To Assess The Relationship between Masticatory Performance and Jaw Movement with the Use of a Colour - Changeable Chewing Gum
Journal Title: International Journal of Contemporary Medical Research - Year 2018, Vol 5, Issue 4
Abstract
Introduction: Both subjective and objective way of evaluation can be used to assess masticatory performance. This study was carried out to find out the association between the masticatory performance and the mandibular movements determined with the use of a colour-changeable chewing gum. Material and methods: The study was done on 50 dentate adults (25 men,25 women) with a mean age of 28 years. The subjects were told to chew the gum for a specified number of chewing strokes (20, 40,60,80,120 or 160 strokes). No instructions were given as to the selection of chewing side. Then a colorimeter was used to determine L*,a* and b* values (CIE-L*a*b* color system”). After this, the difference in the two colors on the CIE-L*a*b* color space was calculated with the formula. Opto-electric system with six degrees of freedom was then used to record the mandibular movements relating the amplitude, velocity, duration and angle for each cycle with a mean value for 10 cycles in total. Results: The results calculated by the stepwise multiple regression analysis stated that 18% of variation in DE60 was there. Conclusion: The results were indicative of increased speed and lower angles of approach to intercuspation to be associated with color changes in the gum.
