Abstract

Bulk fill resins are translucent and can be light cured at depths up to 5 mm. The degree of conversion (DC) is directly related to the mechanical properties of composite resins. The aim of this study was to evaluate the DC of different types of Bulk Fill composite resins. The resins evaluated were Opus Bulk-Fill Flowable (OBFF), Opus Bulk-Fill Paste (OBFP), Filtek ™ One Bulk-Fill Restorative (FBFR) and Filtek ™ Bulk-Fill Flow Restorative (FBFF). For each group were made 3 discs with 6.0 mm in diameter and 4.0 mm depth. The discs were standardized and photoactivated for 20 seconds at the top and stored at 37ºC for 24h in a controlled light oven. The samples were analyzed by FTIR - Fourier Transform Infrared Spectroscopy. Statistical analysis was performed by one-way ANOVA followed by Tukey test (p <0.05). The top surface shows a statistical difference between FBFF and OBFF (p = 0.032) and there was no statistical difference between OBFP, OBFF and FBFR. For the base surface, there was no statistical difference between the groups. Bulk Fill resins had similar DC except for FBFF.
