Fig. 2From: HSP70 mRNA expression by cells of the epithelial rest of Malassez due to mechanical forces in vitroHSP70 mRNA expression at 3 h after different mechanical stimuli. Type 3 shows a significantly higher expression of HSP70 mRNA than the control, as well as type 1 and cover type 2. There was no significant difference among the control, type 1 and type 2, although both type 1 and type 2 tended to be higher than the control group. **p < 0.01Back to article page
