The machine completed the etching, silanating, and adhesive cementing, and then conventional porcelain-polishing procedures were used to complete the process. The newer CEREC II system can create full-coverage ceramic crowns (Foerster 2). Beyond the greater technological ease, using such machines reduces the risk of tooth fracture between visits. Reduced treatment time and visits for impressions and provisional restorations reduces costs to the patient, and also to the military (Foerster 4). Most attractively for the military: "Finally, teeth can be restored without the services of a dental laboratory. This reduces the overall cost of the restoration and permits the restoration of teeth in remote locations where laboratory services may not be readily available" (Foerster.3).
The value of such technology is not limited to the military, of course. Dentists working in clinical settings without laboratory services with such technology can still conduct such restorative work, once the initial outlay for the technology is made. Dentists with patients on limited or no insurance plans, by reducing dental visits, can also keep...
However, as the article makes clear, this cost reduction does not result in compromised care, rather it results in better care for the patient, and also eliminates the uncomfortable period during visits, before the procedure is completed. The bonding of the teeth is stronger than with previous methods (Foerster 2). "Besides the increased strength and durability, the coefficient of thermal expansion and the elastic modulus of this material are also much closer to those of tooth structure" (Foerster 2). There seem to be few downsides to the use of this technology, other than the initial expense of the machine, and the training required for personnel to operate such machines, but once this is accomplished, over time, the machines will essentially pay for themselves.

In 2002 the crime lab in the state of Mississippi found that the semen in the victim's body belonged to two different men and neither of them was Kennedy Brewer. Balko concludes by stating: "Forensic scandals have been troublingly common of late, with phony experts, fake results, and incompetent testing recently uncovered in Virginia, Maryland, Kansas, Illinois, and Texas, to name just a few. Courts need to take a
Theory of the self-monitored students and CSCL Another popular theory associated with the concept of CSCL is the self-monitored student s (Benbunan-Fich, 2002 ). Benbunan-Fich (2002 ) in their study give students the chance to explore and discover their abilities and then guide through ways that they can polish them. In the case of CSCL, the students realize that they will need guidelines and principles in order to attain a set objective and
Translational medicine is a new discipline, which covers studies on basic science, on human investigations, non-human investigations, and translational research (Mankoff et al. 2004). Basic science studies address the biological effects of medicines on human beings. Studies on humans discover the biology of disease and serve as foundation for developing therapies. Non-human or non-clinical studies advance therapies for clinical use or use in human disease. And translational research refers to
Others include delays in data accessibility, albeit shorter delays and the continued need for source data verification (Donovan, 2007). Other obstacles have occurred in the developing of mobile healthcare applications. These have included mobile device limitations, wireless networking problems, infrastructure constraints, security concerns, and user distrust (Keng and Shen, 2006). A third problem that has been encountered is that of a lack of education on not only the importance of the
Lack of accountability, transparency and integrity, ineffectiveness, inefficiency and unresponsiveness to human development remain problematic (UNDP). Poverty remains endemic in most Gulf States with health care and opportunities for quality education poor or unavailable, degraded habitats including urban pollution and poor soil conditions from inappropriate farming practices. Social safety nets are also entirely inadequate and all form part of the nexus of poverty that is widely prevalent in Gulf countries.
Arizona State University (ASU) is a leading metropolitan research international institution in the United States that is committed to excellence in teaching, research, and public service. Established in Tempe in 1885 by a legislative act, ASU was initially formed as a teachers college. The core of the Tempe campus was a 20-acre cow pasture donated by leading citizens who desired an institution to educate public school teachers and offer instruction
