The aim of this study was to test the dose of fluoride toothpaste by parents for their children aged up to 24 months.
Parents who use fluoride toothpastes for their children were asked to dose two commercially available toothpastes (A and B) with 1000 ppm fluoride each for their children as they would normally do at home. The toothpaste amounts were weighed, and as reference, the weight of an 'optimal' grain of rice-size amount of each toothpaste was used.
61 parents dosed a mean of 0.263 ± 0.172 g toothpaste A and 0.281 ± 0.145 g toothpaste B. The parents' mean doses were 5.9 times higher for toothpaste A and 7.2 times higher for toothpaste B than an 'optimal' grain of rice-size amount (the reference dose as recommended). The difference between parent's and reference dose was statistically significant (p < 0.001). Moreover, 39.3% of parents were not aware about conditions of use and warnings that have to be printed on the package of fluoride toothpastes.
In this study, parents significantly overdosed the toothpaste for their children. To avoid fluoride intake from toothpaste, parents can choose fluoride-free alternatives for the oral care of their infants and toddlers.
本研究旨在测试家长给24个月及以下儿童使用含氟牙膏的剂量。
要求那些给孩子使用含氟牙膏的家长，按照他们在家中的常规做法，给孩子使用两种市售含氟牙膏（牙膏A和牙膏B），每种牙膏的氟含量均为1000 ppm。对牙膏用量进行称重，并以每支牙膏“最佳”米粒大小用量的重量作为参考。
61位家长给孩子使用的牙膏A平均剂量为0.263±0.172克，牙膏B平均剂量为0.281±0.145克。家长们使用的牙膏A平均剂量比“最佳”米粒大小用量（推荐的参考剂量）高5.9倍，牙膏B高7.2倍。家长使用剂量与参考剂量之间的差异具有统计学意义（p<0.001）。此外，39.3%的家长不知道含氟牙膏包装上必须印有的使用条件和警告。
在本研究中，家长给孩子使用的牙膏剂量明显过量。为避免孩子从牙膏中摄入氟，家长可为婴幼儿选择不含氟的口腔护理产品。
