Abstract
Dental caries is still prevalent despite the current understanding and use of fluoride. Faster dissolving crystals of NaF in a dentifrice could improve the efficacy of current preventative treatments. In this study, crystals of sodium fluoride with a high surface area to volume ratio were prepared by the addition of an aqueous solution of sodium fluoride to an antisolvent method using ethanol. Key variables in the preparation of these crystals included the amount of water present in the antisolvent, the ratio of salt solution to antisolvent and the rate of stirring. The dissolution of these high surface area to volume crystals were measured using a conductivity probe. The dissolution rate of these crystals were greater compared to commercial grade sodium fluoride with cubic crystal morphologies.
