Fluoride Release From GIC And Titanium :Interference Assessment By Characterisation

Objectives:This study aimed to investigate the effect of alpha crystalline particles of titanium when incorporated into glass ionomer cement on its fluoride release characteristics. Methods: GIC samples were divided into two groups. In the first group the matrix was replaced with alpha crystalline particles of titanium metal.The second group served as the control group with no changes in the glass ionomer cement.The two groups were subjected to acid washing and than kept in different Ph mediums of 3, 7 and 10. The samples were also incubated to see the effect of temperature. Samples were further investigated using SEM quantitative analysis and X ray Diffraction . Flouride was measured using ion potentiometer. Results: Release of Flouride from group 1 was found to be significantly lesser than that of group 2 which did not have titanium inclusions.XRD and SEM analysis showed that the total Flouride release was partially prevented by titanium particles. During the period of experiment, 28 days, the total Flouride release seemed to depend on the square root of time. Conclusions:The incorporation of titanium particles within the laboratory produced glass ionomer lessened the release of Flouride which can be attributed to the development of titanium complexes within the poly salt matrix of glass ionomer cement.
