Abstract:
The objective of this study was to compare the setting kinetic, static physical/mechanical properties, and ion release of the recently developed conventional glass ionomer cement contained elastomeric micelles (Deltafil, DF) with the commercial conventional glass ionomer cement (EQUIA Forte ; EF, Fuji IX ; F9, Ketac Molar ; KM). Materials and method: The acid-base reaction of the materials was determined using FTIR-ATR (n=3). Biaxial flexural strength/modulus (n=10) and Vickers surface microhardness (n=5) were determined after immersion in water for 24 h and 4 weeks. Ion release was analyzed using fluoride-specific electrodes and ICP-OES (n=5). Results: The extrapolated degree of acid-base neutralization of all materials was comparable (~97%) (p>0.05). Additionally, DF exhibited the highest BFS, which was significantly higher than that of EF, F9, and KM. The highest fluoride release was observed with EF, followed by F9, KM, and DF. However, DF had significantly lowest 5 Vickers microhardness values compared to other materials tested. For the cumulative ion release, concentrations of Al, P, and Sr were all detected, but a higher amount of Sr was observed from DF compared to other materials tested. Conclusion: The recently developed conventional GIC with added elastomeric micelles exhibited a satisfactory setting reaction and mechanical properties but with lower fluoride release. Therefore, this material may not be suitable for patients with high caries risk, but it may be indicated for use in moderate-high loading areas where mechanical strength is a primary concern in clinical conditions.
