Abstract

Objective: To develop a low shrinkage, hydrophobic, degradation-resistant, antimicrobial dental composite using a fluorinated acrylate, and a difunctional oxirane.

Methods: The effects of a fluorinated acrylate (2-(perfluorooctyl)ethyl acrylate; PFOEA), a difunctional oxirane (EPALLOY™ 5001; EP5001), and a three-component initiator system (camphorquinone/ethyl 4-dimethylaminobenzoate/4-Isopropyl-4'-methyldiphenyl iodonium Tetrakis (pentafluorophenyl) borate; CQ/EDMAB/Borate) on bisphenol A glycidyl dimethacrylate: triethylene glycol dimethacrylate (BisGMA:TEGDMA) composite surface hardness, degree of monomer-to-polymer conversion, hydrophobicity, translucency, mechanical properties, polymerization shrinkage and shrinkage stress, degradation, water imbibition, and antimicrobial properties were determined.

Results: Overall the experimental composites had comparable mechanical properties and lower volumetric polymerization shrinkage and shrinkage stress as compared to BisGMA:TEGDMA controls. Addition of PFOEA increased composite hydrophobicity, but it decreased degree of cure, ultimate transverse strength, and translucency. It also decreased polymerization shrinkage and shrinkage stress. The use of the CQ/EDMAB/Borate initiator system was beneficial for the cure and mechanical properties of the 30% w/w PFOEA group. However, it decreased the hydrophobicity and translucency of those composites. The addition of EP5001, at the low concentration used in this work, did not contribute to reduced polymerization volumetric shrinkage or antimicrobial properties, but it did reduce shrinkage stress.

Conclusions: A mechanically viable hydrophobic composite system with reduced polymerization shrinkage and shrinkage stress has been developed by adding PFOEA and EP5001. However, the addition of EP5001 did not render the composite antimicrobial due to the low concentration used. Further research is needed to determine the lowest concentration at which EP5001 provides antimicrobial activity. The composites developed here have the potential to improve longevity of traditional BisGMA:TEGDMA composite systems.

一种低收缩、疏水、抗降解、抗菌牙科复合材料，使用氟化丙烯酸酯和氧环烷。

目的:研制一种低收缩、疏水、耐降解、抗菌牙科复合材料，使用氟化丙烯酸酯和双官能氧环烷。方法:氟化丙烯酸酯(2-(全氟辛基)丙烯酸乙酯)的效果;PFOEA)，一种双功能氧环烷(EPALLOY™5001;EP5001)和三组分引发剂体系(樟脑醌/4-二甲氨基苯甲酸乙酯/4-异丙基-4'-甲基二苯基碘四(五氟苯)硼酸盐;测定了CQ/EDMAB/硼酸盐)对双酚A缩水甘油酯二甲基丙烯酸酯:三乙二醇二甲基丙烯酸酯(BisGMA:TEGDMA)复合材料的表面硬度、单体转化度、疏水性、半透明性、力学性能、聚合收缩和收缩应力、降解性能、吸水性和抗菌性能。结果:总的来说，与BisGMA:TEGDMA对照相比，实验复合材料具有相当的机械性能和更低的体积聚合收缩和收缩应力。PFOEA的加入提高了复合材料的疏水性，但降低了固化度、极限横向强度和半透明性。同时降低了聚合收缩和收缩应力。CQ/EDMAB/硼酸盐引发剂体系的使用有利于30% w/w PFOEA组的固化和力学性能。然而，它降低了复合材料的疏水性和半透明性。EP5001的加入，在本研究中使用的低浓度下，并不有助于降低聚合体积收缩或抗菌性能，但它确实降低了收缩应力。结论:通过添加PFOEA和EP5001，制备了一种具有降低聚合收缩和收缩应力的机械可行的疏水复合体系。然而，由于使用的浓度低，EP5001的加入并没有使复合抗菌。需要进一步研究确定EP5001提供抗菌活性的最低浓度。这里开发的复合材料有可能提高传统BisGMA:TEGDMA复合系统的使用寿命。
