Efficacy of Matcha Tea on Patients With Biofilm-induced Gingivitis

Gingivitis is the most common form of periodontal disease (PD). In a survey conducted in three Latin American cities, gingivitis was detected in approximately 99.6% of 1650 subjects. It is defined as inflammation affecting gingival tissue surrounding teeth. Clinically, it is characterized by gingival redness and edema with no periodontal attachment loss.

The generation of reactive oxygen species (ROS) and other free radicals (R) during metabolism is a normal process that ideally is compensated by an endogenous antioxidant system. However, due to many environmental, lifestyle, and pathological situations, excess radicals can accumulate, resulting in oxidative stress. Oxidative stress (OS) has been related to cardiovascular disease, cancer, and other chronic diseases. It also plays an important role in the pathogenesis of periodontal disease.

Inflammatory response is a part of many diseases. It may lead to the production of excessive amounts of substances promoting the production of reactive oxygen species (ROS), which can damage cell structures and lead to long-term disruption in the functioning of the body.

One solution to keeping the appropriate oxidative balance is a high supply of exogenic antioxidants that aims to equalize and prevent oxidative processes. It is also important to maintain a correct lifestyle, free from stress-inducing factors.

There are 3 main varieties of tea: green, black, and oolong. The difference is in how the teas are processed. Green tea is made from unfermented leaves and reportedly contains the highest concentration of powerful antioxidants called polyphenols.
