Book Description
Lists and definitions of the most common pathologies likely to be encountered during specific procedures helps you understand the whole patient and produce radiographs that will make diagnosis easier for the physician.Labeled radiographs identify key radiographic anatomy and landmarks to help you determine if you have captured the correct diagnostic information on your images. "Evaluation Criteria" for each projection provide standards for evaluating the quality of each radiograph and help you produce the highest quality images."Clinical Indications" sections explain why a projection is needed or what pathology is demonstrated to give you a better understanding of the reasoning behind each projection. Increased emphasis on digital radiography keeps you up to date with the most recent advances in technology.Completely updated content offers expanded coverage of important concepts such as, digital imaging systems, updated CT information and AART exam requirements. More CT procedures with related sectional images, especially for areas such as skull and facial bones, reflect the shift in the field from conventional radiography to CT.Updated art visually demonstrates the latest concepts and procedures with approximately 500 new positioning photos and 150 updated radiographic images. Additional critique images provide valuable experience analyzing images to prepare you to evaluate your own images in the practice environment.Updated "Technique" and "Dose" boxes reflect the higher kV now recommended for computed and digital radiography."Imaging Wisely" program information from ASRT provides protocols to minimize radiation exposure during digital procedures.The latest standards for computed radiography and digital radiography (CR/DR) from the American Association of Physicists in Medicine ensures you are current with today s procedures and modalities."

Publisher: Elsevier Health Sciences
ISBN: 0323078230
Category : Medical
Languages : en
Pages : 513
Book Description
This book provides essential knowledge for creating treatment plans for adult dental patients. Treatment planning strategies are presented to help with balancing the ideal with the practical, with emphasis placed on the central role of the patient — whose needs should drive the treatment planning process. The focus is on planning of treatment, not on the comprehensive details of every treatment modality in dentistry. CD-ROM bound into book presents five cases of varying difficulty with interactive exercises that allow users to plan treatment. What's the Evidence? boxes link clinical decision-making and treatment planning strategies to current research. In Clinical Practice boxes highlight specific clinical situations faced by the general dentist. Review Questions and Suggested Projects, located at the end of each chapter, summarize and reinforce important concepts presented in the book. Key Terms and Glossary highlights the terms that are most important to the reader. Suggested Readings lists included at the end of most chapters provide supplemental resources. Chapter on Treatment Planning for Smokers and Patients with Oral Cancer addresses the dentist's role in managing patients with oral cancer, recognizing oral cancer and differential diagnosis of oral lesions, planning treatment for patients undergoing cancer therapy, and smoking cessation strategies. Chapter on Treatment Planning for the Special Care/Special Needs Patient examines the role of the general dentist in the management of patients with a variety of conditions including physical handicaps, mental handicaps, head trauma, hemophilia, and patients' needs before, during, or after major surgery. Chapter on Treatment Planning for the Alcohol and Substance Abuser discusses the challenges of treating this patient population, as well as how to recognize the problem, delivery of care, scope of treatment, and behavioral/compliance issues. Expanded content on Ethical and Legal Issues in Treatment Planning reflects new accreditation guidelines. Dental Team Focus boxes highlight the relevance of chapter content to the dental team. Ethics Topics boxes emphasize the ethical topics found within each chapter. International Tooth Numbering is listed alongside the U.S. tooth numbers in examples and illustrations.
