The Smile Gap


Book Description

As recently as fifty years ago most people expected to lose their teeth as they aged. Few children benefited from braces to straighten their teeth, and cosmetic procedures to change the appearance of smiles were largely unknown. Today, many Canadians enjoy straight, white teeth and far more of them are keeping their teeth for the entirety of their lives. Yet these advances have not reached everyone. The Smile Gap examines the enormous improvements that have taken place over the past century. The use of fluorides, emphasis on toothbrushing, the rise of cosmetic dentistry, and better access to dental care have had a profound effect on the oral health and beauty of Canadians. Yet while the introduction of employer-provided dental insurance in the 1970s has allowed for regular visits to the dentist for many people, a significant number of Canadians still lack access to good oral health care, especially disabled Canadians, those on social assistance, the working poor, the elderly, and new immigrants. At the same time, an attractive smile has become increasingly important in the workplace and in relationships. People with damaged and missing teeth are at a substantial disadvantage, not just because of the pain and suffering caused by poor oral health, but because we live in a society that prizes good teeth and warm smiles. The first history of oral health in Canada, The Smile Gap reveals that despite the gains made, too many Canadians go without any dental care, with damaging consequences for their oral health, general physical health, and self-image. To complete our health care system, it is time to close the gap.

A Systematic Review of Public Water Fluoridation


Book Description

The aim of this systematic review has been to assess the evidence on the positive and negative effects of population wide drinking water fluoridation strategies to prevent caries. 214 studies met full inclusion criteria for one or more of the objectives. The best available evidence suggests that fluoridation of drinking water supplies does reduce caries prevalence. This review presents a summary of the best available and most reliable evidence on the safety and efficacy of water fluoridation. Given the level of interest surrounding the issue of public water fluoridation, it is surprising to find that little high quality research has been undertaken. As such, this review should provide both researchers and commissioners of research with an overview of the methodological limitations of previous search conducted in this area. The evidence of a benefit of a reduction in caries should be considered together with the increased prevalence of dental fluorosis. The research evidence is of insufficient quality to allow confident statements about other potential harms or whether there is an impact on social inequalities.




Teledentistry


Book Description

Teledentistry is of growing interest to the healthcare world. Over the last few years, momentum is growing in research and service in Teledentistry - mostly carried out by tertiary medical institutes across the world. While Teledentistry is advanced in some sub-specialties, it has high potential to receive more attention from general communities, dentists, dental hygienists, physicians, nurses, researchers and students. For the first time, this book will present essential knowledge from experts in this field. They will discuss the current status of technology and service in various Telledentistry sub specialties and its future implications. Written by experts from around the globe, (i.e., from USA, Europe, Australia and Asia), this book presents technical issues and clinical applications. It includes collective experiences from dental service providers in different parts of the world practicing a wide range of Teledentistry applications. This book lays the foundations for the globalization of Teledentistry procedures, making it possible for dental service to be delivered anywhere in the world.




Helgoland


Book Description

Named a Best Book of 2021 by the Financial Times and a Best Science Book of 2021 by The Guardian “Rovelli is a genius and an amazing communicator… This is the place where science comes to life.” ―Neil Gaiman “One of the warmest, most elegant and most lucid interpreters to the laity of the dazzling enigmas of his discipline...[a] momentous book” ―John Banville, The Wall Street Journal A startling new look at quantum theory, from the New York Times bestselling author of Seven Brief Lessons on Physics, The Order of Time, and Anaximander. One of the world's most renowned theoretical physicists, Carlo Rovelli has entranced millions of readers with his singular perspective on the cosmos. In Helgoland, he examines the enduring enigma of quantum theory. The quantum world Rovelli describes is as beautiful as it is unnerving. Helgoland is a treeless island in the North Sea where the twenty-three-year-old Werner Heisenberg made the crucial breakthrough for the creation of quantum mechanics, setting off a century of scientific revolution. Full of alarming ideas (ghost waves, distant objects that seem to be magically connected, cats that appear both dead and alive), quantum physics has led to countless discoveries and technological advancements. Today our understanding of the world is based on this theory, yet it is still profoundly mysterious. As scientists and philosophers continue to fiercely debate the meaning of the theory, Rovelli argues that its most unsettling contradictions can be explained by seeing the world as fundamentally made of relationships rather than substances. We and everything around us exist only in our interactions with one another. This bold idea suggests new directions for thinking about the structure of reality and even the nature of consciousness. Rovelli makes learning about quantum mechanics an almost psychedelic experience. Shifting our perspective once again, he takes us on a riveting journey through the universe so we can better comprehend our place in it.
