  • Antibiotic prophylaxis, if 100% effective, likely prevents only a small number of cases of endocarditis; nevertheless, it is possible that rare cases are prevented. Weighing the potential benefits, potential adverse events, and costs associated with antibiotic prophylaxis, the expert committee of the American Heart Association has dramatically restricted the recommendations for antibiotic prophylaxis. Prophylactic antibiotics (Table 118-7) are advised only for those patients at highest risk for severe morbidity or death from endocarditis (Table 1188).

  • Infection control in health care continues to be the subject of intensive research and debate. Implementing safe and realistic infection control procedures requires the full compliance of the whole dental team. These procedures should be regularly monitored during clinical sessions and discussed at practice meetings. The individual practitioner must ensure that all members of the dental team understand and practice these procedures routinely. Every practice must have a written infection control policy, which is tailored to the routines of the individual practice and regularly updated.

  • Even though most psychological studies of motivated behavior have not paid much attention to the realm beyond control and rationality, our everyday lived experience reminds us of its importance. Consider how we describe, in both everyday and poetic language, our most deeply engag- ing experiences. We are “swept away” in a passionate relationship. We “fall” in love as if pulled by an inexorable force. Intense films or books grip us; great ideas seize us; laughter infects us. As new...

  • In the overall scheme of things, I am a Johnny-Come-Lately to equine dentistry. In 1993 I bought a small animal and equine practice in Meridian, Idaho. My equine clientele was somewhat sparse at first, so I could devote plenty of time to my examinations. I had floated horses’ teeth before, with the traditional long-straight and long-angled floats. Usually they had dull carbide chip blades on them because I didn’t know when they were supposed to be changed. Now that I owned my own clinic, the quality of work I produced mattered more than ever.

  • Children, especially those in groups, are more likely to get infectious diseases than are adults. As a childcare provider, you will be exposed to infectious diseases more frequently than will someone who has less contact with children. To protect yourself and children in your care, you need to know what immunizations you received as a child and whether you had certain childhood diseases. If you are not sure, your health care provider can test your blood to determine if you are immune to some of these diseases and can vaccinate you against those to which you are...

  • Periodontal disease is one of the major dental pathologies that affect human populations worldwide at high prevalence rates (Petersen, 2003). Periodontal diseases represents a family of heterogeneous chronic inflammatory lesions that involve the periodontium, a connective tissue protected by the epithelium, important to attach the teeth to the bone in the jaws and to support the teeth during function (Taylor, 2003).

  • A better understanding of the influence of tobacco smoke on the host response to periodontal infection has been the major concern in numerous studies whereas, limited research has been published aiming to identify the influence of tobacco smoke on the dental biofilm. Tobacco smoke has been shown to cause shifts in the microbial species that comprise dental plaque (Haffajee & Socransky 2001, Kamma et al. 1999, Shiloah et al. 2000, Umeda et al. 1998, van Winkelhoff et al. 2001, Zambon et al. 1996).

  • We planned the first edition of this book on a ‘need to know’ basis, its primary object being to provide students and medical and dental practitioners with the knowledge essential for an informed approach to the prevention and treatment of viral infections. We aimed also at supplying just enough basic virology to underpin the more practical aspects—clinical manifestations, epidemiology, pathogenesis, immune responses, and so forth. And not least, we tried our best to make the text as readable as is possible, given the highly technical nature of some of the material.

  • Dental Care of Medically Complex Patients Routine dental care (e.g., extraction, scaling and cleaning, tooth restoration, and root canal) is remarkably safe. The most common concerns regarding care of dental patients with medical disease are fear of excessive bleeding for patients on anticoagulants, infection of the heart valves and prosthetic devices from hematogenous seeding of oral flora, and cardiovascular complications resulting from vasopressors used with local anesthetics during dental treatment. Experience confirms that the risks of any of these complications are very low.

  • Endophthalmitis This occurs from bacterial, viral, fungal, or parasitic infection of the internal structures of the eye. It is usually acquired by hematogenous seeding from a remote site. Chronically ill, diabetic, or immunosuppressed patients, especially those with a history of indwelling IV catheters or positive blood cultures, are at greatest risk for endogenous endophthalmitis. Although most patients have ocular pain and injection, visual loss is sometimes the only symptom.

  • Orbital Cellulitis This causes pain, lid erythema, proptosis, conjunctival chemosis, restricted motility, decreased acuity, afferent pupillary defect, fever, and leukocytosis. It often arises from the paranasal sinuses, especially by contiguous spread of infection from the ethmoid sinus through the lamina papyracea of the medial orbit. A history of recent upper respiratory tract infection, chronic sinusitis, thick mucous secretions, or dental disease is significant in any patient with suspected orbital cellulitis. Blood cultures should be obtained, but they are usually negative.

  • Periodontal Disease Periodontal disease accounts for more tooth loss than caries, particularly in the elderly. Like dental caries, chronic infection of the gingiva and anchoring structures of the tooth begins with formation of bacterial plaque. The process begins invisibly above the gum line and in the gingival sulcus. Plaque, including mineralized plaque (calculus), is preventable by appropriate dental hygiene, including periodic professional cleaning.

  • Vertebral Osteomyelitis The vertebrae are the most common sites of hematogenous osteomyelitis in adults. Organisms reach the well-perfused vertebral body via spinal arteries and quickly spread from the end plate into the disk space and then to the adjacent vertebral body. Sources of bacteremia include the urinary tract (especially among men over age 50), dental abscesses, soft tissue infections, and contaminated IV lines, but the source of bacteremia is not evident in more than half of patients.

  • Dental problems such as caries, erosion, epulis, periodontal infection, loose teeth, and ill-fitting crowns, bridges, and dentures (prostheses) may have special significance during pregnancy (5;8;9;19;2325). Tooth decay is the result of repeated acid attacks on the tooth enamel. Any increase in tooth decay during pregnancy may be due to changes in diet and oral hygiene. Nausea and vomiting in pregnancy can cause extensive erosion. Pregnancy gingivitis is present in over 30 percent of pregnant women. At the time of labor and delivery, dislodged teeth or prostheses could cause complications....
