Eosinophilic granuloma is said to be the most benign disorder of the triad commonly known as histiocytosis X. There has been, and still is, confusion about the terminology describing this entity. This article reviews the literature on histiocytosis X, with particular emphasis on eosinophilic granuloma and its oral manifestations. The case of a 22-month-old male child with an eosinophilic granuloma of the right mandible is presented. The diagnostic and treatment methods are reviewed and discussed. During the 4 years that the case has been followed there has been progressive healing of the lesion, but other manifestations of the disease process and of the surgical treatment have become evident. The need for close dental as well as medical follow-up in cases involving the dental structures is stressed.
Although many schools use scores on the Dental Admission Test (DAT) to evaluate applicants, the association of these scores with students' performance on Part I of the National Board Dental Examinations (NBDE) has not been recently evaluated. In this study, the hypothesis that the DAT scores would be a significant predictor of Part I of the NBDE scores was tested. We analyzed by multiple regression the scores on both examinations for the 114 students matriculating in the University of Mississippi School of Dentistry in 1992Dentistry in , 1993Dentistry in , 1994Dentistry in , and 1995. The results indicate that DAT reading comprehension was a statistically significant predictor (p value less than or equal to 0.05) of all four subtests of Part I of the NBDE. The DAT biology and organic chemistry scores were statistically significant predictors of NBDE biochemistry-physiology, and the DAT quantitative analysis score was a statistically significant predictor of NBDE dental anatomy and occlusion. DAT perceptual ability and general chemistry were not significant predictors.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
