| Popis: | 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 |
