Forty gingivitis adult patients were randomly assigned to drink either matcha or green tea cup twice daily for a duration of 1\u2009month. They were asked to keep their habitual oral hygiene measures. Plaque index (PI) and bleeding on probing (BOP) were recorded. In addition, saliva was collected at baseline and 1\u2009month after tea consumption. Salivary levels of CAT, TAC and IL\u20101\u03b2 were determined by ELISA. Each participant was asked to fill OHIP\u201014 questionnaire before and after tea consumption.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Following tea intake, 40.6% of the study sample had healthy gingiva. Both groups similarly showed reductions in PI (0.32\u2009\u00b1\u20090.11\u20130.22\u2009\u00b1\u20090.08) and BOP (0.24\u2009\u00b1\u20090.08\u20130.13\u2009\u00b1\u20090.07) scores after tea consumption. There was a significant difference between mean TAC before and after matcha tea consumption only. Non\u2010significant reductions in salivary levels of CAT and IL\u20101\u03b2 were detected after tea consumption. OHRQOL of participants was improved after tea, both types, consumption.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n
