Introduction & Aim
Tea consumption had beneficial effect on dental caries. The aim of the present study was to evaluate the effect of green tea and black tea on salivary PH.
Methods
In this Clinical Trial and analytical study (2014) salivary sample of 50 healthy male Zahedan dentistry students 20-22 years old were collected for evaluation salivary PH. From all volunteers was asked to consume black tea on the first day and after collecting saliva samples (in the manner described below), it was replaced with Green tea and after that, in the second day before and after consuming Green tea samples was collected again. For sampling, on the first day (8-9 A.M) was asked from each volunteer, before consuming Black tea, trickle their unstimulated saliva into the test tubes through his lower lip within 3 minutes and every 60 seconds (in seated position) and after half an hour recollect the samples 1, 5 and 10 minutes after ingestion of 250 ml Black tea without any sweetener in separate tubes (For each volunteer, test tubes was numbered 1 to 4) and it was transferred to laboratory to evaluate salivary PH. Then was asked volunteers to replace Black tea with Green tea on that day. On the second day (8-9 A.M) was asked each volunteer, before consuming Green tea, trickle their unstimulated saliva into the test tubes through his lower lip within 3 minutes and every 60 seconds (in seated position) and after half an hour recollect the samples 1, 5 and 10 minutes after ingestion of 250 ml Green tea without any sweetener in separate tubes (For each volunteer, test tubes was numbered 1 to 4) and it was transferred to laboratory to evaluate salivary PH. In the laboratory amount of salivary PH was measured by digital PH-meter. Data analyzed by SPSS v21, T-test.
Results
Mean salivary PH before green tea consumption (7.15±0.05) and after green tea consumption (7.56±0.09) had significant difference (p
