This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Exposure to beryllium (Be) can lead to lung pathologies, such as chronic beryllium disease (CBD). This occupational illness has been more prevalent among dental technicians compared to the non-exposed population. Although most manufacturers state that dental materials are Be-free, this prevalence raises the question of whether the materials are completely devoid of Be-traces. Thus, the objective of the present study was to analyze the elemental composition, with emphasis on Be, of a wide range of commercially available dental materials frequently used by dental laboratories. Samples of 32 different materials were collected and analyzed using inductively coupled plasma-optical emission spectrometry (ICP-OES) and X-ray fluorescence spectroscopy. The results showed that the Be content was below the limit of quantification in all included samples (

Download or read book Biocompatibility of Dental Materials written by Gottfried Schmalz and published by Springer Science & Business Media. This book was released on 2008-10-10 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive and scientifically based overview of the biocompatibility of dental materials. Up-to-date concepts of biocompatibility assessment are presented, as well as information on almost all material groups used in daily dentistry practice. Furthermore, special topics of clinical relevance (e.g,, environmental and occupational hazards and the diagnosis of adverse effects) are covered. The book will: improve the reader’s ability to critically analyze information provided by manufacturers supply a better understanding of the biocompatibility of single material groups, which will help the reader choose the most appropriate materials for any given patient and thus prevent adverse effects from developing provide insights on how to conduct objective, matter-of-fact discussions with patients about the materials to be used in dental procedures advise readers, through the use of well-documented concepts, on how to treat patients who claim adverse effects from dental materials feature clinical photographs that will serve as a reference when analyzing clinical symptoms, such as oral mucosa reactions.

Download or read book Extra Coronal Restorations written by Robert Wassell and published by Springer. This book was released on 2018-07-31 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a state of the art clinical guide to contemporary materials and techniques for the restoration of individual teeth and implants. It fully reflects the important developments in the field over the past 15 years, including in particular the shift away from wholesale use of crowns towards adhesive dentistry and less invasive extra-coronal restorations. The book opens by considering the principles and evidence base relating to the longevity of restorations of teeth and implants. Importantly, it explains how to ensure “a healthy start” and manage future risks. Material choice and aesthetic issues are then discussed, before all aspects of the planning and provision of extra-coronal restorations are examined in depth. The coverage also includes the adaptation of crowns to existing partial dentures. In line with modern dental education, each chapter begins with clinically relevant learning objectives, and helpful clinical tips are highlighted. The book will be of value for senior dental undergraduates, postgraduates, and practicing dentists and its scientific content will be of interest to dental academics.

Download or read book Extractive Metallurgy of Niobium written by A.K. Suri and published by Routledge. This book was released on 2017-11-13 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

This book was released on 2000-10-21 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Incineration has been used widely for waste disposal, including household, hazardous, and medical wasteâ€"but there is increasing public concern over the benefits of combusting the waste versus the health risk from pollutants emitted during combustion. Waste Incineration and Public Health informs the emerging debate with the most up-to-date information available on incineration, pollution, and human healthâ€"along with expert conclusions and recommendations for further research and improvement of such areas as risk communication. The committee provides details on: Processes involved in incineration and how contaminants are released. Environmental dynamics of contaminants and routes of human exposure. Tools and approaches for assessing possible human health effects. Scientific concerns pertinent to future regulatory actions. The book also examines some of the social, psychological, and economic factors that affect the communities where incineration takes place and addresses the problem of uncertainty and variation in predicting the health effects of incineration processes.
