Practice Guideline Guideline
Prevention of bacterial endocarditis: recommendations by the American Heart Association.
To update recommendations issued by the American Heart Association last published in 1990 for the prevention of bacterial endocarditis in individuals at risk for this disease. ⋯ Major changes in the updated recommendations include the following: (1) emphasis that most cases of endocarditis are not attributable to an invasive procedure; (2) cardiac conditions are stratified into high-, moderate- and negligible-risk categories based on potential outcome if endocarditis develops; (3) procedures that may cause bacteremia and for which prophylaxis is recommended are more clearly specified; (4) an algorithm was developed to more clearly define when prophylaxis is recommended for patients with mitral valve prolapse; (5) for oral or dental procedures the initial amoxicillin dose is reduced to 2 g, a follow-up antibiotic dose is no longer recommended, erythromycin is no longer recommended for penicillin-allergic individuals, but clindamycin and other alternatives are offered.

The international normalized ratio, or INR, was introduced in 1983 by the World Health Organization, or WHO, Committee on Biological Standards to more accurately assess patients receiving anticoagulation therapy. The INR mandates the universal standardization of prothrombin time. This article describes the method used to calculate INR, as well as its clinical relevance to the practice of dentistry.

Randomized Controlled Trial Multicenter Study Clinical Trial
Analgesic efficacy and safety of an intraoral lidocaine patch.
The effectiveness of intraoral II-docaine patches was tested by asking participants to rate the pain experienced after insertions of a 25-gauge needle. Needlesticks were performed at baseline and at various time points after patch placement. ⋯ Drug-related side effects were minimal and venous blood levels of lidocaine were low, averaging 10 to 14 times less than those achieved with a typical injection of lidocaine plus epinephrine. The authors conclude that the lidocaine patches used in this study are effective and safe in reducing needle insertion pain in adults.

Recurrent aphthous ulcers, or RAU--also called canker sores--are among the oral mucosal conditions that dentists and physicians see most commonly in their patients. Several systemic conditions are associated with oral aphthouslike ulcers, and aphthae themselves often are mistaken for recrudescent oral herpes simplex virus, or HSV, infections. This article will review RAU, describe systemic conditions associated with aphthous-like ulcerations and discuss the differences between RAU and recrudescent oral HSV infections.
