Correlation between fluoride release, surface hardness and diametral tensile strength of restorative glass ionomer cements.

Background: The aim of this study was to determine if there is a correlation between fluoride release, surface hardness, and diametral tensile strength of restorative glass ionomer cements (GICs).

Material And Methods: Conventional (Riva Self Cure) and resin-modified (Riva Light Cure) GICs were used. Thirty-four samples (ø 6 x 3 mm) were prepared for each cement.
