The use of Fluoride in topical gel and foam containing Fluoride have become two of the commonly available dental treatments that are used to reverse demineralization and reverse tooth decaying process.  Previous research showed FIA to be a fast measurement method for low level fluoride samples. This new study demonstrates the ease of application for these samples, which are simply treated to give an aqueous solution and then mixed with TISAB II and injected into a Flow Injection Analysis system employing an Ion-Selective Electrode as the ion detector. The precision of the gel and foam delivery systems were evaluated. The values found in both the dental products are reported and compared to label claims.
