[Flexural strength of conventional flowable, bulk fill flowable and highly filled flowable resin composites: in vitro study.].

Objective: To evaluate and compare the flexural strength of conventional flowable, bulk fill flowable and highly filled flowable resins.

Materials And Methods: Thirty 2mm x 2mm x 25mm specimens of Tetric N-Flow (TNF), Filtek Bulk Fill Flowable Restorative (FBF) and Beautifil Flow Plus F00 (BFP) flowable resins were made up; they were distributed into three groups according to brand (n=10) and stored in distilled water for 24 hours at 37ºC. The 3-point bending test according to ISO 4049 was performed on a universal testing machine at a speed of 0.
