title: Potential natural antioxidants: adjuvant effect of green tea polyphenols in periodontal infections.
abstract: OBJECTIVE
  Polyphenols constitute the major component in green tea, which represent a cluster known as catechins. The presence of polyphenols, especially the amino acid theanine and catechins with its antioxidant properties in green tea make them ideal for medicinal- dental applications. The objective of the paper is to delineate the role of green tea polyphenols in periodontal disease.
  
  
  METHODS
  The Pub med data base was searched for human clinical studies, reviews pertinent to application of green tea polyphenols in periodontal health dating from Sep 1980- Sep 2014.
  
  
  RESULTS
  The retrieved inference from the epidemiological surveys, in vitro studies and overviews of polyphenols, postulate green tea as potential natural antioxidant. Green tea mouthwashes possess limitations, which make them ineffective during the chronic stages of periodontitis. Human studies reveal that the prognosis of periodontal disease is better when the green tea catechins are used via local drug delivery.
  
  
  CONCLUSIONS
  The maintenance of periodontal health could be enhanced by emphasizing the habit of drinking green tea in periodontitis patients. The future scope of the research demands the analysis of polyphenols at molecular level to have a better understanding of its overwhelming applications.
