title: [The demonstration of a relation between premolar force and molar force within the limits of a simplified approach to masticatory system functioning].
abstract: The purpose of this study is to show the existence of a correlation between the premolar and molar clenching forces obtained during a voluntary clenching exercise. The study concerned 32 volunteers aged 21 to 28 with no manducatory problems. The forces were obtained using a device with four Kiowa traducers arranged in a complete Wheatstone bridge. The analysis of the results obtained showed that there was a positive correlation between maximum molar and premolar. The analysis also shows that three results are a direct application of the theory of momentum. This enables us to propose a simple biophysical model to explain the functioning of the masticatory system.
