Fluoride release and flexural strength of four ion-releasing restorative materials: An in vitro comparative study.

Background: This study aimed to determine the fluoride release and flexural strength of four ion-releasing restorative materials.

Material And Methods: A total of 80 samples of four different materials were prepared in standardized molds: Ketac Universal, Beautifil II, Cention N, and Equia Forte Fil. The fluoride release was quantified at 1, 3, 7, 14, and 28 days post-immersion using an ion-selective electrode.
