Materials and Methods: The research sample consisted of 60 molds of composite resin (30 samples of conventional composite - 30 samples of bulk-fill composite). The sample of each material was divided into two groups (15 samples for the hardness test and 15 samples for the compressive test).

Properties: The results showed that the compressive strength of the conventional resin is more than the compressive strength of the bulk composite resin. There are no statistically significant differences between hardness of conventional composite resin and bulk composite.
