"As an essential nutrient, zinc play important roles in many biological functions. The activity of zinc as co-factor enzymes is supporting by the activity of copper and iron. The study was observed the changes of level activity of zinc, copper and iron concentration in sub lingual gland saliva, sub mandible gland saliva and parotids gland saliva The concentration of zinc, copper and iron were determinant by using the X-Ray Fluorescent. The concentration of zinc and iron were significantly increase (p<0.005) in sub lingual within 60 min restraint stress, and copper was significantly decrease (p
In conclusion, the changes in trace elements of zinc, copper and iron in the salivary gland of sub lingual gland saliva, sub mandible gland saliva, and parotids gland saliva may be closely related to the processes of enzymes activations induced by mild physiology stimuli and that the metabolisms of these metals are differently regulated according to each functional role in the salivary gland system."

"The dynamic of Zinc (Zn) concentration was determined in saliva and blood serum related to periodontal treatment need of student Faculty of Dentistry. The Zn concentration was determined by using atomic absorption spectrometer, and questionnaire was used to measure stress condition and CPITN index was examined by using the standard hand instruments and WHO probe. Almost of concentration of Zn in saliva and blood serum were decrease significantly (p<0,001 & p<0.0S)) in stress condition. While CPITN index was increase significantly in stress condition (p<0.000I). These results suggest that Zn is linked to oral saliva ecosystem under physiological stimuli, and than Zn accumulates in the salivary gland during saliva enzyme activities. This condition supported the occur of periodontal disease."

"The Zinc (Zn) concentration was determined from salivary gland of Wistar King A (WKA) rats. The salivary glands are divided in to sub-lingual, sub-mandible and parotis. The Zn concentration was determined within 15-60 minutes of restraint stress. Concentration of Zn in sub-mandible, parotis and sub-Lingual glands was significantly higher (p<0.001) than in the control group. Further more at Zinc concentration in sub-mandible gland at 30 min restraint stress was increase (p<0.001), and decrease significantly at 49 min by restraint stress. By the way, Zn concentration in parotis gland was increase significantly (p<0.0001) after 60 min restraint stress. The results suggest that Zn is linked to oral saliva under physiological stimuli, and that Zn accumulates in the salivary gland during salivary enzyme activity."
