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.

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.
