研究了15种商用释氟修复材料的抗压强度、释氟量和回灌量分布。这些材料包括玻璃离子（Fuji IX、Ketac Molar、Ketac Silver和Miracle Mix）、树脂改性玻璃离子（Fuji II LC Improved、Photac-Fil和Vitremer）、复合材料（Compoglass、Dyract AP、F2000和Hytac）和复合树脂（Ariston pHc、Solitaire、Surefil和Tetric Ceram）。抗压强度与氟释放量呈负线性相关（r(2) = 0.7741），即氟释放量高的修复材料力学性能较低。氟化物释放能力可以通过局部使用氟化物剂部分再生或重新充电。总体而言，初始氟化物释放量越高的材料，其补给能力越强（r(2) = 0.7088）。用5个方程进行了曲线拟合，描述了不同材料的累积氟释放量。方程[F](c) = [F](I)(1 - e(-bt)) + betaroott最能描述大多数玻璃离子单体、树脂改性玻璃离子单体和一些高氟化物释放的组分和复合材料的累积氟化物释放量，而[F](c) = [F](I)/(t(1/2) + t) + alpha最能描述大多数组分和复合树脂的累积氟化物释放量。本文还讨论了不同释氟材料的临床应用。2003爱思唯尔科学有限公司版权所有。
The compressive strength, fluoride releases and recharge profiles of 15 commercial fluoride-releasing restorative materials have been studied. The materials include glass ionomers (Fuji IX, Ketac Molar, Ketac Silver, and Miracle Mix), resin-modified glass ionomers (Fuji II LC Improved, Photac-Fil, and Vitremer), compomers (Compoglass, Dyract AP, F2000, and Hytac) and composite resins (Ariston pHc, Solitaire, Surefil and Tetric Ceram). A negative linear correlation was found between the compressive strength and fluoride release (r(2) = 0.7741), i.e., restorative materials with high fluoride release have lower mechanical properties. The fluoride-releasing ability can be partially regenerated or recharged by using a topical fluoride agent. In general, materials with higher initial fluoride release have higher recharge capability (r(2) = 0.7088). Five equations have been used in curve fitting to describe the cumulative fluoride release from different materials. The equation [F](c) = [F](I)(1 - e(-bt)) + betaroott best describes the cumulative fluoride release for most glass ionomers, resin-modified glass ionomers, and some high fluoride-releasing compomers and composites, whereas [F](c) = [F](I)/(t(1/2) + t) + alphat best describes the cumulative fluoride release for most compomers and composite resins. The clinic applications of different fluoride-releasing materials have also been discussed. (C) 2003 Elsevier Science Ltd. All rights reserved.
