| Outline of Final Research Achievements |
A functional fluoridated hydroxyapatite (FHAp) sheet that promotes dentin fastening and provides acid resistance was developed, and the technology for rapidly and strongly fixing the FHAp sheet onto dentin was established. First, the optimal conditions for fabricating FHAp thin films using pulsed laser deposition (PLD) were determined. Next, it was shown that a resist coating silicon substrate was useful as an isolation substrate for manufacturing FHAp sheets. The FHAp sheets were found to have five-fold greater acid resistance compared with HAp sheets. Furthermore, we established a pasting method that rapidly and strongly fixed the FHAp sheet onto the dentin.
