Available in PDF, EPUB and Kindle. Book excerpt: Failures of restorations resulting from tooth fracture are one of the primary problems to lasting oral health. Fatigue cracks are often present in the dentin of restored teeth and their incidence increases with age of the patient. The primary objective of this investigation was to characterize the influence of microstructure, age and ethnicity on the crack growth resistance of human coronal dentin. Compact tension (CT) specimens were prepared from three regions (i.e. inner, middle and outer dentin) of the crown of 3rd molars obtained from young and old patients of the US and Colombia. Stable crack extension was achieved under Mode I quasi℗Ưstatic and cyclic loading. To understand the fundamental mechanisms of crack growth extension, the fracture surfaces were evaluated using scanning electron microscopy (SEM) and image processing techniques. Metrics related to the microstructure were correlated with the fatigue and fracture responses. Lastly, a hybrid approach was also used to quantify the contribution of toughening mechanisms to the overall toughness.

Available in PDF, EPUB and Kindle. Book excerpt: Mineralized tissues, such as bone and tooth dentin, serve as structural materials in the human body and, as such, have evolved to resist fracture. In assessing their quantitative fracture resistance or toughness, it is important to distinguish between intrinsic toughening mechanisms which function ahead of the crack tip, such as plasticity in metals, and extrinsic mechanisms which function primarily behind the tip, such as crack bridging in ceramics. Bone and dentin derive their resistance to fracture principally from extrinsic toughening mechanisms which have their origins in the hierarchical microstructure of these mineralized tissues. Experimentally, quantification of these toughening mechanisms requires a crack-growth resistance approach, which can be achieved by measuring the crack-driving force, e.g., the stress intensity, as a function of crack extension ("R-curve approach"). Here this methodology is used to study of the effect of aging on the fracture properties of human cortical bone and human dentin in order to discern the microstructural origins of toughness in these materials.

Download or read book Dynamic Mechanical Behavior of Human Dentin and Collagen written by Heonjune Ryou and published by . This book was released on 2015 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental evaluations of human coronal dentin and its collagen fibrils were performed by Dynamic Mechanical Analysis (DMA) using nanoindentation and Atomic Force Microscopy (AFM). The primary objectives were to quantify the changes in mechanical behavior of intertubular and peritubular dentin with age, and to evaluate the nanostructure and mechanical behavior of the collagen fibrils. Specimens of coronal dentin were evaluated by nanoDMA using single indents and in scanning mode via scanning probe microscopy. Collagen fibrils from coronal dentin were evaluated using Pulse-Force Mode (PFM) AFM (Peakforce QNM). Nanoindentation results showed that there were no significant differences in the storage modulus or complex modulus between the two age groups (18-25 versus 54-83 yrs) for either the intertubular or peritubular dentin. However, there were significant differences in the dampening behavior between the young and old tissues, as represented in the loss modulus and tanφ responses. For both the intertubular and peritubular components, the capacity for dampening was significantly lower in the old group. Scanning based nanoDMA showed that the tubules of old dentin exhibit a gradient in elastic behavior, with decrease in elastic modulus from the cuff to the center of tubules filled with newly deposited mineral. AFM results showed that the stiffness of the old dentin fibrils in the peak and trough regions were greater than the young dentin fibrils. In addition, there were significant differences in the dampening behavior between the young and old dentin fibrils, as represented in the energy dissipation, phase angle and loss modulus responses. For both the peak and trough regions, the dissipative capacity was significantly lower in the old dentin fibrils.
