Book Description
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.

Book Description
"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.

Book Description
This very well-received book, now in its second edition, equips the radiologist with the information needed in order to diagnose internal medicine disorders and their complications from the radiological perspective. It offers an easy-to-consult tool that documents the most common and most important radiological signs of a wide range of diseases, across diverse specialties, with the aid of an excellent gallery of images and illustrations. Compared with the first edition, numerous additions and updates have been made, with coverage of additional disorders and inclusion of many new images. Entirely new chapters focus on occupational medicine and toxicology imaging, chiropractic medicine, and energy and quantum medicine. Internal Medicine – An Illustrated Radiological Guide puts the radiologist in the internal medicine physician’s shoes. It teaches radiologists how to think in terms of disease progression and complications, explains where to look for and to image these complications, and identifies the best modalities for reaching a diagnosis. It will also benefit internal medicine physicians by clarifying the help that radiology can offer them and assisting in the choice of investigation for diagnostic confirmation.

Book Description
This intermediate textbook on oral epidemiology is designed to meet the needs of advanced students in the fields of Dentistry and Oral Health and dentists in the early stages of their career. Readers will find detailed information on the epidemiology of individual diseases and disorders and on hot topics and methods in oral health research. The extensive first part of the book explores the international epidemiological literature regarding a wide range of conditions, from dental caries and periodontal diseases to halitosis and malocclusions. In each case, the prevalence, disease-specific measures, and associated factors are identified. Attention is then focused on cutting-edge research topics in oral epidemiology, such as the intriguing mechanisms linking oral diseases and chronic general diseases, life course epidemiology, and the role of socioeconomic determinants of oral health. The final part of the book is devoted to description of the epidemiological methods and tools applied in the field of oral health. Here, the coverage includes validation of questionnaires, data collection and data analyses, and systematic reviews and meta-analyses.

Book Description
Endemic fluorosis is caused by excessive intake of fluorine in drinking water, air, food, tea and other media in a specific natural environment for a long time, which involves at least 25 countries, such as China, India, Vietnam, Iran, Egypt, Mexico, Argentina and influences more than 200 million of population. China and India are the countries with the most extensive endemic fluorosis and the most serious damages. There are three main intake sources of endemic fluorosis, e.g., drinking water, coal-burning pollution and drinking tea. Coal-burning type of endemic fluorosis was established in Guizhou Province of China in 1970’s. The residents in the areas used indoor stoves with no flue to burn coals with high content of fluoride to bake grains in the autumn and heat in the winter. This results in excessive intake of fluorine and then leads chronic poisoning. It has been confirmed that 13 provinces of China with 34.3 million of population are influenced by this type of fluorosis with severe injuries to most organs of human body. The content of this book covers the epidemiology, pathological changes, molecular pathogenesis and clinical treatments of the disease. This book is a suitable reference for the researchers and graduate students in this field, which is helpful to improve the understanding of this disease and to take preventive measures.
