Available in PDF, EPUB and Kindle. Book excerpt: Most people associate fluoride with the practice of intentionally adding fluoride to public drinking water supplies for the prevention of tooth decay. However, fluoride can also enter public water systems from natural sources, including runoff from the weathering of fluoride-containing rocks and soils and leaching from soil into groundwater. Fluoride pollution from various industrial emissions can also contaminate water supplies. In a few areas of the United States fluoride concentrations in water are much higher than normal, mostly from natural sources. Fluoride is one of the drinking water contaminants regulated by the U.S. Environmental Protection Agency (EPA) because it can occur at these toxic levels. In 1986, the EPA established a maximum allowable concentration for fluoride in drinking water of 4 milligrams per liter, a guideline designed to prevent the public from being exposed to harmful levels of fluoride. Fluoride in Drinking Water reviews research on various health effects from exposure to fluoride, including studies conducted in the last 10 years.

This book was released on 1999-10-17 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1941, Recommended Dietary Allowances (RDAs) has been recognized as the most authoritative source of information on nutrient levels for healthy people. Since publication of the 10th edition in 1989, there has been rising awareness of the impact of nutrition on chronic disease. In light of new research findings and a growing public focus on nutrition and health, the expert panel responsible for formulation RDAs reviewed and expanded its approachâ€"the result: Dietary Reference Intakes. This new series of references greatly extends the scope and application of previous nutrient guidelines. For each nutrient the book presents what is known about how the nutrient functions in the human body, what the best method is to determine its requirements, which factors (caffeine or exercise, for example) may affect how it works, and how the nutrient may be related to chronic disease. The first volume of Dietary Reference Intakes includes calcium, phosphorus, magnesium, vitamin D, and fluoride. The second book in the series presents information about thiamin, riboflavin, niacin, vitamin B6, folate, vitamin B12, pantothenic acid, biotin, and choline. Based on analysis of nutrient metabolism in humans and data on intakes in the U.S. population, the committee recommends intakes for each age groupâ€"from the first days of life through childhood, sexual maturity, midlife, and the later years. Recommendations for pregnancy and lactation also are made, and the book identifies when intake of a nutrient may be too much. Representing a new paradigm for the nutrition community, Dietary Reference Intakes encompasses: Estimated Average Requirements (EARs). These are used to set Recommended Dietary Allowances. Recommended Dietary Allowances (RDAs). Intakes that meet the RDA are likely to meet the nutrient requirement of nearly all individuals in a life-stage and gender group. Adequate Intakes (AIs). These are used instead of RDAs when an EAR cannot be calculated. Both the RDA and the AI may be used as goals for individual intake. Tolerable Upper Intake Levels (ULs). Intakes below the UL are unlikely to pose risks of adverse health effects in healthy people. This new framework encompasses both essential nutrients and other food components thought to pay a role in health, such as dietary fiber. It incorporates functional endpoints and examines the relationship between dose and response in determining adequacy and the hazards of excess intake for each nutrient.

Available in PDF, EPUB and Kindle. Book excerpt: A lively account of fluoridation and its discontents Since its first implementation in Grand Rapids, Michigan, in 1945, public drinking water fluoridation and its attendant conflicts, controversies, and conspiracy theories serve as an object lesson in American science, public health, and policymaking. In addition to the arguments on the issue still raging today, the tale of fluoridation and its discontents also resonates with such present concerns as genetically modified foods, global warming response, nuclear power, and environmental regulation. Offering the best current thinking on the issue, The Fluoride Wars presents a witty and detailed social history of the fluoridation debate in America, illuminating the intersection of science and politics in our recent past. This reader-friendly assessment explores the pro- and anti-fluoridation movements, key players, and important events. Full of amusing and vivid anecdotes and examples, this accessible recounting includes: A careful and non-condescending look at the hard science, popular science, pseudo-science, and junk science involved A look at fluoride issues including dosage, cost, financial and funding interests, fluorosis, and problems of risk-cost-benefit analysis The back-and-forth drama between pro- and anti-fluoridation factions, with all its claims, counterclaims, insults, acrimony, and lawsuits Case studies of various cities and their experiences with municipal water fluoridation initiatives Fluorophobia and popular conspiracy theories involving fluoride The colorful characters in the debate including activists, scientists, magicians, and politicians A richly and considerately told tale of American science and public life, The Fluoride Wars offers an engrossing history to both interested general readers and specialists in public health, dentistry, policymaking, and related fields.

This book was released on 2010 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Dental fluorosis refers to changes in the appearance of tooth enamel that are caused by long-term ingestion of fluoride during the time teeth are forming. Studies conducted in the 1930s showed that the severity of tooth decay was lower and dental fluorosis was higher in areas with more fluoride in the drinking water. In response to these findings, community water fluoridation programs were developed to add fluoride to drinking water to reach an optimal level for preventing tooth decay, while limiting the chance of developing dental fluorosis. By the 1980s, studies in selected U.S. communities reported an increase in dental fluorosis, paralleling the expansion of water fluoridation and the increased availability of other sources of ingested fluoride, such as fluoride toothpaste (if swallowed) and fluoride supplements. This report describes the prevalence of dental fluorosis in the United States and changes in the prevalence and severity of dental fluorosis among adolescents between 1986-1987 and 1999-2004. Data from the National Health and Nutrition Examination Survey, 1999-2004 and the 1986-1987 National Survey of Oral Health in U.S. School Children." - p. 1.

This book was released on 2011-06-23 with total page 190 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together current concepts relating to the use of fluoride in dentistry. In contributions written by expert authors, data from this large and complex field have been assembled into a clear sequence and presented in a lucid fashion. The first section deals with the sources of fluoride intake and its metabolism, in order to fully understand fluoride toxicity and the importance of monitoring intake. The second section focuses in more detail on modes of fluoride application and the mechanisms by which this ion interacts with the oral environment to cause a remarkable reduction in dental caries. The role of fluoride in the prevention of dental erosion is also elucidated. The complex mechanisms by which fluoride exerts its effects are described with clarity and the entire text is accompanied by particularly useful illustrations.As a clear up-to-date summary of current thinking in the field, this book will be essential reading for research workers and postgraduate students. Established researchers and teachers in both clinical and basic sciences will find it to be a valuable addition to their libraries, and clinicians will be able to better evaluate the current scientific evidence on the advantages as well as the hazards of fluoride in dentistry.
