1. Students changed their body position 32% more often than instructors during amalgam condensation. 2. Experienced instructors used 38% fewer strokes than students to condense the amalgam. 3. On the average, instructors used 65% less time per condensation stroke than students. This was not due to ability to move the instrument more quickly, since both(More)
From a study of 72 dental students during amalgam restoration using four training methods (psychomotor, mental, psychomotor and mental, and conventional)--one method for each 18 students--the following conclusions are drawn: (1) It is economically feasible to develop and utilize self-paced instructions without the aid of instructors for the acquisition of(More)
A predictive model of overall quality of performance is presented which might assist both dental students and dental faculty by increasing the reliability of clinical and laboratory evaluations. Training effectiveness can be improved by identification of those restorative skills which contribute most to the quality rating of restoration.
