vii F O R E W O R D It is now 4 years since the seventh edition of Dental Management of the Medically Compromised Patient was published. The number of patients in this critically complex area of healthcare delivery continues to expand along with the scientific advances in etiology, patho- physiology, diagnosis, and treatment. The number of Americans over age 65, which now exceeds 15% of the population, is expected to increase by more than 20% within the next few decades. Thus the pool for such patients seeking and needing dental care grows. Further- more, as longevity increases, so do the number of dis- eases and conditions that disable individuals, converting them to compromised patients. With increasing longevity, and other factors such as obesity, poor diets, suboptimal exercise, new infections, as well as widespread use and abuse of drugs, the rising number of medically compromised patients will continue to grow. As a consequence, an ever increasing number of individuals with oral health problems will create demands and responsibilities on dental professionals with regards to services and standards of care. Education and readily available resource materials are essential to providing these services in an optimal and safe manner, and the thoroughly revised and updated eighth edition fills this role perfectly. A multitude of diseases have an impact on oral health- care services. Some examples follow. Cancer is an age- related disease that afflicts more than 1.5 million new patients each year in the United States. This in turn accounts for almost 25% of all deaths, and overall, is the second leading cause of death; in those under 85 years of age, cancer is the leading cause of death. Because of the number of new malignancies and the complica- tions caused by aggressive therapy to increase survival rates, dental services and information—for example, oral complications of cancer treatments and rehabilitation— take on significant importance. Furthermore, this is a global problem with new cases of cancer exceeding 12 million each year. Other examples of conditions that commonly affect dental-oral care are cardiovascular diseases, the number one killer of Americans, and diabetes. In Part 2, six chapters thoroughly cover all aspects of cardiovascular disease of interest for dental professionals. Diabetes (see Part 6, Chapter 14) is an exploding global problem with a profound effect on Americans, affecting more than 25 million with diagnosed diabetes, and an additional 12 million with undiagnosed diabetes. Diabetes has a large impact on dental health and care. It is the leading cause of end-stage renal disease and blindness among adults, and a major cause of heart disease and stroke. Diabetes is associated with obesity, poor diet, suboptimal physical activity, and aging. Projections estimate a possible dou- bling, or even tripling, in the coming decades if current trends continue. The list of medical diseases goes on, and underscores the need for current, reliable, and practical information to minimize or prevent potential problems related to general health, and ongoing oral-dental care. Knowledge of the pathophysiology of common medical diseases and conditions, along with the potential risks associated with some dental procedures and services, is essential. Interrelationships between oral and general health involve most organ systems. Some examples of medical- dental interaction relate to hematologic, autoimmune, and infectious diseases that strike both the young and the elderly. These conditions include blood dyscrasias, vesiculobullous inflammatory diseases, and many bacte- rial, viral, and fungal infections. Thus a very common issue is the proper recognition and management of oral manifestations, control of blood-borne pathogens, and avoidance of complications when providing dental treat- ment. Again, to appropriately meet this challenge, updated information in a concise and understandable format is essential. Because the majority of medically compromised patients need and/or seek oral healthcare, a working knowledge of the multitude of medically complex condi- tions is critical for dental professionals. This information will support and enable high standards for dental-oral healthcare delivery. This knowledge includes an under- standing of medical conditions and compromised states and is necessary to help prevent, minimize, and alert clinicians to possible adverse side effects potentially associated with procedures and drugs used in dentistry. An understanding will assist in formulating treatment plans that are safe and compatible with a patient’s medical status. Care of the medically compromised patient often is complicated, and requires specialists. However, occur- rence of compromised patients is so common that prac- titioners and students must know how to recognize and prevent problems associated with dental management, and to use consultations and referrals appropriately. This updated, revised, and expanded text recognizes and supplies this type of information with practical and organized overviews of diagnosis and management. This is accomplished in 30 well-organized and revised chapters by comprehensively covering diseases and con- ditions that lead to compromised states that affect a person’s well-being. The 30 chapters, are presented in 9 logical parts that enhance user-friendly utility. The mate- rial is supported by summary tables for easy access to information, figures, and graphs to supplement text, and
