Comparative Evaluation of Fracture Resistance in Pulpectomized Second Primary Molar Teeth Restored with Nanohybrid Composite Resin with and without Glass Fiber Reinforcement: An In vitro study
Year: 2025
Type: article
Abstract: Introduction: study evaluated fracture resistance in pulpectomized second primary molars restored with nanohybrid composite resin, comparing reinforcements using vertical and cross-pattern glass fibers. Materials and Methods: Sixty teeth were divided into four groups: intact teeth, composite-only restorations, and composite with cross or vertical fiber reinforcement. Results: Vertical fiber-reinforced restorations achieved the highest fracture resistance (893.5 N ± 53.2), significantly outperforming composite-only and cross-pattern reinforcement. Conclusions: Vertical fiber orientation provided superior stress distribution, making it an effective, esthetic alternative to traditional restorative techniques for pulpectomized primary molars.
