“…The maximum loads in compression that were recorded, in the present study, for flowable bulk‐fill (SDR) and fiber‐reinforced (everX) composites are in line with those reported in a similar study by Ö zyürek et al . , who utilized the same materials to restore endodontically treated teeth. It was observed that even though the fiber‐reinforced composite groups did not demonstrate the highest fracture loads, they had fractures that could be more easily restored .…”

This study aimed to evaluate the effect of different interface designs on the load‐bearing capacity of bilayered composite structures (BLS). Cylindrical specimens of BLS were prepared from base composite of 3.5 mm thickness and surface composite of 1.5 mm thickness (n = 80). Two different base composites – flowable bulk‐fill (FBF) [smart dentin replacement (SDR)] and short fiber‐reinforced (FRC) (everX Posterior) – were evaluated, and conventional composite (G‐ænial Posterior) was used as the surface layer. Four different interface designs were used: (i) pyramidal; (ii) mesh; (iii) linear grooves; and (iv) flat surface (control). Three‐dimensional printed molds were fabricated to standardize the interface design between the surface and the base composites. The specimens were then statically loaded with a steel ball until fracture using a universal testing machine. Fracture types were classified into catastrophic, complete, and partial bulk. ANOVA revealed that both the material and the interface design had a statistically significant effect on the load‐bearing capacity. Flowable bulk‐fill showed lower mean load‐bearing capacity than FRC in all the interface designs tested, except for the flat surface design. Fracture analysis showed that FRC demonstrated up to 100% partial bulk fractures with the pyramid interface design, but no incidence of catastrophic bulk fracture. By contrast, FBF demonstrated up to 84.6% and 40% catastrophic bulk fractures with the flat interface design but no incidence of partial bulk fracture. Consequently, the interface designs studied enhanced the fracture behavior of BLS.

“…Enquanto algumas pesquisas observaram não haver diferença na resistência à fratura quando da realização de cavidades endodônticas tradicionais e conservativas para dentes anteriores (KRISHAN et al, 2014) e posteriores (MOORE et al, 2016;CHLUP et al, 2017;ROVER et al, 2017;OZYUREK et al, 2018), estudos têm demonstrado que a cavidade endodôntica conservativa confere maior resistência à fratura que a cavidade endodôntica convencional em dentes posteriores (KRISHAN et al, 2014;PLOTINO et al, 2017).…”

“…A partir disso, estudos têm sido realizados com o objetivo de avaliar o impacto da cavidade endodôntica conservativa no preparo biomecânico (KRISHAN et al, 2014;MOORE et al, 2016;NEELAKANTAN et al, 2017;ROVER et al, 2017;ALOVISI et al, 2018a;OZYUREK et al, 2018), bem como no procedimento restaurador (MOORE et al, 2016;CHLUP et al, 2017;PLOTINO et al, 2017;ROVER et al, 2017;OZYUREK et al, 2018;SILVA et al, 2018). Dessa maneira foi avaliado, no presente estudo, o impacto da cavidade endodôntica conservativa no preparo biomecânico com diferentes sistemas de instrumentação, bem como o efeito de diferentes materiais restauradores no comportamento biomecânico de pré-molares superiores submetidos ao tratamento endodôntico.…”
