystem. From electronic health records to diagnostic tools to therapeutic, rehabilitative and regenerative treatments, the work of biomedical engineers is evident. Biomedical engineers work at the intersection of engineering, life sciences and healthcare. The engineers would use principles from applied science including mechanical, electrical, chemical and computer engineering together with physical sciences including physics, chemistry and mathematics to apply them to biology and medicine. Applying such concepts to the human body is very much the same concepts that go into building and programming a machine. The goal is to better understand, replace or fix a target system to ultimately improve the quality of healthcare. With this understanding, the conference proceedings offer a single platform for individuals and organizations working in the biomedical engineering related field to gather and network with each other in so doing create the catalyst for future development of biomedical engineering in Asia.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Enamel, the outer protective layer of human teeth, is constantly interacting with its surrounding harsh environment. These interactions play a major role in many mechanisms that affect the dental health such as tooth caries, tooth discoloration and plaque formation. Accordingly, most treatments used to maintain and/or restore dental health focus first on the enamel surface. Even though most of the enamel structure has been thoroughly studied, many of the enamel surface features, and the chemical reaction that occur on it, are not well understood. Extrinsic tooth discoloration poses a major problem to many patients and dentists. Most causes of extrinsic tooth staining have been well identified and are usually treated with hydrogen peroxide. However, the mechanism of extrinsic tooth discoloration and tooth bleaching using peroxide oxidizers are not fully understood. It is unknown why certain staining molecules attach to the enamel surface, whether peroxide radicals make teeth whiter by removing these stains, and why sometimes hydrogen peroxide does not work. Also, treating darkened teeth with peroxide agents has its limitations and disadvantages. This has pushed us to look for better and less harmful whitening agents. Recent studies have revealed that there is a correlation between crystallographic characteristics of enamel and its physical properties, such as tooth shade and microhardness. This discovery predicts that tooth properties can be changed by modifying its crystallographic structure. Since magnesium ions are known to react with synthetic hydroxyapatite and affect its crystallographic properties, it is possible that magnesium ions could react with dental enamel and induce changes in dental enamel crystallographic, optical and mechanical properties. Several significant conclusions and achievements are presented in this thesis. We demonstrated the presence of a carbon rich layer on the surface of enamel that contains relatively high amounts of calcium. This layer might explain the high staining ability of certain types of anionic staining agents that are among the most common causes of external tooth discoloration. Moreover, we showed that hydrogen peroxide does not induce significant changes in tooth enamel organic and inorganic relative contents, and it whitens teeth just by oxidizing their organic matrix. This finding is of great clinical significance since it explains the mechanism of tooth bleaching and the reasons behind the limited predictability of the treatment outcomes. Finally, we showed for the first time that magnesium ions can react with tooth enamel and induce a reduction in the size of enamel hydroxyapatite nanocrystals. This change in crystallography affected the enamel optical and mechanical properties; making the enamel harder and whiter. This is a new method that can be exploited to whiten teeth without using peroxide-based bleaching agents. We concluded that crystallographic ultrastructure plays a key role in defining the tooth enamel properties which can be tailored through ionic substitution for improvement of optical and mechanical properties without causing the possible negative effects of peroxide agents." --

Download or read book Material Tissue Interfacial Phenomena written by Paulette Spencer and published by Woodhead Publishing. This book was released on 2016-09-30 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: Material-Tissue Interfacial Phenomena: Contributions from Dental and Craniofacial Reconstructions explores the material/tissue interfacial phenomena using dental and craniofacial reconstructions as a model system. As the mouth is a particularly caustic environment, the synthetic and/or bio-enabled materials used to repair damaged tissues and restore form, function, and esthetics to oral structures must resist a variety of physical, chemical, and mechanical challenges. These challenges are magnified at the interface between dissimilar structures such as the tooth/material interface. Interfacial reactions at the atomic, molecular, and nano-scales initiate the failure of materials used to repair, restore, and reconstruct dental and craniofacial tissues. Understanding the phenomena that lead to failure at the interface between dissimilar structures, such as synthetic materials and biologic tissues, is confounded by a variety of factors that are thoroughly discussed in this comprehensive book. - Provides a specific focus on the oral environment - Combines clinical views and basic science into a useful reference book - Presents comprehensive coverage of material-interfacial phenomena within the oral environment
