Outline of Final Research Achievements |
This study aimed to create a thick hydroxyapatite (HA) film on the surface of a human tooth via a powder jet deposition (PJD) device for dental handpieces, and to examine the microstructural and mechanical properties of the FHA film. The FHA particles in the deposited film were densely packed, and the three-dimensional microstructure and the rough surface of the FHA film were unchanged after thermal cycling. There were also no significant differences in the hardness and the bonding strength between the FHA film before and after thermal cycling.

Academic Significance and Societal Importance of the Research Achievements |
本研究成果をもとに高齢者根面う蝕の長期的予防、再治療のないう蝕治療法が確立されれば、さらなる歯の残存率増加につながり、機能的・審美的に優れた口腔内環境を保つことでQOLの向上に寄与できるものと考えられる。患者の身体的・心理的・経済的負担は小さくなり、多くの患者にとって利益向上につながる手法である。さらに、今後ますます増加が予想される高齢者根面う蝕の発生を抑えることで、う蝕治療やそれに引き続く口腔外科治療、補綴治療を減少させ、歯科医療費の抑制に貢献できることが期待される。
