Changes in Zinc Concentration in Oral Environment as a Risk Factor of Periodontal Disease

Abstract

The Zinc (Zn) concentration was determined from salivary gland of Wistar King A (WKA) rats. The salibary glands are divided in to sub-lingual, sub-mandible and parotis. The Zn concentration was determined within 15-60 minutes of 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.
