The short and long-term fluoride release of 16 products (seven conventional glass-ionomers, five light-activated glass-ionomers, two polyacid-modified resin composites and two resin composites) commercialized as fluoride-releasing materials were measured. A potential link between the material type and its level of fluoride release was researched. The fluoride release was evaluated after different time intervals. Initial fluoride release from all materials was highest during the first 24 h and decreased sharply over the first week. Some groups of materials appeared to be significantly different after, respectively, 7 and 91 days. However, it was impossible to correlate the fluoride release of the materials by their type (conventional or resin-modified glass-ionomers, polyacid-modified resin composite and resin composite) except if we compared the products from the same manufacturer. The link between fluoride release and an acid-base reaction seems to be confirmed. The glass-ionomer composition (glass particles and polyacid's type, powder/liquid ratio) should have more influence on fluoride release than material type.
对作为氟释放材料商业化的16种产品（7种传统玻璃离子体、5种光固化玻璃离子体、2种聚酸改性树脂复合材料和2种树脂复合材料）的短期和长期氟释放情况进行了测量。研究了材料类型与其氟释放水平之间的潜在联系。在不同时间间隔后对氟释放情况进行了评估。所有材料的初始氟释放在最初24小时内最高，并在第一周内急剧下降。分别在7天和91天后，某些材料组似乎存在显著差异。然而，除了比较同一制造商的产品外，不可能根据材料类型（传统或树脂改性玻璃离子体、聚酸改性树脂复合材料和树脂复合材料）来关联材料的氟释放情况。氟释放与酸碱反应之间的联系似乎得到了证实。玻璃离子体组成（玻璃颗粒和聚酸类型、粉液比）对氟释放的影响似乎比材料类型更大。
