Abstract

PURPOSE

This study investigated whether the report of mothers about the amount of dentifrice applied on a toothbrush could be a reliable method to estimate the inadvertent use of dentifrices.

METHODS

A cross-sectional study was conducted in a randomly selected sample of 334 mothers of children enrolled in public day care centres of a city in the Brazilian northeast. Initially, the mothers chose the figure corresponding to the amount of dentifrice used during their children's daily toothbrushing. Then, they simulated real-life conditions with the toothbrush routinely used to brush the children's teeth. The amount of dentifrice on toothbrush was weighted using an analytical scale. Data were analysed by the Kruskal-Wallis followed by the Dunn test (α = 0.05).

RESULTS

The weight of dentifrice on the toothbrush was high (> 0.3 g), mainly considering the categories 'covered only' and 'completely covered' that showed no statistical difference (p > 0.05). The proportion of agreement between the mothers' reports and the weight of dentifrice on the toothbrush was 0.23 (CI 0.18-0.28).

CONCLUSION

The mothers' report regarding the amount of dentifrice on the toothbrush by demonstrative figures was not a reliable method to estimate the inadvertent ingestion of fluoride from dentifrices.

摘要

目的

本研究调查了母亲关于牙刷上牙膏用量的报告是否可作为估计牙膏意外使用量的可靠方法。

方法

对巴西东北部一个城市公立日托中心登记的儿童的334名母亲进行了随机抽样横断面研究。最初，母亲们选择与孩子日常刷牙时使用的牙膏量相对应的数字。然后，她们用日常给孩子刷牙的牙刷模拟实际情况。用分析天平称取牙刷上的牙膏量。数据采用Kruskal-Wallis检验，随后进行Dunn检验（α = 0.05）。
