Abstract Objective To evaluate the bonding strength, aging resistance, and microleakage between different bulk filling resins and dentin. Methods A total of 140 unified vitro molars were chosen(from Department of Stomatology in China Rehabilitation Research Center), 120 of which had their dentin layer revealed and covered with adhesives. They were divided into four groups by random number table method, with 30 cases in each group. The four groups were whole filled with FiltekTM Bulk Fill resin (group A), X-tra Bulk Fill resin (group B), SureFil SDR flowable resin (group C), and stratified filled with Filtek Z350 conventional resin (group D), the four groups were divided into two subgroups by random number table method, with 15 cases in each group. The first subgroup was after filling, that was before aging; the other subgroup underwent 10 000 temperature cycles of aging, that was after aging, shear strength tests were performed. The difference of bonding strength between different resin materials and before and after aging was compared by single factor analysis of variance. The remaining 20 molars were prepared into a Class Ⅰ cavity with a depth of 4 mm, with five molars in each group, filled and aged, soaked in 2% methylene dye for 24 h, cut into 1 mm slices, and the dye infiltration at the edge of the filling body was observed under a type microscope. Results Before aging, the bonding strength of group C was higher than that of groups A, B, and D, and the differences were statistically significant (P＜0.05). After aging, the bond strength of all groups decreased compared with that before aging, and the bond strength of group C was higher than that of groups A, B, and D, the differences were statistically significant (P＜0.05). There was no significant difference in interface microleakage scores among all groups (P＞0.05). Conclusion SDR with low viscosity performed well in the trial, having a better bonding effect than conventional resin.
