摘要
目的:龋齿仍然是儿科牙科的一个普遍问题,需要修复材料,不仅修复龋齿,而且提供保护的好处。释放氟化物的修复材料通过抑制细菌活性和促进再矿化在预防龋齿复发方面具有关键作用。本研究的目的是研究三种儿童牙科修复材料riva Light Cure HV、Fuji IX GP Fast和Cention Forte充填材料在不同pH和温度条件下的氟释放情况。方法:标本直径10 mm,厚度2 mm;每种材料N = 3)根据制造商的说明制备;浸泡在pH为4.8、6.8和8.8的缓冲液中;分别保存在37℃和44℃。采用离子色谱法在3个时间点(1天、7天和28天)定量氟化物释放。结果:pH、温度、时间对氟释放量有显著影响(p < 0.05)。Riva Light Cure HV表现出最高的释放量,特别是在酸性条件下(pH 4.8),在44°C条件下,28天后达到40.14 mg/L。富士IX GP Fast的释放量随着时间的推移而增加,但累积浓度较低。较高的温度通常会增强氟化物在所有材料中的扩散。结论:这些发现强调了环境因素对氟释放动力学的关键影响。Riva Light Cure HV显示出优越的氟化物释放,特别是在酸性环境中,这表明它对高龋风险的儿科患者有潜力。这些见解可以为儿童牙科修复材料的选择提供信息,优化龋齿预防策略。
Fluoride Release from Pediatric Dental Restorative Materials: A Laboratory Investigation.
Objectives: 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-Riva Light Cure HV, Fuji IX GP Fast, and the Cention Forte Filling Material-under different pH and temperature conditions. Methods: 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). Results: The data revealed that fluoride release was significantly influenced by pH, temperature, and time (p < 0.05). Riva Light Cure HV exhibited the highest release, particularly in acidic conditions (pH 4.8), reaching 40.14 mg/L at 44 °C after 28 days. The Cention Forte Filling Material and Fuji IX GP Fast also showed increased release over time, but with lower cumulative concentrations. Higher temperatures generally enhanced fluoride diffusion across all materials. Conclusions: These findings emphasize the pivotal impact of environmental factors in fluoride release dynamics. Riva Light Cure HV 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.
