ClinConnect Summary

This clinical trial is studying how well matcha green tea can help balance saliva pH after it has been exposed to acidity, which can happen from eating certain foods or drinks. The researchers want to see if drinking hot or cold matcha tea can help restore the pH level in saliva as effectively as plain water. Participants will include healthy adults between the ages of 76 and 91 who have good dental health and practice regular oral hygiene.

If you decide to participate, you'll first undergo a health check and provide consent. Then, saliva samples will be taken at different times before and after an acidic challenge. After the challenge, you will swish with either hot matcha, cold matcha, or water, and more saliva samples will be collected over the next 40 minutes. This study is not yet recruiting participants, and certain criteria must be met to join, including not having any current oral diseases or systemic health issues. Your comfort and health are priorities, so those who smoke, are pregnant, or have specific medical conditions won't be eligible.
