In studying the characteristics of the dental amalgam restorations of 64 dental students, it is concluded that :
(1) sporadic use of the microscope (20×) does not help to improve the performance of dental amalgam restorations;
(2) it is hypothesized that continued use of the microscope during work performance may result in improved work performance; and
(3) it is hypothesized that tactile and kinesthetic rather than visual abilities are the dominating factors in dental psychomotor performance.
