The release of fluoride is an important factor in evaluating a composite restorative material due to its anticariogenic effect. Field amplified stacking injection in capillary electrophoresis was studied to determine the concentration of fluoride released from dental restorative materials. A detection limit of 20 ng/mL was obtained with good reproducibility (relative standard deviation < 4%). The method was applied to the analysis of fluoride released from four different types of commercially available dental composites over 28 days. Results showed that field‐amplified stacking injection‐capillary electrophoresis was effective in monitoring the fluoride release process and product quality of different kinds of restorative materials.
