Results of the studies indicate that fluoride content in beverages may be highly variable and children can consume substantial amounts of fluoride with these products. Ingestion of excessive fluoride during infancy and early childhood may cause dental fluorosis of permanent maxillary central incisors--the most aesthetically important teeth. The aim of this study was to determine the fluoride content in Polish beverages designed for infants and young children nutrition. Forty-three brands of juices and juice-flavored drinks and 23 instant teas were evaluated. Analyses were performed with the use of ion-selective fluoride electrode (09-37 type) and a RAE 111 chloride-silver reference electrode (MARAT). Fluoride concentrations in most beverages did not exceed 0.3 ppm. However, in three beverages containing tea extract levels of fluoride were higher (0.35-1.14 ppm). Consumption of these beverages could significantly increase child's fluoride exposure. Therefore, the need exists for continuous monitoring of fluoride levels in products intended for children. Listing fluoride content on beverages would be desirable. Knowledge about possible fluoride ingestion from dietary sources permits the clinician to recommend the safest schedule of fluoride treatment so as the optimal caries preventive effect can be obtained and the risk of dental fluorosis reduced.
研究结果表明，饮料中的氟化物含量可能差异很大，儿童可能会通过这些产品摄入大量的氟化物。婴儿期和幼儿期摄入过多的氟化物可能会导致上颌恒中切牙的氟斑牙——这是最重要的美学牙齿。本研究旨在确定为婴儿和幼儿营养设计的波兰饮料中的氟化物含量。评估了 43 种果汁和果汁味饮料以及 23 种速溶茶。使用离子选择性氟电极（09-37 型）和 RAE 111 氯化银参考电极（MARAT）进行了分析。大多数饮料中的氟化物浓度不超过 0.3ppm。然而，在三种含有茶提取物的饮料中，氟化物含量较高（0.35-1.14ppm）。饮用这些饮料可能会显著增加儿童的氟暴露。因此，需要对儿童用产品中的氟化物含量进行持续监测。在饮料上列出氟化物含量是可取的。了解饮食来源中可能摄入的氟化物，可以让临床医生推荐最安全的氟化物治疗方案，从而获得最佳的防龋效果，并降低氟斑牙的风险。
