Dental biomaterials reviews the materials used in this important area, their performance and how such performance can be measured and optimised. Chapters review optical and electron microscopy imaging techniques for dental biomaterial interfaces. Specific materials such as dental cements, fibre-reinforced composites, metals and alloys are discussed. There is an analysis of stresses, fracture, wear and ageing in dental biomaterials as well as an evaluation of the performance of dental adhesives and resin-dentin bonds. Chapters also review ways of assessing the performance of dental handpieces,

This superbly illustrated book provides detailed information on the causes of instrument failure during endodontic treatment, the factors influencing the management of such cases, and the diverse management options that may be employed to resolve the problem. Readers will find clear descriptions and comparative evaluation of the available methods, techniques, and devices. Complications that may arise during the management of fractured instruments are described, and the impact of retained file fragments on the prognosis of endodontic treatment is discussed. In addition, means of preventing iatrogenic errors from occurring in the first place (the best form of management) are explained, emphasizing that the risk of instrument failure is reduced if proper guidelines are carefully considered and followed. The book will assist both endodontists and general dental practitioners in achieving an optimal outcome when confronted with the time-consuming and challenging task of dealing with a fractured instrument within the root canal – a still frequent circumstance despite the plethora of improvements in instrument design, alloy composition, and manufacturing processes.

"Despite the force of Oregon's founding mythology, the Willamette Valley was not an empty Eden awaiting settlement by hardy American pioneers. Rather, it was, as Melinda Jette explores in At the Hearth of the Crossed Races, one of the earliest sites of extensive intercultural contact in the Pacific Northwest. Jette's study focuses on the 'hearth' of this contact: French Prairie, so named for the French-Indian families who resettled the homeland of the Ahantchuyuk Kalapuyans. Although these families sought a middle course in their relations with their various neighbors, their presence ultimately contributed to the Anglo-American colonization of the region. By establishing farming and husbandry operations in the valley, the French-Indian settlers enhanced the Willamette Valley's appeal as a destination of choice for the Anglo-Americans who later emigrated to the Pacific Northwest via the Oregon Trail. Upon these emigrants' arrival, the social space for the people of the 'crossed races' diminished considerably, as the Anglo-Americans instituted a system of settler colonialism based on racial exclusion. Like their Native kin, the French-Indian families pursued various strategies to navigate the changing times and Jette's study of French Prairie takes on the relationships among all three: the French-Indian families, the indigenous peoples, and the Anglo-American settlers. With At the Hearth of the Crossed Races, Jette delivers a social history that deepens our understanding of the Oregon Country in the nineteenth century. This history of French Prairie provides a window into the multi-racial history of the Pacific Northwest and offers an alternative vision of early Oregon in the lives of the biracial French-Indian families whose community challenged notions of white supremacy, racial separation, and social exclusion"--
