“…This occurs at a denaturation temperature that differs between the different organization levels of collagen tissue. The denaturation temperature of fully hydrated soluble collagen is near body temperature; it is considerably higher in disordered precipitated collagen (50 • C), and even higher in assembled fibrous collagen tissue (~60 • C) [26,27].…”

This study investigated the effect of 3 s light-curing with a high-power LED curing unit on the shear bond strength of bulk-fill composites. Four bulk-fill composites were bonded to dentin with a universal adhesive (Scotchbond Universal Plus): two materials designed for rapid curing (Tetric PowerFill and Tetric PowerFlow) and two controls (Filtek One Bulk Fill Restorative and SDR Plus Bulk Fill Flowable). The 4 mm composite layer was light-cured with Bluephase PowerCure for 20 s at 1000 mW/cm2 (“20 s”) or for 3 s at 3000 mW/cm2 (“3 s”). The samples were stored at 37 °C in distilled water and tested after 1, 6 and 12 months. The samples polymerised in the “3 s” mode had statistically similar or higher bond strength than the samples cured in “20 s” mode, except for the Tetric PowerFlow (1 month) and SDR+ (6 month). The flowable materials Tetric PowerFlow and SDR Plus initially showed the highest values in the “3 s” and “20 s” groups, which decreased after 12 months. The bond strength was statistically similar for all materials and curing protocols after 12 months, except for Tetric PowerFill cured with the “3 s” protocol (21.22 ± 5.0 MPa), which showed the highest value. Tetric PowerFill showed the highest long-term bond strength. While “3 s” curing resulted in equal or better shear bond strength, its use can only be recommended for a material with an AFCT agent such as Tetric PowerFill.

Objective: Non-carious cervical lesions (NCCLs) are commonly observed in clinical dentistry, leading to tooth fractures, sensitivity, and compromised pulp vitality. Therefore, their restoration is essential for both the aesthetic and structural integrity of teeth. This study aimed to compare the fracture resistance of NCCLs restored using different materials: an injectable universal composite, flowable bulk-fill composites with or without fiber-reinforcement. Methods: Seventy-five double-rooted maxillary premolars were selected for the study. Fifteen teeth were left intact as a control. A wedge-shaped cavity was prepared in the cervical region of the remaining sixty teeth, which were then divided into four groups ( n = 15): unrestored, restored with an injectable composite, restored with a flowable bulk-fill composite (SDR® flow+), and restored with a flowable short-fiber-reinforced composite (everX Flow™). All teeth underwent fracture testing under oblique static loading at a 30° angle using a universal testing machine. Fracture patterns were classified as repairable, possibly repairable, or unrepairable. Data were analyzed using one-way analysis of variance, Pearson chi-square, and Tukey HSD post hoc tests ( p = 0.05). Results: Intact teeth exhibited the highest fracture resistance (743.481 N), while unrestored teeth showed the lowest (371.49 N) ( p < 0.001). There was no significant difference in fracture resistance between the injectable composite (553.289 N) and SDR® flow+ (497.368 N) ( p = 0.055). The everX Flow™ group displayed significantly higher fracture resistance (673.787 N) ( p < 0.001) and a repairability rate of 60% within the restored groups. Unrestored (60%), injectable composite (53.3%), and SDR® flow+ (53.3%) groups were mostly unrepairable. Conclusion: The everX Flow™ demonstrated improved fracture resistance and favorable fracture pattern for maxillary premolars with wedge-shaped NCCLs.
