EFFECT OF TIME ON FLUORIDE RELEASE FROM RIVA LIGHT CURE AND CENTION FORTE

Background: Dental restorative materials used for pedodontic patients play a critical role in clinical success, influenced by their water absorption and solubility characteristics in the oral environment. Aims: This study aimed to evaluate and compare the fluoride release of Riva Light Cure and Cention Forte after four different time periods. Materials and Methods: For fluoride release, ion-specific electrodes measured cumulative release at 24 hours, 1 week, 4 weeks, and 6 weeks. Forty samples were fabricated. Statistical analyses were performed using Welch’s t-test to compare the means of Riva Light Cure and Cention Forte at each time point and a post-hoc Tukey’s test. The effect size was calculated using Cohen’s d. Additionally, 95% confidence intervals were determined for the mean differences between the groups to evaluate the precision of the estimates. Results: Fluoride release analysis showed a statistically significant difference. Riva Light Cure exhibited the highest cumulative fluoride release (39.448 ± 2.077) followed by Cention forte (27.731±0.894). Cention Forte displayed an initial burst effect with high fluoride release at 24 hours. while Riva Light Cure exhibited the highest cumulative fluoride release at 6 weeks. The effect size (Cohen’s d = 7.33) confirmed a very large difference, and the 95% confidence interval (10.10–13.33) supported the reliability of the findings Conclusion: These findings aid clinicians in selecting suitable restorative materials based on fluoride dynamics, water absorption, and solubility to optimize oral health outcomes.
