Despite recommendations that pre-school children use toothpaste containing 500-550 ppm of fluoride, there has been an increase in non-fluoridated toothpastes marketed for children. This study investigated children's toothpaste in Australia.
A comprehensive audit of all toothpastes marketed for pre-school children and available in store in the Macarthur region of NSW, Australia, was carried out. All toothpastes available for purchase were obtained and examined; size and price were catalogued, along with ingredient lists and fluoride levels.
One hundred and seven individual toothpastes were identified in the audit, with 67 (62.6%) containing no fluoride. Of the 40 fluoridated toothpastes, only 11 (10.3%) contained the recommended level of fluoride of 500-550 ppm. Twenty-two (20.6%) of all toothpastes were made in Australia, all of which were non-fluoridated. Six (5.6%) of the toothpastes studied contained excessive levels of fluoride (1350-1500 ppm). Seventeen of the 20 least expensive toothpastes contained fluoride, while 18 of the 20 most expensive toothpastes were non-fluoridated.
Despite expert recommendations, the majority of children's toothpaste available in Australia contains either no fluoride or the wrong levels of fluoride. Further study is needed to determine why this change is occurring and what is influencing the increase in non-fluoride toothpastes on the market.
尽管有建议称学龄前儿童应使用含氟量为 500-550ppm 的牙膏,但市场上针对儿童销售的无氟牙膏却有所增加。本研究调查了澳大利亚的儿童牙膏。
对新南威尔士州麦考瑞地区商店中销售的所有针对学龄前儿童的牙膏进行了全面审计。购买了所有可购买的牙膏,并对其进行了检查;记录了牙膏的大小和价格,以及成分列表和氟化物含量。
在审计中发现了 107 种不同的儿童牙膏,其中 67 种(62.6%)不含氟。在 40 种含氟牙膏中,只有 11 种(10.3%)含有推荐的氟化物水平 500-550ppm。所有含氟牙膏均由澳大利亚制造,且均为无氟牙膏。所研究的牙膏中有 6 种(5.6%)含有过量的氟化物(1350-1500ppm)。在 20 种最便宜的牙膏中有 17 种含有氟化物,而在 20 种最贵的牙膏中有 18 种为无氟牙膏。
尽管有专家建议,但澳大利亚市场上大多数儿童牙膏要么不含氟,要么氟化物含量不正确。需要进一步研究以确定为什么会发生这种变化,以及是什么因素导致市场上无氟牙膏的增加。
