Abstract

Light-transmitting fiber posts are recognized to potentially improve the cements polymerization, thus potentially improving the bonding of the endodontics restoration. However, different posts generally have completely different light transmission, hence it is important to be able to compare their optical performances. In this paper a simple measuring system able to compare the exitance generate by different light-transmitting fiber posts is proposed. The described measuring system is based on a microscope and a digital camera coupled to its optics. A simplified calibration and a detailed measurement procedure are described and investigated. Then, data obtained from the analysis of some commercial light-transmitting fiber posts are reported and briefly discussed. Even though, mechanical properties, biocompatibility and aesthetics have to be taken into account once choosing the post, the data provided by the proposed measuring system may support in choosing the post and, defining the proper light-source power and exposure duration.

一种简单的测量系统和校准方法，用于研究光纤传输桩的透光能力

光传输纤维桩具有改善骨水泥聚合的潜力，从而有可能改善根管修复体的粘接。然而，不同的光柱通常具有完全不同的透光性，因此能够比较它们的光学性能是很重要的。本文提出了一种简单的测量系统，可以比较不同传输光纤柱产生的出射度。所描述的测量系统是基于一个显微镜和一个数字相机耦合到它的光学系统。描述和研究了一种简化的校准和详细的测量程序。然后，报告了对一些商业传输光纤桩的分析数据，并进行了简要的讨论。尽管在选择贴片时必须考虑机械性能、生物相容性和美观性，但拟议测量系统提供的数据可能支持选择贴片，并定义适当的光源功率和曝光时间。
