Available in PDF, EPUB and Kindle. Book excerpt: The enamel of human teeth is generally regarded as a brittle material with low fracture toughness. Consequently, the contributions of this tissue in resisting tooth fracture and the importance of its complex microstructure have been largely overlooked. The primary objective of this dissertation is to characterize the role of enamel's microstructure and degree of decussation on the fracture behavior of human enamel. The importance of the protein content and aging on the fracture toughness of enamel were also explored. Incremental crack growth in sections of human enamel was achieved using a special inset Compact Tension (CT) specimen configuration. Crack extension was achieved in two orthogonal directions, i.e. longitudinal and transverse to the prism axes. Fracture surfaces and the path of crack growth path were evaluated using scanning electron microscopy (SEM) to understand the fundamental mechanisms of crack growth extension. Furthermore, a hybrid approach was adopted to quantify the contribution of toughening mechanisms to the overall toughness.

Download or read book Human Tooth and Developmental Dental Defects written by Ana Gil De Bona and published by BoD – Books on Demand. This book was released on 2022-07-27 with total page 171 pages. Available in PDF, EPUB and Kindle. Book excerpt: The unique tissues of human teeth, enamel, and dentin have been studied by scientists to understand their structure, physical and chemical properties, and the developmental machinery behind these extraordinary properties. During the developmental process, genetic, and environmental factors or the interplay between them may cause defects in dental hard tissues, impairing their biology and function. These defects have long been studied to provide better dental care and to find novel treatment options. Understanding the mechanical, chemical, and structural differences in developmental dental defects is also crucial for a routine dental practice, as many of these lesions do not have pathognomonic properties. This book focuses on the qualitative and quantitative properties of the sound enamel and dentin as well as the affected human tooth structures. It examines how genetics impact oral and dental health, the role of fluoride and trace elements in mineralization and the related clinical implications, and the impact of different approaches to diagnose and treat these developmental disorders.

Download or read book Teeth A Very Short Introduction written by Peter S. Ungar and published by OUP Oxford. This book was released on 2014-03-27 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: Teeth are amazing - the product of half a billion years of evolution. They provide fuel for the body by breaking apart other living things; and they must do it again and again over a lifetime without themselves being broken in the process. This means that plants and animals have developed tough or hard tissues for protection, and teeth have evolved ways to sharpen or strengthen themselves to overcome those defences. And just as different jobs require different tools, animals with different diets have different shaped teeth to deal with the variety of foods that they eat. In this Very Short Introduction, Peter S. Ungar, an award-winning author and leading scientist, presents the story of teeth. Ungar outlines the key concepts, including insights into the origin of teeth and their evolution. Considering why teeth are important, he describes how they are made, and how they work, including their fundamental importance in the fossil record. Ungar finishes with a review of mammal teeth, looking at how they evolved and how recent changes to our diet are now affecting dental health. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly.

Download or read book The Damage Tolerance of Teeth written by Amir Barani Lonbani and published by . This book was released on 2013 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: [Truncated abstract] This thesis is concerned with the fracture analysis of cracks in the teeth of different species. The main focus is on finding a link between the resistance to failure by fracture and the key geometrical features of the tooth, with particular reference to its radius, height and enamel thickness. The analysis is applied to short, rounded 'bunodont' molars typical of humans and other primates; elongated, columnar 'hypsodont' molars of ruminants and the elongated, tapered canine teeth of predators. Fracture morphologies include longitudinal cracks resulting from direct occlusal loading on bunodont and hypsodont crowns, and transverse cracking of the canine resulting from lateral loading. The study was carried out by applying numerical (extended finite element method (XFEM)), experimental and analytical fracture mechanics analyses resulting in simplified analytical equations for failure load in terms of the key parameters. The ability to model the failure of a particular tooth structure allows us to predict the maximum biting force that can be applied by the animal. The existing fracture patterns in the dentition of extant animals and also in fossil records show particular damage patterns that can also be analysed to determine the magnitude and type of load that caused the damage. Hence, the result of this research can be applied by anthropologists and paleoanthropologists help understand the evolutionary route of the species. Although the geometrical features of teeth in different mammalian species vary widely, available data suggests that the mechanical properties for the component materials (enamel, dentin) do not vary greatly. Nevertheless, the impact of microstructure cannot be neglected. The modelling has therefore also tested the relevance of local spatial variations in material properties within the enamel (stiffness and toughness) and material anisotropy. It is believed that many well developed cracks in teeth originate from pre-existing flaws in the enamel ('tufts') at the enamel-dentin junction (EDJ). Therefore, a two dimensional XFEM crack propagation in a region close to occlusal surface was implemented to study the effect of enamel anisotropy on the growth of tufts across the enamel thickness evolution from EDJ. The analysis was performed for both isotropic and orthotropic material properties for comparison. A higher crack driving force was observed in the isotropic material, indicating that anisotropy may be important, at least in the early stages of tuft growth. The next phase of our study was to consider the evolution of a longitudinal crack emanating from a small starting crack either at a cusp (radial crack) or at the base (margin crack) of a bunodont crown, under simulated occlusal loading. It is shown that both forms of crack behave in similar ways once well established, leading to ribbon-like channel (longitudinal) cracks that run up or down the sidewall of the tooth. The entire history (load-length) of the crack can be calculated, leading to simple explicit equations that link the critical failure load to the important tooth geometrical characteristics...

Download or read book Tooth Enamel Research Enamel 10 and beyond written by Pamela Den Besten and published by Frontiers Media SA. This book was released on 2023-11-20 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Research Topic will host an overview of the most recent knowledge on enamel issued from a group of international experts who gathered at the 10th International Symposium on Dental Enamel (Enamel X). The Topic will include manuscripts describing original data, short communication, and reviews. In addition, the Topic will host abstracts and panel discussions presented at the Enamel X meeting, to highlight changing paradigms, unsolved and challenging questions, as well as translational challenges. Bringing together physics, chemistry, biochemistry and development and differentiation, contributions to this Topic will focus on the unique architecture of enamel, from nano- to macro- scale, and the dynamic molecular interactions with lead to extracellular self-assembly and mineralization. This knowledge will open a window into innovative bioinspired treatment and materials for tissue repair and regeneration. Tissue-specific networks and pathways shared with a number of biological systems (clock genes, epithelial polarization/ion handling, cell niche dynamics, and cell signaling) will also be explored. This will give an overall picture of the multiple acellular, cellular and organismal (essentially transgenic mice) processes actively investigated in the enamel field. Similarly, lessons from isolated or syndromic, inherited and acquired enamel defects obtained using cutting edge cell and matrix-omics will establish the emerging genomic framework determining enamel quality. Tooth enamel defects reflect historical and present gene-environment interactions in the animal and human condition such as climate, nutrition, pollutants or fluoride exposures. This last fact is highly relevant in medicine and public health since poor tooth quality and mineral defects are one of the first human worldwide pathologies.
