Objective: This study examined the characteristics of flowable composite-resins containing improved S-PRG filler. Materials and Methods: The tested materials were Beautifil High flow F10 (BF10-resin) and Beautifil Low Flow F02 (BF02-resin), both of them containing improved S-PRG filler, and the control materials were Unifil Flow (Un-resin) and Metafil Flo (Me-resin). Resin blocks were prepared using a metal mold followed by their bonding on both upper first molars. The blocks were debonded at 8, 12 and 24 hrs, respectively and antiplaque test was carried out including SEM observation and energy dispersive X-ray micro analysis. Furthermore, observation of saliva proteins on each resin surface and albumin adsorption probe was performed. Concerning the cavity wall adaptability test, cavities were prepared in two different manners: by Er: YAG laser and diamond burr mounted in a high-speed hand-piece. Then the preparations were filled with the corresponding material according to each manufacturer's recommendation and the cavity wall adaptability was analyzed. Results: One of the most important findings was that BF10 and BF02-resing exhibited almost no bacterial adhesion. The energy dispersive X-ray micro analysis revealed the presence of elements such as Al, Si, and Sr of the improved S-PRG filler. Also, only in BF10 and BF02-resins the film layer was observed on their surfaces soaked in albumin solution. The albumin adsorption was higher in BF10 and BF02-resins than control materials. Overall, the cavity wall adaptation was suitable for all materials, unless BF02-resin showed a creck when the cavity was prepared by Er: YAG laser. Conclusions: BF10 and BF02-resins presented appropriate characteristics and were useful for the treatment of caries; moreover they offered an anti-plaque property suggestion that the application of these materials is suitable as a minimal intervention approach.
