Objetivo: avaliar a liberação de flúor de alginatos da linha Jeltrate®. Materiais e Métodos: foram avaliadas quatro marcas de alginatos divididos em quatro grupos: Jeltrate®, Jeltrate Plus®, Jeltrate Chromatic® e Jeltrate® Chromatic Ortho®. Os alginatos foram manipulados seguindo as orientações dos fabricantes. Após isso seguiu-se a confecção dos corpos de prova utilizando moldes de silicone nas dimensões de 4 mm de diâmetro e 4mm de altura. Após geleificação, os corpos de prova foram removidos dos moldes e inseridos em recipiente com 10 ml de água milliQ, por 2 min. A liberação de flúor foi medida, através de eletrodo íon seletivo conectado a um analisador de íons. Resultados: o Jeltrate Plus® foi o alginato que mais liberou flúor (247,85 µg/cm2) seguido do Jeltrate Chromatic Ortho® (217,83 µg/cm2). Jeltrate Chromatic® ( 138,21 µg/cm2) e Jeltrate® (79,61 µg/cm2). Conclusões: o Jeltrate Plus® foi o alginato que mais liberou flúor seguido do Jeltrate Chromatic Ortho®, Jeltrate Chromatic® e Jeltrate®.
