This book was released on 2016 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: Prior to the advent of bonded orthodontic appliances each tooth was fitted with a band made from stainless steel. Traditionally they were cemented to the tooth with a zinc phosphate cement. This acted more as a luting agent then adding to the actual adherence of the band to the tooth. In addition, often times the cement would wash out and upon the band removal white spot lesions and or carious lesions were present. The development of glass monomer cements had a traumatic improvement over both the adhesion to the tooth and a diminishing of white spot lesions in part due to the release of fluoride. Since the advent of the acid-etch technique and the bonding of orthodontic brackets directly to the enamel various bonding adhesives were developed. The first and most popular bonding resins were chemical curing bonding systems. The general class of self-adhesive and/or self-etching orthodontic adhesives are of several types, including resin-modified cements, such as resin-modified glass ionomer cements, that exhibit self-adhesive properties to enamel, as well as self-etching primers that combine the conditioning and priming agents into one acidic, polymerizable composition for application to the tooth surface, and do not require separate etching and rinsing steps. Not only do resin modified glass ionomers have the benefit of chemically bonding to a clean and un-etched enamel surface, but these self-adhesive cements also release significant and continuous levels of fluoride ion. Recently investigators have explored adding antimicrobial agents in addition to fluoride in orthodontic adhesives. One such approach has been the addition of ZnO powder, a known compound with anti-microbial properties, to an orthodontic resin modified glass ionomer adhesive. It should also be noted that zinc ions and compounds have been shown to positively influence enamel remineralization and enhance apatite formation. The objective of this research is to evaluate the effect of the addition of an antimicrobial agent, zinc oxide powder, on selected mechanical properties of a resin modified glass ionomer orthodontic adhesive. Methods: A resin modified glass ionomer (Fuji Ortho LC), in its two-component, powder/liquid format were utilized in this study. Control specimens, according to manufacturer's directions for use, were prepared for both diametral tensile and microhardness testing with be prepared. Using the powder component provided in the marketed product; powder blends containing both 10 and 20 percent Zinc Oxide (by weight) will be added to the RMGI powder, and thoroughly mixed and blended to create a uniform powder blend. The mechanical testing will be performed on 8-10 disc specimens, approximately 6.2 mm diameter by 3.1 mm in height, using a standardized mixing and molds for each material. The specimens will be tested using the Instron 5569 testing machine at a crosshead speed of 0.75 mm/minute for DTS until failure occurs. Data was recorded in Newton's (N) force. The microhardness testing was performed on 12 disc specimens, approximately 6.2 mm diameter by 3.1 mm in height, using a standardized mixing and molds for each material. A CSM microindentation testing device was used to measure theVickers microhardness. The surface morphological evaluation of the specimens both control and experimental will be examined at 50 X magnification for comparison of surface characteristics and morphology. One-way ANOVA for comparison of time- and material-specific mean Vickers microhardness values and post hoc pair-wise comparisons was employed to assess statistically significant differences in the mean values (p

This book was released on 2003-06-30 with total page 836 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
