摘要
可见光固化树脂已广泛应用于牙科临床。为了改进树脂性能,需对不同配方的材料进行选择,这就要建立各种比较评价的方法。本文所述付里叶变换红外吸收光谱法(FTIR)是一种方便、实用的方法,可出牙釉质粘合剂中双的反应情况,由其变化温度及最终的殘率可推断材料的组成与结构,结合对材料其它性能的测定,能为各种体系的比较提供依据。
The light cure composite has been widely used in dental treatment. To improve the performance of the composite, special care should be taken to select the right materials for different ingredients, and a comparative evaluatisn methodology has to be developed. The FTIR absorption spectrum method is introduced as a convenient and practical way to measure the reaction condition of double bond in dental enamel adhesive. The composition and construction of the material can be inferred from the speed of reaction of double bond and its rate of final remains. This measurement. together with other performance measurements of the material, can provide basic data for the comparison.
