| Outline of Final Research Achievements |
The evaluation method of caries due to the change of calcium using In-air micro-PIXE / PIGE measurement method developed by us correlated with the decalcification evaluation by micro CT. Although the effect of dental caries control by fluorine contained in the tooth is obvious, it was found that fluorine can be further suppressed for caries by coexisting with calcium.
Clinical evaluation by laser diagnostic equipment, objective color diagnostic method, quantitative photoexcited fluorescence method, etc. has been great influenced of individual difference and environment, and further data accumulation was necessary to summarize relevance. We were able to take the first step in the development of new materials for root caries prevention.
