Clostridium difficile-induced diarrhea and colitis are common complications of therapeutic courses of antibiotics in the hospital setting. We report a case of Clostridium difficile colitis following antibiotic prophylaxis for endocarditis prior to dental procedures in the community setting. The infection necessitated hospital admission and a prolonged hospital stay. Dental practitioners must be aware of the significance of the disease and the risk associated with antibiotics, whether they are used for prophylaxis or treatment.

Smokeless tobacco use has increased rapidly in North America. This form of tobacco use has many oral effects including leukoplakia, oral cancer, loss of periodontal support (recession), and staining of teeth and composite restorations. Systemic effects such as nicotine dependence, transient hypertension and cardiovascular disease may also result from smokeless tobacco use. This paper aims to guide dental practitioners in identifying oral lesions that occur due to the use of smokeless tobacco and also offer guidelines on how to counsel patients who express a desire to stop using smokeless tobacco products.

Review Case Reports
Bilateral dentigerous cysts--report of an unusual case and review of the literature.
Dentigerous cysts are the most common developmental cysts of the jaws, most frequently associated with impacted mandibular third molar teeth. Bilateral dentigerous cysts are rare and occur typically in association with a developmental syndrome. The reported occurrence of bilateral dentigerous cysts in the absence of a syndrome is rare and, to date, only 11 cases have been described. Here, we report a case of bilateral nonsyndromic, dentigerous cysts and review the literature for this unusual finding.
