...[Enter the REPORT TITLE here] Charter College Abstract In oral health care, the number and range of laser-based technologies have expanded enormously over the past two decades. The scope of this paper is to alert the dental professional to the extent, application, and responsibilities associated with safety when using lasers designed for use in dentistry. By far, the majority of laser instruments are within the private (nonhospital) clinic setting. Laser use extends from those procedures of a diagnostic or nonsurgical (bio stimulatory or photochemical) nature, to more powerful devices that are used in surgical procedures. Low-powered lasers may deliver energy of a few millijoules, whereas surgical lasers may have pulsed emission modes capable of peak power delivery in excess of 1,000 Watts. Laser radiation can be dangerous, because it is concentrated and powerful. This paper draws upon the standards outlined by the International Electro-technical Commission Keywords: ANSI: American National Standards Institute. A not-for-profit organization, founded in 1918, that oversees the administration and coordination of the United States private sector voluntary standardization system.

...LASERS IN PREPROSTHETIC SURGERY LASER is an acronym for light amplification of stimulated emission of radiation. Laser application in maxillofacial surgery practice covers control of leukoplakia, oral malignancy, preprosthetic or periodontal surgery, temporomandibular joint, uvulopalatostomy, and cosmetic procedures. Clinical lasers are of two types; soft lasers are essentially an aid to healing with relatively few rigorous studies available to support their use. Surgical hard lasers, however, can cut both hard and soft tissues and replace the scalpel and drill in many areas. From initial experiments with the ruby laser most clinicians are using argon, CO2 and now Nd:YAG systems. Both the CO2 and Nd:YAG lasers can be used for intraoral soft tissue surgeries. The advantages of lasers include a relatively bloodless surgical and postsurgical course, minimal swelling and scarring, coagulation, vaporization, and cutting, minimal or no suturing, reduction in surgical time, and, in a majority of cases, much less or no postsurgical pain. CO2 LASER Since its development in the early 1960s, the CO2 laser has been rapidly introduced into medical research and almost every dental and medical surgical specialty. In dental surgery it is mainly used for oral soft tissue applications. High-power lasers are one of the greatest technologies advances in dentistry field. In 1989 the first laser specifically designed for use in dentistry, a carbon dioxide (CO2) laser was introduced. The CO2...

...Case Reports in Pediatric Dentistry Edited by Evert van Amerongen Maddelon de Jong-Lenters Luc Marks Jaap Veerkamp Quintessence Publishing Co Ltd London, Berlin, Chicago, Tokyo, Barcelona, Beijing, Istanbul, Milan, Moscow, New Delhi, Paris, Prague, São Paulo, Seoul and Warsaw Foreword It is essential that clinicians treating children have a high degree of awareness and knowledge of a wide range of oral conditions to optimize the dental care for their patients. Some of these conditions are commonly encountered whereas others are rather infrequent, thus giving the practicing dentist limited experience to build up diagnostic and treatment skills. The latter may concern, for example, different types of developmental disturbances such as hypodontia or disturbances of mineralization of dental hard tissues, as well as pathologic conditions in oral mucosa and bone. Of great interest in increasing knowledge and clinical experiences is the case reports/presentations, which, unfortunately to a limited extent, are published in pediatric scientific journals. This book has been produced in an attempt to overcome this and to give dentists involved in clinical dentistry for children an opportunity to a systematic approach in continuing education in diagnostics, indications, treatment, and follow-up of cases that could be seen in their own practices. In this book, 16 cases treated by experienced clinicians are presented, including case history, examination, diagnosis, indications for...

Copyright © 2007, Ivey Management Services Version: (A) 2007-03-12 One Friday afternoon in September 2005, Dr. Nicholas Burns, a sole practitioner dentist from Busby, Ontario, was driving home from a continuing education course on gum disease. At the course, he had overheard two dentists discussing Waterlase®, the new dental laser that allowed dentists to perform dental treatments without anaesthesia. One of the two was purchasing this technology. Burns had seen an increasing number of journal articles about the laser in recent years. Although he had wondered whether he should acquire one, he had held off because his instincts told him that the laser might not be the magic wand many made it out to be. Furthermore, Burns was particular about the type of technology he purchased for his practice. He wanted to ensure that it would be economically profitable or would provide him with a piece of technology that was becoming standard in dentistry. As Burns pulled...

...radiation which can penetrate many non-polar, non-conducting materials such as clothing, paper, masonry or plastic. They can penetrate fog and clouds. Their wavelength corresponds revealingly with bio molecular vibrations. Terahertz radiation, also known as t-rays, has wavelength of 3-100 cm-1. Terahertz radiation was discovered in 1896. Unless they're at a temperature of absolute zero (−273.16°C), all objects, animate and inanimate, give off terahertz radiation (called T-rays), the heat from molecular vibrations. No one knew how to make T-rays bright enough to actually use in the everyday world. Attempts with semiconductors produced only wimpy T-rays, 1/2,000th of a watt at most. One way to make terahertz radiation is based on an ultra-fast laser. The THz band were initially being referred as “terahertz gap” due to two reasons. Firstly, there were not any proper and affordable signal sources, which are capable of transmitting signals in those frequencies, and secondly the neighbour frequencies around this frequency range are being used in electronics and optical technologies. Recently, with the...

...transmit light between the two ends of the fiber.[1] The field of applied science and engineering concerned with the design and application of optical fibers is known as fiber optics. Optical fibers are widely used in fiber-optic communications, which permits transmission over longer distances and at higher bandwidths (data rates) than other forms of communication. Fibers are used instead of metal wires because signals travel along them with less loss and are also immune toelectromagnetic interference. Fibers are also used for illumination, and are wrapped in bundles so they can be used to carry images, thus allowing viewing in tight spaces. Specially designed fibers are used for a variety of other applications, including sensors and fiber lasers. ------------------------------------------------- History Fiber optics, though used extensively in the modern world, is a fairly simple and old technology. Guiding of light by refraction, the principle that makes fiber optics possible, was first demonstrated by Daniel Colladon and Jacques Babinet in Paris in the early 1840s. John Tyndall included a demonstration of it in his public lectures in London a dozen years later.[2] Tyndall also wrote about the property of total internal reflection in an introductory book about the nature of light in 1870: "When the light passes from air into water, the refracted ray is bent towards the perpendicular...

The molecules are held together by covalent bonds that are branched, linear, or networked to form the polymeric material (Carraher & Charles, 2). While most polymers have carbon as their backbone, others have silicon as the main element holding the polymer (Carraher & Charles, 2). . The history of polymerization The science of polymerisation began way back in the 19th century where alumina-silica glass and phosphoric acid was widely applied to fill dentures (Carraher & Charles, 2). . However, the compounds had very poor mechanical properties and high solubility. This meant that they were not particularly suited in sensitive applications such as dentistry. Later in the mid 20th century, acrylic resins replaced the silica compounds as the only synthetic material (Carraher & Charles, 2). These comprised of polymethylmethacrylate compounds that had higher polymerization shrinkage than the former (Carraher & Charles, 2). Despite their superiority, bonding was...

...[pic] Reverse Engineering a New Trend in Manufacturing [pic] Authors T.Dhamotharakumar* N.S.Ramesh* dhamotharan007@gmail.com nsrmechanical@gmail.com * Under graduate Student, K.S.R. College of Engineering, Tiruchengode Department of Mechanical Engineering [pic] Abstract With the significant capital investment in new equipment being placed into out years, more systems need to be maintained in their present condition for longer periods of time. There are often gaps in the technical support information needed to maintain a system built from older designs using outmoded or updated techniques or materials. In some situations, designers give a shape to their ideas by using clay, plaster, wood, or foam rubber, but a CAD model is needed to enable the manufacturing of the part. As products become more organic in shape, designing in CAD may be challenging or impossible. There is no guarantee that the CAD model will be acceptably close to the sculpted model. Reverse engineering provides a solution to this problem because the physical model is the source of information for the CAD model. This is also referred to as the part-to-CAD process. "Reverse Engineering is the process of taking a finished product and reconstructing design data in a format from which new parts or molds can be produced."-The Society of Manufacturing Engineers Key Words: Reverse Engineering, CAD, Modeling and manufacturing. ...

LEU Additive manufacturing: technology, applications and research needs © Higher Education Press and Springer-Verlag Berlin Heidelberg 2013 Abstract Additive manufacturing (AM) technology has been researched and developed for more than 20 years. Rather than removing materials, AM processes make three-dimensional parts directly from CAD models by adding materials layer by layer, offering the beneficial ability to build parts with geometric and material complexities that could not be produced by subtractive manufacturing processes. Through intensive research over the past two decades, significant progress has been made in the development and commercialization of new and innovative AM processes, as well as numerous practical applications in aerospace, automotive, biomedical, energy and other fields. This paper reviews the main processes, materials and applications of the current AM technology and presents future research needs for this technology. Keywords additive manufacturing (AM), AM processes, AM materials, AM applications 1 Introduction The ASTM F42 Technical Committee defines additive manufacturing (AM) as the “process of joining materials to make objects from three-dimensional (3D) model data, usually layer upon layer, as opposed to subtractive manufacturing methodologies” [1]. It is also known as additive fabrication, additive processes, direct digital...

...Electromagnetic radiation is usually characterized by wavelength and frequency or photon energy. The term wavelength refers to a distance in a line of advance of a wave from any point to a like point on the next wave; it corresponds to the distance traveled by the wave during one cycle. A wavelength is usually measured in angstroms or nanometers (nm). The International Commission on Illumination (CIE) has divided the UV spectrum into three wavelength bands, primarily due to biological effects. The 315-400 nm wavelength band is designated as UV-A. 280-315 nm is designated as UV-B, and 100-280 nm as UV-C. Wavelengths below 180 nm are of little practical biological significance since the atmosphere readily absorbs them. Sources of UV-A are used for dentistry and tanning, UVB is used for fade testing and photocuring of plastics, and UV-C (100-280 nm) is used for germicidal purposes. All wavelengths less than 320 nm are actinic, meaning they are capable of causing chemical reactions. The mechanism of the germicidal effect involves these chemical reactions and so effectiveness varies by composition of the target organism in addition to physical variables. tochemical response to the skin normally...
