Buffering Capacity of Matcha Green Tea on Salivary PH After an Acidic Attack
63 participantsStarted 2024-09-01
Plain-language summary
This study is conducted to evaluate the buffering capacity of hot matcha brew in comparison with cold matcha brew and water on salivary pH after an acidic attack using a digital pH meter.
Research Question:
Will matcha green tea beverage have similar salivary buffering effect as water after an acidic challenge on dental interns? Steps in short
1. Recruitment of the patients and clinical examination with medical and dental history taking.
2. Informed consent taking for the eligible participants to participate in the study.
3. A volume of 2 mL saliva samples will be collected before the commencement of acidic attack, baseline (T0).
4. After the acidic attack, saliva will be collected again by spitting method and their pH value will be measured (T1).
5. After 5 minutes of the acidic attack, participants will be instructed to swish either hot matcha tea, cold matcha tea, or water then swallow, and saliva samples will be collected (T2).
6. Then saliva will be collected after 10 (T3), 20 (T4), 30 (T5), and 40 (T6) minutes.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
