The composition of unstimulated whole saliva of healthy dental students.

The purpose of this study was to determine the unstimulated whole saliva biochemical parameters in healthy dental students of Tehran University of Medical Sciences (TUMS) living in the students' dormitory with a mean age of 22 years. Five ml whole saliva samples were obtained by expectoration. The saliva composition was measured by a spectrophotometer and affiliated kits. The data was analyzed through the student's unpaired t-test using the SPSS program. In the male students (n=50) the mean concentrations of glucose (mmol/l), inorganic phosphate (mmol/l), total protein (mg/ml), magnesium (mmol/l), chloride (mmol/l), and calcium (mmol/l) were 0.75+/-0.44, 1.52+/-0.63, 6.69+/-2.89, 1.27+/-0.45, 27.60+/-11.06, and 2.17+/-0.76, respectively. In the female students (n=50) they were 0.73+/-0.47, 1.58+/-0.63, 7.26+/-3.78, 1.37+/-0.44, 30.42+/-12.74, and 1.87+/-0.78, respectively. There were no significant differences between the whole saliva values in male and female students.
