Masticatory Side Change and Masticatory Function.

Mastication Disorder Clinical Trial

Official title:
Relationship Between the Frequency of Masticatory Side Switches and Aspects of Masticatory Function.

Clinical Trial Summary

The primary objective of this study is to establish the effect of the frequency of masticatory side switches on masticatory performance. We also want to know the effect of the frequency of masticatory side switches on the masticatory rhythm. Twenty-eight healthy volunteers will undertake masticatory tests, following a series of instructions given at the moment. These volunteers will take a re-test in two-weeks time. The sequence of these tests will be randomized in such a way that, each participant will initially perform an established sequence of "freestyle, only-right, and only-left" masticatory tests, and then will carry out one of the 6 possible combinations of "A1, A3, and A5". These tests will be recorded on video to assess, on slow playback, the change of the chewing side, and the masticatory rhythm.Masticatory performance will be determined by sieving the silicone particles.

Clinical Trial Description

This crossover intervention study aims to assess the effect of the degree of alternance of the chewing side on various aspects of masticatory function, including masticatory performance and rhythm. Twenty-eight volunteers will take part, recruited for convenience, among friends and relatives of the teachers and students of the Degree of Dentistry of the Faculty of Medicine and Health Sciences of the University of Barcelona. These individuals will perform masticatory tests and, after a period of two weeks, will repeat them as a re-test. Each participant will perform 6 tests, each consisting of 5 assays, chewing a small latex bag containing a few silicone tablets (2 g) during 20 masticatory cycles. One test involves freestyle mastication in which the participant will be asked to chew the latex bag naturally. Two tests involve chewing the bag unilaterally (i.e., right-hand side in one and left-hand side in the other) and the order of their assays will be varied. For the last three tests, the participant will change the chewing side 1 (A1), 3 (A3), or 5 (A5) times respectively; the sequence of the assays will be randomized. The masticatory performance will be determined by the "median particle size" (MPS), and the masticatory rhythm will be assessed through the masticatory frequency as the ratio of masticatory cycle number to masticatory time. The control variables will include age and sex. ;
