Training Dental Students in Dental Amalgam Condensation

In studying the characteristics of dental amalgam condensation by 36 dental students, it is concluded that : (1) A minimum force of 800 1 b/inch2 is required per condensation stroke in order for the condensation stroke to have any effect on the slow compressive strength test values as a predictor of marginal fracture.(2) A 30, 000 1 b/inch2 slow compressive strength test value may be derived from force utilization of 2, 000 1 b/inch2 per condensation stroke.
