Abstract

Composite resin is the most commonly used restoration material today, as it is one of the most tooth-coloured materials. In ad-dition, the hardness factor is indispensable for the durability of the filling. The hardness of the composite can be affected by the way the material is applied. This study compared bulk-fill and non-bulk-fill nanofiller composite resins with thicknesses of 2 mm, 4 mm and 6 mm. Laboratory experimental research with posttest with control group design used 24 composite resin sam-ples divided into 6 groups, namely bulkfill and non-bulkfill nanofiller composite resins, each made with a thickness of 2 mm, 4 mm, and 6 mm. The hardness was tested with a Vicker hardness tester. The least significant deference test showed that there was a significant difference in hardness between the 6 treatment groups (p<0.05). The highest hardness was obtained by the bulkfill nanofiller composite resin with a thickness of 2 mm at 27.82 VHN and the non bulkfill composite resin showed a low hardness value especially at a thickness of 6 mm at 6.75 VHN. It is concluded that the bulkfill nanofiller composite resin has higher hardness than the non bulkfill composite resin.
