Evaluation and Comparison of Fracture Strength and Fluoride Releasing Properties of New Alkasite Materials with Conventional Restorative Material, Bulk Fill Composite and Glass Ionomer Cement: An Study.

AIM

This study aimed to evaluate and compare fluoride ion release by Cention-N (self-cure and light-cure) and conventional glass-ionomer cement (GIC) at different pH levels and time intervals.

METHODOLOGY

For fluoride release assessment, 240 samples (10 mm diameter, 2 mm height) of Cention-N and conventional glass-ionomer cement were created using rubber rings. Samples were stored in deionized water, and the cumulative fluoride ion release and change in pH were assessed using a spectrophotometer and pH meter, respectively, at the end of 7 days, 14 days, and 21 days. The obtained data were subjected to statistical analysis.

RESULTS

All three samples exhibited very high fluoride release in an acidic medium compared to the neutral medium. Although GIC demonstrated superior fluoride release, Cention-N displayed adequate fluoride release over a longer duration.

CONCLUSIONS

Within the limitations of this study, it can be concluded that both Glass ionomer cement and Cention-N showed an initial fluoride burst.
