Objectives: The aim of this study was to evaluate the fracture resistance of endodontically-treated teeth restored with nano-hybrid composite resin, bulk-fill flowable and short fibre-reinforced-composite in the absence/presence of retention slots. Materials and methods: One hundred and ten extracted non-carious human mandibular molars received endodontic treatment followed.
