Brief Summary

Objectives: To evaluate the effect of green tea versus matcha tea on the salivary pH in high caries risk patients. Materials and methods: Total number of high caries risk patients were randomized into two equal groups (n=). Group 1 (intervention group) was given Matcha Tea and Group 2 (control group) was given green tea. A portable digital pH meter was used to measure the salivary pH at baseline and after consumption tea immediately, after 5 mins and after 10 mins.

Conditions

Salivary pH

Outcome Measures

Primary Outcomes (1)

• salivary pH

  pH of saliva to be measured

  baseline before administration of tea, immediately after administration of tea, 5 minutes after administration of tea and 10 minutes after administration of tea

Study Arms (2)
