The activity of salivary glands and the chemical and physical properties of saliva, especially in some illnesses in which the activity of salivary glands and the chemical and physical properties alter, sometimes have severe effects on sedimentation and tooth decay. Long-standing investigations have shown the relationship between salivary gland activity and saliva composition in dental carries. Many modern techniques have been employed to measure important elements in saliva. The major elements in saliva include sodium, potassium, calcium, magnesium, chlorine, phosphorus, iodine, and fluorine. It should be pointed out that the amount of minerals changes when the diet changes. The major constituent of saliva is water with a density of 1.007 g/cm[sup 3] in which 0.6% is solid, 0.3% organic material and 0.3% inorganic material. In addition to other effects, the acidity (pH) of saliva has a strong effect on tooth sedimentation. Type of work, degree of stress, and mental condition affect salivary gland activity. When the acidity of salivary fluid in the mouth and consequently over the teeth drops, sedimentation increases. In this paper, the results of trace element measurement in saliva are presented.
