Book Description
The abrasive characteristics of six (6) brands of toothpastes on Enamel and Dentin material were assessed. Human teeth were sliced to expose the dentin surface and then polished using 3 æm and 0.25 æm diamond paste. The outside surface of the tooth (after slicing) was used "as is" for the enamel surface testing. The surface smoothness was evaluated prior to testing using a surface profiler and averaging four (4) to five (5) readings across the surface for each sample. The tooth slices were then embedded into the acrylic plate surface by routing out an area with a dental drill and using polymethylmethacrylate (PMMA) to adhere the teeth to the plate. An acrylic abrasion machine was used to brush each sample for 3000 strokes with each of the toothpastes being tested. At least three (3) samples of each material were used for each paste. The same type of medium stiffness brush was used for each test. The surface smoothness was then re-assessed using the surface profiler again averaging four (4) to five (5) readings across the surface. The data was statistically analyzed and ranked by abrasiveness.

Book Description
Indispensable for dentists, dental students and community dental programs With the mass-marketed introduction of fluoride in toothpaste in the 1950s, toothbrushing with paste became indispensable for good oral health. Both the industry and the dental profession had a shared interest in advocating the widespread correct use of good quality toothpaste. This publication starts with a general introduction on the purpose, history and composition of toothpaste. The following chapters deal with the clinical evidence of its effectiveness in caries prevention, reducing and preventing plaque, gin-givitis, halitosis, and calculus formation, facilitating removal and prevention of extrinsic stain, and preventing dentine hypersensitivity and erosion. Later chapters provide valuable information on the abrasiveness of the pastes, the substantivity of active ingredients in the oral cavity and the possible models to study the effectiveness of the pastes when full-scale clinical trials are not possible. The final chapter focuses on the frequency of toothbrushing and post-brushing rinsing behavior. The book provides indispensable information for dentists, dental students and community dental programs on whether toothpastes can be recommended to patients for specific aims and how to use them to obtain the best effect.

Book Description
The 11th edition of this leading reference is an outstanding, scientifically based source of information in the field of dental materials science. It presents up-to-date information on materials that are used in the dental office and laboratory every day, emphasizing practical, clinical use, as well as the physical, chemical, and biological properties of materials. Extensive new clinical photographs in this edition illustrate the topics, and color plates are integrated close to related concepts as they're discussed in each chapter. A new glossary of key terms found at the beginning of every chapter defines terms in the appropriate context of the chapter's discussion. Also in this edition, critical thinking questions throughout the book stimulate the readers' curiosity on specific topics, test their existing knowledge, and heighten their awareness of important or controversial subjects. Content outlines at the beginning of each chapter provide a quick reference for specific topics. The roles played by key organizations in ensuring the safety and efficacy of dental materials and devices are described - such as the American Dental Association, the U.S. Food and Drug Administration, the International Organization for Standardization, and the Fédération Dentaire Internationale. Up-to-date Selected Readings are presented at the end of each chapter to direct readers to supplemental literature on each topic. Numerous boxes and tables throughout summarize and illustrate key concepts and compare characteristics and properties of various dental materials. Distinguished contributors lend their credibility and experience to the text. Content has been completely updated to include information on the most current dental materials available. Glossaries at the beginning of each chapter define key terms used within the context of that chapter. Revised artwork gives this edition a fresh look, with high-quality illustrations and clinical photos to aid in the visualization of materials and procedures described. Reorganization and consolidation of chapters into four major book parts presents the material in a more efficient way: Part I describes the principles of materials science that control the performance of dental materials in dental laboratories, research laboratories, student dental clinics, public health clinics, and private practice clinics. Part II focuses on impression materials, gypsum products, dental waxes, casting investments and procedures, and finishing and polishing abrasives and procedures. Part III provides an updated scientific and applied description of the composition, manipulation principles, properties, and clinical performance of bonded restorations, restorative resins, dental cements, dental amalgams, and direct-filling golds. Part IV presents a basic and applied description of materials that are processed in a laboratory or dental clinic. Critical thinking questions appear in every chapter to stimulate thinking and classroom discussion. The overall design has been improved to provide a more visually appealing format.

Book Description
The focus of Handbook for Cleaning/Decontamination of Surfaces lies on cleaning and decontamination of surfaces and solid matter, hard as well as soft. Bringing together in a 2-volume reference source: - current knowledge of the physico-chemical fundamentals underlying the cleaning process; - the different needs for cleaning and how these needs are met by various types of cleaning processes and cleaning agents, including novel approaches; - how to test that cleaning has taken place and to what extent; - the effects of cleaning on the environment; - future trends in cleaning and decontamination, for example the idea of changing surfaces, to hinder the absorbance of dirt and thus make cleaning easier.A brief introduction is given to the legal demands concerning the environment and a historical background, in terms of development of detergents, from soaps to the modern sophisticated formulations. Bactericides, their use and the environmental demands on them are covered. Thorough discussions of mechanisms for cleaning are given in several chapters, both general basic concepts and special cases like particle cleaning and cleaning using microemulsion concepts.* General understanding of how cleaning works, function of ingredients and formulations * Overview of environmental issues and demands from the society in the area * Gives basic formulas for cleaning preparations in most areas

Book Description
Tooth sensitivity, or dentin hypersensitivity, has a high prevalence among the general population and is a very common cause of visits to the dentist. This concise, easy-to-read guide provides the clinician with the most important information required for the correct diagnosis and effective management of dentin hypersensitivity. After discussion of theories regarding the underlying mechanisms, predisposing medical and dental conditions are reviewed. The route to an accurate diagnosis, based on determination of the precise cause, is then explained. A range of potential treatment approaches and their applications are discussed, including dentin blocking agents, nerve desensitization, restorative approaches and periodontal surgery. Preventive, at-home and in-office treatment modalities are all described and future treatments are also considered. Helpful flowcharts are included that will facilitate decision making.
