Masticatory stresses have been recorded in 4 subjects using a resistance wire strain gauge apparatus accommodated in inlays in lower molars. The stresses have been expressed in kilograms per square millimeter of occlusal surface used for recording.
In 1 of the 4 subjects, the total pressure exerted per chewing sequence is strikingly greater than in the other subjects with all 3 food materials tested.
No consistent pattern of treatment emerges as far as the pressures are concerned, even with biscuit which was from the same batch for the whole investigation. When the numbers of recorded chewing movements are examined, however, the variation from subject to subject is much less marked with biscuit than with the other materials.
