title: Salivary and urinary fluoride levels after 1-month use of fluoride-releasing removable appliances.
abstract: Forty children aged 8-10 years participated in this study. Half (n =20) of them used orthodontic appliances which contained fluoride-releasing devices embedded in the lingual surface of the appliance and the other half used orthodontic appliances prepared from a fluoride-releasing acrylic polymer. Prior to the adjustment of appliances and after 1, 7, 14, 21 and 30 days salivary and urinary samples were collected and the fluoride concentrations were determined. The mean fluoride release was highest during the first week. However, the values decreased considerably after that and the curves for the two groups became parallel. The results indicate that fluoride-releasing removable appliances could be useful for a prolonged release of low concentrations of fluoride without any systemic effect.
