In a quasi-experimental design the "experimental" group (n = 6) received discrimination training and self-evaluation exercises on four waxing projects and four handpiece projects over 13 hours. An equivalent "conventional" group (n = 7) received verbal feedback with models on seven waxing projects over 13 hours. Both groups took a posttest using plastic(More)
All 86 first year dental students in a Conservative Restorations course completed five sets of instructional tasks. Tasks followed a discrimination learning paradigm, a sequence based on the principal that recognition skills are a prerequisite for production skills. Recognition skill measures and production quality measures were collected for pre- and(More)
15-beta-hydroxy cyproterone acetate could be identified by thin layer chromatography, mass spectrum, NMR and IR spectrum as a major unconjugated metabolite of cyproterone acetate in plasma and urine of dog, monkey and man. This metabolite has been found to interferein the Mattingly method for the determination of 11-hydroxy-corticosteroids which suggests,(More)
Students contorted to achieve direct vision indicate that training of mirror skills is absent or ineffective. Training referenced in the literature is not described or amounts to practice using a mirror to perform a psychomotor task often marginally related to dental procedures. No complete task analysis of mirror use is reported. In this study, the authors(More)
Multi-antibiotic resistant Gram-positive cocci, which include Staphylococcus aureus, the coagulase-negative staphylococcal group, Enterococcus faecalis and Enterococcus faecium, and other streptococci, represent emerging pathogens especially in the setting of the immunocompromised, hospitalized patients, in particular when surgery, invasive procedures, or(More)
