People in Lebanon turned to bottle water consumption because of its poor public water quality. In general, fluoride is known as dental caries preventive. A study in 1986 and two other national surveys in 1994 and 2004 showed that the concentration of fluoride in public Lebanese water was insignificant for the prevention of dental caries (less than 0.3 mg/L). The aim of the study was to measure the fluoride concentration in the highest selling and known commercial brands for bottled water in Lebanon, as well as to assess their effectiveness regarding prevention of dental caries.
Fluoride has a notable therapeutic effect but in small doses that fluoride can be found in drinking water. Analysis using an absorptiometry of 625nm and another technique using an Orion electrode of 9609 BN have shown the low content of fluoride in the Lebanese waters (less than 0.3 mg/l). Strategies have recently been evolved based on fluroide supplementation (if the results turn negative) to reduce the index of caries in LEBANON.
由于黎巴嫩公共供水水质较差，人们转而饮用瓶装水。一般来说，氟化物被认为具有预防龋齿的作用。1986年的一项研究以及1994年和2004年的另外两项全国性调查显示，黎巴嫩公共供水中的氟化物浓度对预防龋齿而言微不足道（低于0.3毫克/升）。该研究的目的是测量黎巴嫩最畅销且知名的商业瓶装水品牌中的氟化物浓度，并评估它们在预防龋齿方面的效果。
氟化物具有显著的治疗作用，但饮用水中只能发现少量的氟化物。使用625纳米吸光光度法以及使用9609 BN型奥立龙电极的另一种技术进行的分析表明，黎巴嫩水域中的氟化物含量较低（低于0.3毫克/升）。最近已制定了基于补充氟化物的策略（如果结果为阴性），以降低黎巴嫩的龋齿指数。
