| description | <b>Objectives:</b> Dental caries remains a prevalent issue in pediatric dentistry, necessitating restorative materials that not only repair decay but also provide protective benefits. Fluoride-releasing restorative materials have a key function in preventing recurrent caries by inhibiting bacterial activity and promoting remineralization. The objective of this study was to examine fluoride release from three pediatric dental restorative materials—<i>Riva Light Cure HV</i>, <i>Fuji IX GP Fast</i>, and the <i>Cention Forte Filling Material</i>—under different pH and temperature conditions. <b>Methods</b>: Specimens (10 mm diameter and 2 mm thickness; n = 3 for each material) were prepared according to the manufacturers’ instructions; immersed in buffer solutions at pH 4.8, 6.8, and 8.8; and stored at 37 °C and 44 °C. Fluoride release was quantified using ion chromatography at three time points (1 day, 7 days, and 28 days). <b>Results</b>: The data revealed that fluoride release was significantly influenced by pH, temperature, and time (<i>p</i> < 0.05). <i>Riva Light Cure HV</i> exhibited the highest release, particularly in acidic conditions (pH 4.8), reaching 40.14 mg/L at 44 °C after 28 days. The <i>Cention Forte Filling Material</i> and <i>Fuji IX GP Fast</i> also showed increased release over time, but with lower cumulative concentrations. Higher temperatures generally enhanced fluoride diffusion across all materials. <b>Conclusions</b>: These findings emphasize the pivotal impact of environmental factors in fluoride release dynamics. <i>Riva Light Cure HV</i> demonstrated superior fluoride release, particularly in acidic environments, suggesting its potential for high-caries-risk pediatric patients. These insights can inform the selection of restorative materials in pediatric dentistry, optimizing caries prevention strategies. |
