AIM: The aim of this study was to determine whether an educational intervention delivered by a computer aided learning package improved the sensitivity and specificity of dentists' restorative treatment decisions. METHOD: The study was a randomised controlled study using a Solomon three-group design. Ninety-five dentists were randomly allocated to the three study groups. One group of dentists read the radiographs pre and post an educational intervention, a second group read the radiographs once, after the intervention, and a third group read the radiographs twice, but received no intervention. On each occasion the dentists read 24 surfaces on each of 15 radiographs and made 360 decisions on how certain they were about restoring the tooth surface. Comparisons of mean sensitivity, specificity and areas under ROC curves were made within and between the study groups. Kappa values were used to assess changes in the level of agreement between dentists. RESULTS: There were no significant changes in sensitivity, specificity or area under ROC curves caused by the intervention. There was no evidence that the level of agreement between the dentists improved after the intervention. CONCLUSION: A computer aided learning package had no effect on dentists' treatment decision-making behaviour.
The World Wide Web has become a source of information for clinicians and researchers about virtually every aspect of tuberculosis (TB). We provide information about TB-related Internet portal sites. We classify selected TB-related Web pages according to user needs. The questions that we address are as follows: (1) Where can I find scientific information about TB? (2) Where can I find epidemiologic data? (3) Where can I find literature for laypeople? (4) Where can I find recommendations, guidelines, and clinical decision-making algorithms for management of TB? (5) Where can I find research databases? (6) Where can I find research groups? (7) Where can I find resources for research, teaching, and training? (8) Where can I find information about regulatory action? The total number of TB-related Web pages is immense, their scope is vast, and their content is perpetually changing. Nonetheless, the sites identified here provide the reader with a manageable number of entry points to this increasingly important resource.
