IRCT20231230060572N1 IRCT 2024-05-14 Birjand University of Medical Sciences Investigating the effect of drinking green tea on the total antioxidant capacity (TAC) of saliva in young smokers and non smokers Investigating the effect of drinking green tea on the total antioxidant capacity (TAC) of saliva in young smokers and non smokers 2024-04-08 anticipated 40 Complete https://irct.ir/trial/74934 interventional Randomization: Not randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Other, Purpose: Prevention, Blinding description: The intervention is designed in such a way that the people under study or the participants and the people who are responsible for evaluating and analyzing the data do not know about the allocation of the intervention groups and are kept blind. N/A Total antioxidant capacity of saliva. Intervention 1: The first Intervention group: 20 healthy smoking volunteers were asked to consume a total of two cups of green tea per day for three weeks. Each cup is prepared by brewing 2 grams of green tea (one green tea bag) in 150 ml of hot water (80 degrees Celsius) for 3 minutes. Then, unstimulated saliva samples are collected once at the beginning of the study and once at the end of the intervention, and the TAC value of the samples is measured in the laboratory with the FRAP test. Intervention 2: The second intervention group: 20 healthy non-smoking volunteers were asked to consume a total of two cups of green tea per day for three weeks. Each cup is prepared by brewing 2 grams of green tea (one green tea bag) in 150 ml of hot water (80 degrees Celsius) for 3 minutes. Then, unstimulated saliva samples are collected once at the beginning of the study and once at the end of the intervention, and the TAC value of the samples is measured in the laboratory with the FRAP test. Undecided - It is not yet known if there will be a plan to make this available Justification or reason for indecision in sharing IPD is There is no further information.

Total antioxidant capacity of saliva. Timepoint: Measuring the total antioxidant capacity of saliva at the beginning of the study (before the start of the intervention) and three weeks after drinking green tea. Method of measurement: Determination of the total antioxidant capacity of saliva in the laboratory by spectrophotometer in terms of micromol/liter.
