    Abstract:
    OBJECTIVE: One therapeutic approach to the management of xerostomia and its related oral sequelae is the use of a supersaturated Ca2+/PO4(3-) rinse in conjunction with fluoride. This study evaluated the use of the supersaturated rinse in high-risk patients from a single dental clinic. METHODS: Patients (n = 134) at high risk for caries due to xerostomia were prescribed the calcium phosphate rinse and 1.1% NaF for daily use, and were evaluated for caries incidence over an average observation period of five years. All patients were instructed to use the rinse three to four times a day, depending on the severity of dryness of the mouth and rate of salivary flow. Compliance, or regular use of the rinse, was determined through monitoring by staff at each visit, a self-administered clinic questionnaire pertaining to usage of the rinse, and records from a single hospital pharmacy that supplied the rinse to all participating patients. Those patients who were found to typically use the remineralizing solution at least once a day during the entire follow-up period were classified as compliant. All individual surfaces at risk for caries (SAR) were examined and recorded at each visit to determine changes in average SAR per patient RESULTS: Patients who regularly used the supersaturated rinse, along with commercially available prescription sodium fluoride, were found to experience a significant increase in reversals of caries, and a significant decrease in net coronal and root surface caries increment. The mean for the compliant group was 0.034 (SD 0.303), and the non-compliant mean was 0.315 (SD 0.735) with p > 0.0001 per surfaces/month. CONCLUSION: These observations suggest that long-term compliance with the daily supersaturated rinse was protective against caries progression in a high-risk population.
