The first group, group A, (test group) received 50µL / Kg of green tea dissolved in distilled water, the 2nd group, group B, received distilled water.

The last group, group C, (control group) received no injection.

Blood samples were taken at a time interval of (1, 3, 42, 72,168) hours for biochemical analysis of vitamin C and Malondialdehyde (MDA). Results : Study showed there was a highly significant increase in mean concentration of serum vitamin C three hours after sulcular injection with 5%green tea extract (P < 0.01),while a significant decrease in mean concentration of serum MDA after injection at the same time with the same extract (P < 0.05). Conclusion : Green tea injected into sulcular had beneficial antioxidant effect, thus green tea can be used safely and successfully in periodontal treatment.
