“…Our study also shows that F1s peaks originate both from organic fluoride (689.0 eV) and metallic fluoride (686.0 eV), suggesting that fluoride will react with Al or Sr in the glass core. Furthermore, Jones 26) reported that fluoride ion uptake of GIC based on calcium alminosilicate glass correlated with the formation of a surface layer rich in Ca and fluoride, and possibly containing CaF2. In our study, XPS detected Ca from added HAp in the matrix of four HAps-added GICs.…”

“…Samples were prepared by syringe-loading the mixed cement (P/L=3.6) into 6 mm diameter×2 mm high stainless steel split molds, pressing with cellulose acetate sheets and a glass plate, and clamping for 1 hour to obtain matrix-rich surfaces according to Jones' methods 26) . For XPS, the X-ray source was MgK, at 400 W and 14 kV.…”

Hydroxyapatite particle characteristics influence the enhancement of the mechanical and chemical properties of conventional restorative glassionomer cement

The aims of this study were to improve the mechanical and chemical properties of conventional restorative glass ionomer cement (GIC) by adding hydroxyapatite (HAp) preparations with different characteristics, and to investigate the underlying reaction mechanisms. Fuji IX GP ® was used as the control GIC. The experimental GICs consisted of four HAp-particles with different characteristics added at 8 mass% to Fuji IX-powder. All cements were prepared by mixing with Fuji IX-liquid (P/L=3.6). Four HApparticles were analyzed, and then the mechanical strengths and the fluoride-ion-release-recharge-behaviors of five GIC groups were evaluated. The results of this study demonstrate that the addition of HAp particles with highly reactive properties such as high specific surface area can enhance the flexural strength and fluoride ion release properties of conventional restorative GIC. Our results further indicate that HAp functions as an adsorbent and an ion exchangeable agent, resulting in improved mechanical and chemical properties of GIC.

“…67 XPS indicates an association between F taken up and Ca. 68 What form this can take is not clear. CaF 2 is very insoluble and its addition to an F-free GIC produces no additional F release 34 , whereas, all the F taken up by this GIC is re-released.…”

“…33 In contrast, K + , which is taken up in similar amount to F À is not concentrated at the surface. 67,68 This difference in location may account to the slower re-release of K as contrasted to F. 45 Uptake of ions with valencies higher than one have only been reported infrequently. As referred to in section B, Ca 2+ from artificial saliva is deposited on the GIC surface in the form of CaF 2 .…”

The purpose of this study was to compare the microhardness and the fluoride content of enamel and dentin around fluoride-or non fluoride-containing restorations. Forty extracted human teeth were used and prepared cervical cavities on proximal surface. Experimental teeth were divided into five groups. Group 1 : Prime & Bond NT and Z100, Group 2 : Prime & Bond NT and F2000, Group 3 : Scotchbond MultiPurpose and Z100, Group 4 : Scothcbond Multi-purpose and F2000, Group 5 : Fuji II LC. The cavities were filled with dentin adhesives and restorative materials. After each tooth was bisected, one half was tested microhardness and the other half was analyzed the fluoride at the enamel and dentin by an EPMA-WDX device. The results were as follows:1. There was no statistical difference among the microhardness of enamel surface in all group. 2. The microhardness at dentin of 100 ㎛ point in Group 2 and 20 ㎛ point in Group 4 was lower than that of normal dentin (p>0.05). 3. There was no statistical difference among the fluoride content of enamel surface in all group. 4. The fluoride content at the dentin of 30 ㎛ point in Group 2 and 5 were higher than those at 100 ㎛ and 200 ㎛ point in Group 2 and normal dentin (p<0.05). 5. At the dentin of 30 ㎛ point, Group 2 showed higher fluoride content than Group 1 and 3, and Group 5 showed higher fluoride content than other groups. [J Kor Acad Cons Dent 29(1):36-43, 2004]
