Abstract: 
Aim or purpose:
To evaluate fracture resistance of endodontically treated premolars restored with different bulk-fill resin composites techniques.

Materials and methods:
Thirty endodontic first upper premolars were selected. Standardized occlusal-distal cavities were made. The selection was divided in two groups of 15 samples, G-1: Bulk-Fill resin composite (Shofu, Japan) of high viscosity, G-2: Bulk-Fill resin composite (Shofu, Japan) of low viscosity, this was used as base, and the Bulk-Fill (Shofu, Japan) resin composite of high viscosity in the occlusal surface. The samples were subjected to compressive forces using the universal testing system (MTI-2K).

Results:
The difference between the mean of the maximum strength was not statistically significant, the mean force and resistance to fracture for group G-1 was 561.32N, and for the group G-2 was 567.17N.

Conclusions:
The restoration technique recommended when using Bulk-Fill resin composites related to fracture resistance is the technique that uses Bulk-Fill resin composite of low viscosity flow type as base, and high viscosity composite resin in the occlusal surface.
