Green tea is reported to have various physiological activities, including antioxidative, anticancer, hypolipidemic, hypoglycemic, hypotensive and antibacterial effects. Green tea also contains antiviral components that prevent influenza infection. Experimental studies have also revealed that tea extract prevents influenza virus infection.
Green Tea Consumption: Brewed green tea contains an average of 126.6 mg total catechins and 77.8 mg EGCG per 100 ml as consumed, on the basis of 1 g leaf/100 mL infusion. Consequently, each 240 mL serving of brewed green tea may provide an estimated 304 mg total catechins, with 187 mg EGCG (Epigallocatechingallate).
The effects of daily consuming of green tea on clinical criteria in Periodontitis was conducted:
1.Thirty patients with chronic periodontitis were randomly divided into control and experimental groups after scaling and root planning (SRP).
2.Experimental group consumed green tea herbal (2g tea leaf/day) for 6 weeks and the control group received no intervention.
3.Clinical indices were measured before and 6 weeks after the intervention, and compared for each groups by non-parametric Wilcoxon test and between two groups by Man-Witheny test.
4.Significance level of the test was considered at 95%.
5.The results showed that probing depth (PD) and bleeding index (BI) reduced significantly in both groups before and after SRP, this reduction in the intervention group was higher than the control group (P=0.003 and 0.031, respectively).
6.On the other hand, reducing the amount of plaque index (PI) despite being significant in each group, was not significant between the two groups (P=0.135).
Conclusions: According to the results of this study, daily consumption of green tea herbal can have a positive impact on the treatment of periodontal diseases and can be applied as a supplement for improving the effects of phase I periodontal therapy.
