技術說明

在牙齒上塗氟化物可以防止蛀牙。但是，牙齒表面所沉積的氟化鈣硬度不高且耐磨損性差，因此，必須要經常在牙齒上塗氟化物。所以本發明使用CO2雷射光照射牙齒，以增加氟化鈣的機械性質。並且透過實驗的形貌分析、奈米硬度、彈性模數與奈米磨耗，證明氟化鈣的機械性質能有效被提升。當CO2雷射光照射塗佈在牙齒上的氟化鈣沉積物5秒後，氟化鈣狀沉積物的耐磨性提高約34%，若照射10秒能提升至40%。另外，也發現能有效的增加氟化鈣的吸收23%。整體來說，雷射治療能夠有效的提高氟摻入牙組織和氟化鈣保護層的耐磨性。 Topical fluoride treatment prevents dental caries. However, the resulting calcium-fluoride-like deposits are soft and have poor wear resistance; therefore, frequent treatment is required. The present creation have used CO2 Laster to increase the mechanical properties of the calcium-fluoride-like deposits. And, through the analysis of experiment for morphology, nanohardness, elastic modulus, nanowear identify the mechanical properties of the calcium-fluoride-like deposits can be significantly improved. The wear resistance of the calcium-fluoride-like deposits improved about 34% after laser irradiation for 5 sec and about 40% following irradiation for 10 sec. In addition, the laser treatments increased fluoride uptake by at least 23%. Overall, laser treatment significantly improved fluoride incorporation into dental tissue and the wear resistance of the protective calcium-fluoride layer.
