Abstract

In the field of dental color research, there are observing color of natural teeth, analysing color spectrum of human natural teeth, researching discoloration of teeth, and researching shade-guide of teeth. However, there is less research for fluorescence which is optical shade than research for the color which can be seen. In this research, fluorescent standard materials in that 7-Diethylamino-4-methylcoumarin which is used universally to fluorescent high polymer dental restoration materials was blended were made in the concentration from 0.01% to 0.1%. 14 kinds of composite resin and fluorescent standard materials were observed on Bio Imaging systems and Fluor chern E which is Fluorescence image analyzer, and fluorescence of specimens was analysed measuring gray level of specimen by Image J and Photoshop which is Monochrome color analysis software. Analysing Standard curve graph, fluorescent concentration of specimen in the fluorescent standard materials concentration between 0.01∼0.1% in composite resin could be calculated. Depending on the combination of fluorescence image analyzer and monochromatic analysis software in all the experimental groups except the Filtek Z250 A3.5, showed a significant difference(P<0.05). Among them, in all experimental groups of GC GRADIA DIRECT, showed the highest difference significance of the fluorescence concentration due to monochromatic analysis software(P<0.05).
