Abstract

Aim

Smoking is a significant source of oxidative stress. Also, the disruption in equilibrium between free-oxygen radicals and antioxidants plays a pivotal role in the progression of periodontal inflammation. Green tea with antioxidant potential might have an effect on periodontal disease. This study evaluated the periodontal status in different groups of smokers compared with nonsmokers and investigates the association with salivary antioxidant levels after a period of green tea consumption.

Materials and methods

In this interventional study, 60 healthy males, including 20 light and 20 heavy cigarette smokers and 20 control nonsmokers, participated. Periodontal status was determined by the Community Periodontal Index of Treatment Needs (CPITN) at the beginning of the study. All participants were asked to consume a total of two cups of green tea (4 gm) per day. Total antioxidant capacity (TAC) of saliva was measured at baseline and after 21 days. Statistical evaluation was done by Statistical Package for the Social Sciences (SPSS) version 21 software.

Results

The Pearson correlation coefficient between CPITN and salivary TAC showed significant correlation in light and heavy smokers (p = 0.001 and p = 0.003 respectively). Changes in salivary TAC from baseline to day 21, after green tea consumption, in subjects with CPITN ≤ 18 were 139 (± 61.5), and 66.16 (± 67.37) in subjects with CPITN > 18. There was a significant interaction effect between time of TAC evaluation and patients' periodontal state (p = 0.009).

Conclusion

This study confirmed the association between periodontal status and smoking, and the association with salivary antioxidant capacity. A significant alteration in TAC of whole saliva in cases with clinical periodontal problems after green tea consumption was indicated.

Clinical significance

Considering the safety and availability of green tea, it can be used as a preventive or supplementary treatment in periodontal problems, especially in smokers, after further investigation.
