Abstract

In order to investigate the change of stress-related hormones by dental occlusal reduction, we ground  molars in Sprague-Dawley (SD) rats and evaluated the effect on hormone levels. Thirteen and 18 weeks  after occlusal reduction, cortisol concentration was increased 2.75 and 2.17 fold respectively, whereas corticosterone  concentration was slightly elevated by 31.2% and 13.5%, respectively. Body weight was slightly  decreased, but feed and water intake, and blood chemistry were the same in the experimental group as  in the control group. Our results suggest that unilateral molar occlusal reduction may influence cortisol and  corticosterone levels and the endocrine system, leading to hormone imbalance through the body.
