Throughout the preparation of this report, the creative effort was conducted with great independence. The ideas expressed herein are not necessarily those of, nor endorsed by, the American Dental Association. This document is a vital tool for dentistry as the profession grows and evolves in these beginning years of the 21st century. The information and recommendations in this report provide the tools we need to mold, paint and shape the strong future that all of us want for our profession and certainly for our patients. As we take up this task, we should be mindful of the legacy developed by the actions of those who came before us. Our strong public image came not from outside forces but from dentists–all giving, sacrificing and working for the good of the public and the profession. Together, we can determine the wisest steps to take and then commit ourselves to the actions necessary to strengthen dental education, research, practice, access to care for the underserved, our role in governmental affairs, and other key aspects of this profession. It is equally difficult to discern the problems that will confront our profession. The 2001 Future of Dentistry report attempts to create a vision of challenges that are likely to emerge in the coming years. The report is based upon reasonable evaluation and interpretation of current information and observable trends. This project, while commissioned by the American Dental Association, is not a policy document of the organization. It has been designed to reach out to all parties interested in the betterment of health through- out the world and, more specifically, to those who are able to contribute to improving the delivery of dental care in order to achieve the optimal oral health of the public. The many who contributed to this report––giving enormously of their time and expertise––hope that future generations will look back on it as a landmark document. It represents their commitment to excellence and an understanding that the profession and its partners must set aside parochial agendas to fulfill their social responsibility. The authors want the report to be read and believe firmly that all who do so will develop a bet- ter understanding of the issues facing the dental profession in its pursuit of excellence in serving the public. It is meant to stimulate thoughts and actions that will move the dental profession forward into the new century. In order for it to have the lasting impact, the report must become a living document that can be amended and redesigned as circumstances evolve. It is clear that in this complex and ever- changing world, isolation is not a viable option. Plans for the future must take into account that advances in the diagnosis and treatment of oral disease are being made throughout the world. Sophisticated informational technology will be emerging to benefit both the public and dental professionals. Instead, interaction can occur almost instantly among persons separated by continents. Political will, social responsibility and the willingness to set aside cultural differences are also necessary.

These drugs may also interfere with in- tracellular localization of certain oncogenes and thereby reduce the incidence of some cancers trusted avanafil 50mg erectile dysfunction doctors in nc. Mechanism (1) Nicotinic acid can exert cholesterol- and triglyceride-lowering effects at high concentra- tions (nicotinamide cannot do this) best avanafil 100 mg erectile dysfunction treatment mayo clinic. Adverse effects (1) Nicotinic acid commonly produces flushing and an itching or burning feeling in the skin, which may reduce compliance. This is mediated by prostaglandin and histamine release and can be diminished by taking aspirin 30 minutes before taking nicotinic acid. Gemfibrozil (Lopid) (1) Gemfibrozil is a fibrate that is more effective than fenofibrate in some circumstances and has some unique biologic activities. Cholesterol is absorbed from the small intestine by a process that includes specific transporters that have not been completely characterized. Ezetimibe appears to block one or more of these choles- terol transporters, reducing cholesterol absorption. Ezetimibe used alone produces a reduction in plasma cholesterol of about 18% and about a 10% decline in triglyceride levels. When combined with a statin, reductions in plasma cho- lesterol as high as 72% have been reported in clinical trials. Ezetimibe appears to be well tolerated, with the most common adverse effects being fatigue, abdominal pain, and diarrhea. These agents include cholestyramine (Questran), colestipol (Colestid), and colesevelam (WelChol) a.

Yet apart from this discount avanafil 200mg with mastercard impotence at 50, there is an increasing in- terest being taken in medical generic avanafil 100 mg mastercard erectile dysfunction pills cheap, scientific and philosophical texts, not just because of their intellectual contents but also from the point of view of linguistics, literary studies, discourse analysis, narratology, ethnography of literature (orality and literacy), rhetoric and communication studies. This is related to a growing scholarly awareness of the communicative and com- petitive nature of Greek medicine and science. Greek doctors, philosophers, astronomers and mathematicians had to impress their audiences, to per- suade them of their competence and authority, to attract customers and to reassure them that they were much better off with them than with their rivals. Medical, scientific and philosophical texts functioned in a specific setting, with a particular audience and purpose, and served as vehicles not only for the transmission of ideas but also for the assertion of power and authority. These developments have given rise to a whole new field of studies and questions regarding the ways in which knowledge was expressed and com- municated in the ancient world: the modes of verbal expression, technical idioms, stylistic registers and literary genres that were available to people who laid a claim to knowledge (healers, scientists, philosophers) in order to convey their views to their fellows, colleagues and their wider audiences; the rhetorical strategies they employed in order to make their ideas intel- ligible, acceptable, or even fashionable; the circumstances in which they Introduction 31 had to present their ideas, and the audio-visual means (writing facilities, diagrams, opportunities for live demonstration) they had at their disposal; the interests and the expectations of their audiences, and the ways in which these influenced the actual form of their writings; and the respects in which ‘scientific’, or ‘technical’, or ‘expert’ language or ‘discourse’ differed from ‘ordinary’ and ‘literary’ language and ‘discourse’. After many years of considerable neglect, the last two decades have thus seen a significant increase in attention being given to the forms of ancient scientific writing, especially among students of the Hippocratic Corpus, but also, for example, on Latin medical literature, with some studies focusing on ‘strictly’ linguistic and textual characteristics, while others have attempted to relate such characteristics to the wider context in which the texts were produced. First, general trends in the study of rhetoric and discourse analysis, in particular the study of ‘non-literary’ texts such as advertisements, legal proceedings, minutes of meetings, political pamphlets and medical reports, the study of rhetoric and persuasive strategies in apparently ‘neutral’ scien- tific writings, and the development of genre categories based on function rather than form have led to a growing awareness among classicists that even such seemingly ‘unartistic’, non-presumptuous prose writings as the extant works of Aristotle, the Elements of Euclid and the ‘notebook-like’ Hippocratic Epidemics do have a structure which deserves to be studied in its own right, if only because they have set certain standards for the emergence and the subsequent development of the genre of the scientific treatise (‘tractatus’) in Western literature. It is clear, for example, to any student of Aristotle that, however impersonal the tone of his works may be and however careless the structure of his argument may appear, his writings nonetheless contain a hidden but undeniable rhetoric aimed at making the reader agree with his conclusions, for example in the subtle balance be- tween confident explanation and seemingly genuine uncertainty, resulting in a careful alternation of dogmatic statements and exploratory suggestions. The study of these formal characteristics has further been enriched by a growing appreciation of the role of non-literal, or even non-verbal as- pects of communication (and conversely, the non-communicative aspects of language). Aesthetics of reception, ethnography of literature and studies in orality and literacy have enhanced our awareness of the importance of 34 For more detailed discussion and bibliographical references see van der Eijk (1997), from which the following paragraphs are excerpted. Here, again, discourse studies and ethnogra- phy of literature have provided useful instruments of research, for example D. Hymes’ analysis of the ‘speech event’ into a number of components that can, not without some irony, be listed according to the initial letters of the word speaking: setting (time, place, and other circumstances), scene (e. A recent German collection of articles on ‘Wissensvermittlung’ (‘transmission of knowledge’) in the ancient world gives an impression of the kind of questions and answers envisaged from such an integrated approach. At this point, a most fortunate connection can be perceived between linguistically inspired approaches within classical philology and the recent surge of a ‘contextual’ approach in the history of science, whereby the text is seen as an instrument for scientists and practising doctors to use to define 35 Hymes (1972) 58ff. Introduction 33 and assert themselves, to establish the position of their profession and to gain authority and power. Again, the variations the Hippocratic Corpus displays with regard to the use of rhetoric (not only the well-known Gorgianic figures of speech but also argumentative techniques, analogies, metaphors, etc. Such an awareness has led to greater caution in the establish- ment of doctrinal ‘parallels’ or ‘inconsistencies’ between different works of the same author, which would have been used as evidence of a development in doctrine or even as a basis for declaring a work genuine or spurious. Such caution is inspired by a consideration of differences in genesis (single or multiple authorship), status (e. Thus it has been attempted to relate varying degrees of philosophical sophistication in some of Plato’s dialogues to differences between the au- diences for whom they were intended (as indicated by the contribution of the interlocutors),41 and something similar has been attempted with regard to differences in method – and to some extent also doctrine – between the three treatises on ethics preserved in the Aristotelian Corpus. Similar formal characteristics of medical and philosophical texts affecting the interpretation or evaluation of particular passages and their relation to other passages in the same work or in other works lie in the field of ‘genre’, where, again, the sheer variety in forms of expression is particularly striking. When, how and for what purposes prose came to be used for the transmission of knowledge in the late sixth century bce and why some writers (such as Parmenides and Empedocles, or in later times Aratus and Nicander) preferred to write in verse when prose was available as an alternative, is not in all cases easy to say. Yet the Hippocratic Corpus provides opportunities to gain some idea of the process of text-production and genre- formation, and one can argue that medicine has played a decisive role in the formation of scientific literature. The variety of forms of writing referred to above is manifest already within the Hippocratic Corpus itself. Airs, Waters, Places; On the Sacred Disease ; On the Nature of Man), show a degree of care and elaboration on account of which they deserve a much more prominent place than they now occupy in chapters on prose in Greek literature. Here we do have a large body of texts generally agreed to be by one author (although there 41 Rowe (1992). Yet any general account of Aristotle’s philosophy is bound to begin with a discussion of the problems posed by the form and status of his writings. Do they represent the ‘lecture notes’ written by Aristotle himself on the basis of which he presented his oral teaching? Or are they to be taken as the ‘minutes’ or ‘verbatims’ of his oral teaching as written down by his pupils? Certainly, some characteristics of his works may be interpreted as evidence of oral presentation;44 and with some (parts) of his works it is not easy to imagine how they might have been understood without additional oral elucidation – although this may be a case of our underestimating the abilities of his then audience and an extrapolation of our own difficulties in understanding his work. However, other parts of his work are certainly far too elaborate to assume such a procedure.
