With the recent upswing in professional ethical misconduct, a comprehensive reeducation in ethical concepts is imperative. This text represents my understanding of the ethical principles from early Greek society to today's society. It clearly outlines the logical historical beginnings of ethical thought, gives students a greater appreciation for the validity of established ethical concepts, provides for a greater understanding of the various aspects of professional ethics and legal issues, and presents workable mechanisms for the prevention, management, and resolution of ethical and/or legal situations in the realm of dentistry. While other texts on this subject appear to be written to appeal primarily to one audience (i.e. dentists or dental hygienists); this text will be valuable asset to dental students, dental hygiene students, practicing dentists, and practicing dental hygienists. By utilizing a simple, 'to the point' approach to dental ethics and legal issues; I feel that anyone who reads my textbook will benefit from my apporach to the subject matter. The specific questions that this book will address are listed as follows: What is ethics? Where and how did ethics begin? How are ethics, religion, and the law related as guides for our actions? Are the concepts of Aristotle, Aquinas, and others valid for modern-day professional applications? How do ethical principles relate to the dental profession? What are some of the consequences for violations of ethical principles? What happens when ethical violations become legal problems, and what types of civil and/or criminal issues may practitioners face in today's society? How can practitioners minimize, manage and resolve the various ethical and/or legal situations they may encounter in modern dentistry and dental hygiene?
