A total of 2,905 pedicle measurements were made from T1-L5. Measurements were made from spinal computerized tomography (CT) scan examinations and individual vertebral specimen roentgenograms. Parameters considered were the pedicle isthmus width in the transverse and sagittal planes, pedicle angles in the transverse and sagittal planes, and the depth to the(More)
Poor prediction of psychomotor performance in dentistry using traditional admissions tests and prior academic performance, as well as the serious consequences of poor performance for both students and faculty, suggest that better predictors are needed. Two tests of waxing skill were incorporated into the first semester freshman dental anatomy course and(More)
Significant properties are those aspects of a digital record that must be preserved over time in order for it to remain accessible and meaningful. The development of a formal, or canonical a method to define significant properties requires some understanding of the digital record, the different types of properties that may be encountered and the appropriate(More)
STUDY DESIGN Change in lumbar lordosis was measured in patients that had undergone posterolateral lumbar fusions using transpedicular instrumentation. The biomechanical effects of postoperative lumbar malalignment were measured in cadaveric specimens. OBJECTIVES To determine the extent of postoperative lumbar sagittal malalignment caused by an(More)
Profundus tendon lacerations were repaired in the central toes of 216 chickens, and the digits were either immobilized in a cast or allowed immediate constrained motion in a tethering splint. The effect of digital motion on the early phases of tendon healing was investigated by comparing the rupture strengths of the two groups during the first 40 days after(More)
For the process of question-guided problem-solving to work successfully, several conditions must exist: 1) presence of valid and reliable criteria for evaluating product (DO) and performance (DP), 2) development of learning resources such as life-sized examples, 3) training sessions in the application of criteria and use of the process for both faculty and(More)
Most dental school instructors struggle to develop course evaluation criteria that can effectively be applied as valid and reliable learning instruments. Vague and unreliable learning assessments often lead to increased dissatisfaction among both faculty and students. Students complain about the "lack of faculty calibration," and faculty are often unable to(More)
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)
