The purpose of this in vitro study was to appraise the resin-based sealants for colour stability and fluoride release, as indicators for material structure alteration. For colour stability, Fotoseal® and Fissurit FX® samples were immersed in: orange juice, non-carbonated drink, carbonated drink and distilled water, and we estimated the variation of the CIE lab parameters. The concentration of fluorine anions was determined by potentiometric method. Fotoseal® express the largest variations of colour parameters, in carbonated drink and orange juice and release less fluoride. In conclusion, colour changes reveal structural outcomes in material resin matrix..
