To show the peculiarities of the circadian organization
of chewing system in connection to the identified circadian type,
one hundred practically healthy persons 21‑35 years were subdi‑
vided into three groups using test by Ostberg; the results of their
electromyography, gnatodynamometry, and the chewing efficiency
estimation have been compared. Based on the dynamics of the ab‑
solute values and the formation of relations between the studied pa‑
rameters it was shown for the optimum functioning of chewing to
be about 12:00 at persons with morning type, to be between 12:00
and 16:00 at «middle» type, and closely to each other. Whereas the
similar time for the persons with evening type was revealed closer
to 20:00. These differences were recommended like necessary to
take into account in planning the time of orthopaedic dental ma‑
