OBJECTIVE: To evaluate the influence of adhesive curing mode and composite viscosity type on the fracture resistance of reattached anterior teeth using the internal groove technique.
MATERIALS AND METHODS: Seventy-two extracted human maxillary central incisors were fractured using a standardized protocol and randomly assigned to six groups according to adhesive curing mode (light-cure, self-cure, and dual-cure) and composite viscosity type (flowable and packable) (n = 12). Fragments were reattached using standardized procedures. All specimens were subjected to thermocycling (5000 cycles) and fracture resistance was measured using a universal testing machine. Fracture resistance recovery (%) was calculated. Data were analyzed using two-way ANOVA and Tukey post hoc tests (α = 0.05).
RESULTS: Both adhesive curing mode and composite viscosity type significantly influenced fracture resistance (p < 0.001), while no significant interaction between factors was observed (p > 0.05). The highest fracture resistance recovery was observed in the dual-cure packable group, whereas the lowest values were recorded in the light-cure flowable group. Packable composites demonstrated higher fracture resistance than flowable composites across all adhesive curing modes.
CONCLUSION: Dual-cure adhesives combined with packable composites demonstrated the highest fracture resistance, whereas light-cure adhesives with flowable composites demonstrated the lowest values.
CLINICAL SIGNIFICANCE: Dual-cure adhesives combined with packable composites demonstrated higher fracture resistance in fragment reattachment procedures.
