The aim of this investigation was to establish possible correlation between parameters of occlusion and masticatory efficiency.
MATERIAL: Data were obtained in 15 healthy persons, 23-31 years of age (mean 25 years) with correct own dentition and without any disturbances of the stomatognathic system.
METHODS: Masticatory efficiency was measured using Optosil test modified by Slagter et al. after 20 and 80 cycles of chewing. It the time of chewing for 20 and 80 cycles of chewing was also established. Analysis of occlusion was made using T-scan II computerized system. Registration of occlusion was obtained before measuring masticatory efficiency after 20 and 80 cycles of
chewing. Statistical analysis was made and p<0.05 was statistically significant.
RESULTS: The time of chewing for 20 cycles and for 80 cycles respectively, mean 16 s +/- 3.0, and 55.6s +/- 9.5) reduction of particle size was about 1.5 mm. Time to maximal force ofpressure was shorter when chewing was longer. Maximal force of pressure for a unit of deflection indicator surface was higher after chewing. Share of sides of the teeth arch was about 59 per cent in all measurements.
Maximal force of pressure for a unit of deflection indicator surface was correlated with the time of chewing for 20 cycles of chewing (p <0.05). Correlation of time from the first contact of teeth to maximal force of pressure and maximal force of pressure for a unit of deflection indicator surface was statistically significant for 80 cycles .
There was no evident correlation between values of X50 and occlusal parameters established in computerizedanalysis.
CONCLUSION: Chewing ability is correla ted with occlusion although this relationship is not significant.
