Abstract

Purpose: This study aimed to evaluate the fluoride release of conventional glass ionomer (GI) modified with flax fibers and/or ethanolic extract of propolis (EEP) with and without thermo-cycling. Materials and Methods: 80 total discs of GI were prepared, 20 discs per group: Group (GI) conventional glass ionomer (control), Group (F) glass ionomer incorporated with 5% flax fibers, Group (P) glass ionomer incorporated with 1% ethanolic extract of propolis (EEP), Group (FP) glass ionomer incorporated with 5% flax fibers and 1% ethanolic extract of propolis (EEP). Fluoride release testing was performed after the first day and after 7 days. Results: Conventional Fuji IX Gold Label (GI) revealed the lowest fluoride release mean values, Propolis modified Fuji IX Gold Label (P) showed higher mean values followed by Flax fibers and Propolis modified Fuji IX Gold Label (FP), while Flax fibers modified Fuji IX Gold Label (F) revealed the highest mean fluoride release value. Conclusion: Incorporation of 5% Flax fibers enhanced the initial fluoride release of conventional glass ionomer.
