| Outline of Final Research Achievements |
To enhance anti-caries effect of glass-ionomer based orthodontic adhesives, silico fluoride solution was evaluated to adhesive as a souse of fluoride. In case of lower pH, glass ionomer particles was dissolved by fluoride solution. However, when pH was adjusted to neutral range, fluoride uptake and release was observed through glass ionomer layer, then decalcification of teeth was inhibited. On the other hand, with respect to the residual amount of fluorine contained in the adhesive material for a long term evaluation, it was revealed that the fluorine was eluted from adhesive materials although the pH was adjusted neutral area.
