Settings and conduct
-
The study is conducted on dental students in Zahedan. Prophylaxis takes place on the first day. Sampling is done at 10-12 in the morning.Saliva sampling for different fruits is done at different times (in the same group). The minimum time interval between consuming two fruits is 1 day. First, a baseline saliva sample is prepared (the study group is considered as a control on the first day), then the consumption of fruits starts in the following days. On the second day, the unstimulated saliva is collected in a sitting position before consuming the fruit within 3 minutes and every 60 seconds using the spitting method, and half an hour later re-sampling 1, 5 and 10 minutes after consuming a 200 gram fruit in Separate tubes are made (the test tubes are numbered from 1-4 for each person) and they are transferred to the lab to evaluate the pH of saliva. Then, in the following days, sampling is done for other fruits in the same way.
