Measurement of Fluoride Ion Release From Restorative Material Using an Ion-Selective Electrode and Ultraviolet–Visible Light Spectrophotometer

Conventional glass ionomer cement (GIC) showed the highest fluoride release followed by enhanced resin-modified GIC and giomer irrespective of the methods used. Fluoride ion concentration values obtained from the ISE method, and spectrophotometer method were comparable. Alizarin red dye can be used as an alternative to sulfanilic acid azochromotrop dye for the estimation of the release of fluoride ions from dental materials, which is known to be sensitive and much more economical compared with the latter.
