Objectives: To evaluate the effect of Matcha Tea versus Green Tea on the salivary pH in high caries risk patients.
Materials and methods: Total number of 24 high caries risk patients were randomized into two equal groups (n=12). Group 1 (intervention group) was given Matcha Tea and Group 2 (control group) was given Green Tea. Saliva samples were collected at baseline, immediately , after 5 minutes and after 10 minutes of administration. Salivary flow rate and pH were measured at different time intervals.
Results: For salivary flow rate; Intergroup comparison between Matcha and Green Tea have shown no statistically significant difference at baseline. While immediately, after 5 and 10 minutes, there was statistically significant difference where Green Tea showed higher increase in salivary flow rate compared to Matcha Tea. Intragroup comparison within Matcha and Green tea have shown statistically significant difference between follow-up periods where flow rate showed an increase immediately and after 5 mins periods. Then a decline in salivary flow rate occurred after a 10 mins follow up period. For salivary pH; Intergroup comparison between Matcha and Green Tea have shown no statistically significant difference at baseline, immediately, after 5 and 10 minutes. Intragroup comparison within Matcha and Green Tea have shown statistically significant difference between follow-up where salivary pH showed an increase immediately followed by a slight decline after 5 and 10 mins periods.
Conclusion: Matcha Tea is effective in increasing both salivary flow rate and salivary pH and can be used as a caries prevention means.
