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.
Detailed Description:
Study Settings:
The study will be carried out at the Conservative Dentistry Department, Faculty of Dentistry, Cairo University in Egypt. Ethical approval will be taken from the Research Ethics Committee of the faculty of Dentistry, Cairo University. Signed informed consent will be signed each participant.
Recruitment:
Participants will be recruited from the patients' flow at the clinics of the Conservative Dentistry Department of Faculty of Dentistry, Cairo university.
Materials:
The Commercially available green tea and matcha tea for this study will be Lipton Tea. For preparation of green tea, 2 gr of green tea will be poured into 150 mL boiling water (100°C), after 3 minutes, it will be ready for drinking. As well as for matcha tea, 3 gr of green tea will be poured into 150 mL hot water (70°C), after 3 minutes, it will be ready drinking(7) .
Methods:
On the study day, all subjects will be instructed to brush their teeth 45 minutes after eating breakfast. Between 9-11 a.m., saliva samples will be collected through spitting method, one hour after breakfast and 15 minutes after brushing(7)
. For making the subjects blind to which tea they are drinking, the prepared tea will be served in the dark glasses. After drinking the green tea and matcha tea, every subject will be asked to bend his head forward and spit his saliva into laboratory tube every 60 seconds for 2-5 minutes. Samples will be collected immediately and 5 minutes after drinking tea(7)
.
.
Aim of the study:
The aim of this study is to evaluate the effect of green tea versus matcha tea on the salivary pH in high caries risk patients.
Research question:
In high caries risk patients, will matcha tea have the same effect as green tea on salivary pH?
