Masticatory Stresses and their Relation to Dental Caries

Research in gnathodynamics, dormant for some time after the days of G. V. Black, is showing distinct signs of resurrection. Klaffenbach (1), Waugh (2), Brekhus (3), and Brekhus, Armstrong and Simon (4) have recently reported on their experiments in measuring masticatory stresses by means of the gnathodynamometer. In 1936, the author (5) published the results of his experiments with this valuable instrument. Recently, through the courtesy of Dr. L. M. Waugh, I was able to use the gnathodynamometer of the School of Dentistry of the University of Minnesota.
