Infectious diseases and the dental office.

Dentists and other health care workers have long been concerned about a variety of infectious agents that may be transmitted within the dental setting. In recent years there has also been widespread concern among the general public. Many infectious diseases, including HIV, hepatitis, tuberculosis and syphilis, are important both because of their potential transmissibility and because the first manifestations of the disease may appear in the oral cavity. A knowledge of these diseases will allow the practitioner to recognize associated lesions and also to take appropriate steps to minimize the risk of transmission in the dental office.

Self-inflicted oral trauma: report of case.

Self-inflicted oral trauma is often encountered in patients who lack cerebral control over the masticatory cycle. Many factors must be considered in treatment, and a variety of appliances may be fabricated to prevent injury to oral structures. This case report documents the use of a soft acrylic appliance in treatment of a comatose patient who showed ruminatory reflex chewing.

Hepatitis: still a concern?

Although some forms of viral hepatitis were identified more than 50 years ago, hepatitis continues to have an impact on the practice of dentistry. Possible transmission in the dental setting, management of the chronically ill, and legal issues related to treatment of infectious patients combine to emphasize that hepatitis is still an important issue for dental health care workers. Currently, 7 viral forms are recognized. Those with predominantly enteral modes of transmission--including HAV, HEV, and HFV--are of minor concern in the dental environment. HBV, the most infectious blood-borne pathogen, has been largely controlled in this country by vaccination and the use of universal precautions. HDV is an incomplete virus that has HBV infection as a prerequisite. HCV is of great concern today for several reasons. A high percentage of HCV infections results in chronic disease. Most cases remain asymptomatic for an extended period of time, and many have no identifiable risk factors. Currently, no vaccination is available for HCV. Patients infected with HCV present a management challenge, because they may ultimately develop serious liver dysfunction. In fact, HCV infection is presently the most common reason for liver transplantation. By understanding the various forms of viral hepatitis and following recommended infection control and vaccination protocols, the dental healthcare worker can treat infected patients in a manner that is safe for both patients and dental health care workers.

The effects of an interactive instructional strategy for enhancing reading comprehension and content area learning for students with learning disabilities.

This study investigated the effectiveness of an interactive vocabulary instructional strategy, semantic-feature analysis (SFA), on the content area text comprehension of adolescents with learning disabilities. Prior to reading a social studies text, students in resource classes either completed a relationship chart as part of the SFA condition or used the dictionary to write definitions and sentences as part of the contrast condition. Passage comprehension was measured on a multiple-choice test consisting of two types of items, vocabulary and conceptual. Comprehension was measured immediately following teaching and again 6 months after teaching. Prior knowledge for the content of the passage served as a covariate. Results indicated that students in the SFA instructional condition had significantly greater measured comprehension immediately following and 6 months after initial teaching. These results are discussed in relation to concept-driven, interactive strategies for teaching content and facilitating text comprehension.
