Brief summary

Aim of the study: This study aims to evaluate the antioxidant and beneficial effects of matcha tea daily intake on periodontal health. Objectives: * To evaluate the salivary level of antioxidants (catalase, total antioxidant capacity) after matcha tea intake compared to green tea over a period of one month. * To evaluate the clinical periodontal parameters including bleeding on probing (BOP), probing pocket depth (PPD) and plaque index (PI) after matcha tea intake compared to green tea over a period of one month. * To evaluate the salivary levels of IL-1B after matcha tea intake compared to green tea over a period of one month.

Design outcomes

Primary

MeasureTime frameDescription
change in salivary level of antioxidant marker30 Days (baseline to one moth of tea intake)change in level of catalase enzyme in ku/L
change in salivary level of ant-inflammatory marker30 Days (baseline to one moth of tea intake)change in level of interleukin- one beta (IL-1B) in pg/L

Secondary

MeasureTime frameDescription
change in percentage of bleeding on probing (BOP)30 Days (baseline to one moth of tea intake)change in BOP percentage. less percentage means less inflammation in gingival tissue
change in plaque index (PI) scores30 Days (baseline to one moth of tea intake)change in PI scores. less scores mean less dental plaque accumulated onto teeth surfaces
