초록/요약
The purpose of this study on a light-cured composite were to design a testing procedure in which the degree of conversion could be controlled and measured in a filled composite while not subjecting the specimen to grinding or polishing in order to eliminate variables affecting solubility and conversion and to preserve the specimen for further parameter testing. Also, this study was to compare the three different in vitro techniques (i.e., surface microhardness, KBr-pellet and thin film for FTIR) used to determine the degree of conversion of light-cured composite resins. From this experiment, the following results were obtained : 1. Compare with depth cure, uncured monomer amount increased at more than 2mm depth in FTIR 2. The microhardness was reduced as depth increased. 3. This study compared KBr-pellet, thin film and microhardness methods and found that these methods were significant correlation. These results revealed that FTIR and microhardness methods seem to provide useful results for degree of conversion. The thin film method developed allowed samples of light-cured composite to be made with controlled conversion for parameter testing, and eliminated effects of resin lost to slurry during polishing or an increase in conversion as a result of heat generated during grinding.
