Biological properties comparison of Short-fiber Reinforced Composite with two bulkfil composites
Objectives: Recently using dental composite resins as a restoration material in the stress bearing area cavities attracted more dentist attention. In order to improve the resin matrix of composite resins, GC Corporation has introduced new short-fiber reinforced composite. The purpose of the present study was to evaluate biological properties of short-fiber reinforced composite in comparison with two bulk-fill composite resins intended for posterior large restorations, Filtek-Bulkfil and Beautifil-Bulk.
Methods: Cell study was done to evaluate the cytotoxicity of the samples. All the samples were made in clean bench. They were divided into four groups and were kept in clean bench in room temperature for 24 hours. All the samples were put in 96 well dish and 20000 of MC3T3E1 cells (Osteoblast like cells) were added in each well. In days 2-4-6, MTS assay was added to the samples and after 3 hours they were put in plate reader to get the wavelength and measure cell numbers. Statistical analysis was used to evaluate the experimental results. SEM images were taken to compare cell morphology on each specimen.
Results: As the result, all polished composite resins showed less cytotoxicity. On the other words, the polished surfaces showed better viability result compare to the non-polished samples. Filtek-Bulkfil had the greatest proliferation among all samples, against the Beautifil-Bulk that had the lowest cells proliferation.
Conclusions: In conclusion, barium glass fiber as filler did not decrease the viability compare to the other composite resins.
