Abstract　： [Abstract] It has been proven that fluoride applications are effective for prevention of coronal and root caries in adults and the aged. The authors previously reported that the denture base resin that was often used for adults and the aged had the possibility of a continuous delivery of a micro dose of fluoride into the oral cavity. The objective of this study was to compare the capacities of charge and the release of fluoride in various resin materials used in daily clinical care, and the possibility of these materials being used as a fluoride delivery vehicle was studied. This study found the following. 1. It was observed that cast resin, heat-curing resin and polysulfone resin charged and released fluoride. 2. The release of charged fluoride into artificial saliva was observed to continue for thirty minutes in heat-cured resin and polysulfone resin and for two hours in cast resin. 3. The capacity of the slow release of fluoride into artificial saliva was the highest in cast resin. 4. The total amount of fluoride released from denture base resins into artificial saliva in cast resin was significantly higher than in other denture base resins. These results suggested that denture base resin had the possibility of being a fluoride delivery vehicle. Cast resin had an acceptable characteristic of slowly releasing fluoride. The amount of fluoride released from cast resin was sufficient to contribute to the prevention of dental caries. Therefore, it was suggested that cast resin could be a new vehicle for topical fluoride application.
