Abstract:

 Background:This study determined the fluoride contentof green tea from various parts of Asia,where green tea originates.Methods:We brewed 2.5 g each of 4 types of greentea (from China, South Korea, Japan andSri Lanka) using deionized water heated toboiling. Water was cooled to 71°C, then teawas steeped for 2 minutes.This process was repeated 20 times,thus providing 20 samples for each teatype. In addition, 20 control samples ofdeionized water were brewed to the samespecifications. Samples were analyzedusing a fluoride probe, and statistical powerwas calculated.Results:The tea samples from different countriesvaried in the amount of fluoride theycontained. The Chinese sample containedthe most fluoride, while the Japanesesample contained the least. Meansand interquartile ranges of fluorideconcentration were calculated for eachsample: Sri Lanka 3.58 ppm (0.1425),Chinese 6.83 ppm (0.140), South Korean5.36 ppm (0.0975), Japanese 1.88 ppm(0.1375) and control 0.33 ppm (0.0078).Conclusions:The origin of tea and environmentalfactors, such as pollution, groundwater, airand the soil in which it was grown appear todirectly affect the amount of fluoride thataccumulates in the plants.Considering the fluoride content revealedby this study, green tea consumptionhabits should be taken into account whenprescribing adjunct fluoride therapy as partof a preventative program for patient care.
