Buffering Capacity of Matcha Green Tea on Salivary PH After an Acidic Attack
Sponsor: NewGiza University
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.

Hot Matcha brew
* Hot matcha brew will be prepared in usucha (thin consistency) version-2 grams of matcha powder (Dr.Baby) mixed with 30 mL of hot water (75 ̊C). The first step will be to massage the matcha powder with a small amount of water until a smooth paste forms, then additional 50 mL of hot water will be added to dilute down the concentration. The matcha will then be vigorously shaken in a lidded jar. * After 5 minutes of the acidic attack, participants will be instructed to swish 25 mL of matcha tea 34 times then swallow, and saliva samples will be collected (T2). * Then saliva will be collected after 10 (T3), 20 (T4), 30 (T5), and 40 (T6) minutes.
Water
Water (elano) at 13 ̊C swished 34 times then swallowed.
Cold matcha brew
25 mL of cold matcha brew prepared in usucha (thin consistency) version-2 grams of matcha powder (Dr.Baby) mixed with 80 mL of cold water (13 ̊C) swished 34 times then swallowed.
