Keywords: biofluids, saliva, non-invasive samples, crystalisation, stress resistibility, ovulation time


Aim: The aim of the study was to reveal the relationship between stress resistibility levels and
saliva microcrystallization and to investigate whether menstruation phase has infl uence on the
saliva microcrystalisation.
Methods: The group of obseravtion included 26 healthly women aged 19-30. Facies of saliva
were investigated by microscopic analysis of hydration of drops of mixed saliva (Havriluk, 2014).
For estimation of stress resistibility levels questionnaire created by ISMA (International stress
management association, 2011) was used. To reveal the infl uence of menstrual phase on the
microcrystalisation saliva facies were collected from women every three days during the menstrual
Results: It was discovered that the absence of microcrystalisation (4th type) was most
often seen among people with low stress resistibility. What about relationship between saliva
microcrystalisation and menstrual cycle there was the trend of high incidence of 1st and 2nd
types during the ovulation.
Conclusions: Saliva investigation of microcrystallization types can be used as an additional
method of estimation of stress and as a method of the approximate detection of the ovulation, so
it can be used for planning pregnancy. Method of evaluation of saliva microcrystallization types is
a helpful tool for detection of characteristic of hormonal cycle and can be used for patients with
secondary amenorrhea, surgical menopause and prescription of hormonal replacement treatment
or specifi c treatment (e.g. chemotherapy).
