Abstract:
The importance of fluoride intake for maintaining dental health is widely recognized. One simple, reliable, and cost-effective method for analyzing the fluoride content as ion (F-) in solutions is through potentiometric analysis using a fluoride ion-selective electrode. This electrode allows for the detection of even very low concentrations of fluoride ions (10-6 mol.dm-3). The purpose of this study was to estimate the fluoride contents in various commercially available tea infusions with a specific focus on risk of dental caries and fluorosis. To conduct the analysis, 100 mL samples of 44 different tea brands were kept at boiling temperature and fluoride concentrations were measured at 5, 10 and 15 minutes using ion selective electrode. In the case of tea bags, the fluoride content was analyzed after 5 minutes of steeping in boiling water without additional heating. The results showed that after 5 minutes of boiling, the average fluoride concentrations in black, green, and herbal tea infusions ranged from (1.51 - 7. 97) mg/L, (1.22 - 5.94) mg/L and (0.08 - 0.16)mg/L respectively.
