Abstract

In this study, total fluoride (TF) in commercial toothpastes for children in Korea was evaluated and compared with the fluoride concentration declared by the manufacturer (Declared F). Additionally, total soluble fluoride (TSF) was evaluated and compared with TF. Ten toothpastes were coded with letters to allow blind analysis. For evaluation of TF, each toothpaste was homogenized in deionized water. For evaluation of TSF, each toothpaste was centrifuged and then, the supernatant of the sample was evaluated. Fluoride concentrations were assessed using a fluoride electrode coupled to an ion analyzer. Only one toothpaste showed lower TF concentration than Declared F. In all toothpastes, TSF was similar to the TF.
