Comparative Evaluation of Fracture Resistance in Endodontically Treated Teeth: An Analysis of Different Restorative Materials.

BACKGROUND

Endodontically treated teeth are susceptible to fractures due to loss of structural integrity. Reinforcing these teeth with appropriate restorative materials is crucial for restoring their function and longevity. The study was undertaken to compare the fracture resistance of endodontically treated teeth restored with different restorative materials.

MATERIALS AND METHODS

This study involved five groups: a control group with no reinforcement, and four experimental groups restored with fiber-reinforced composite, bulk fill flowable composite, self-adhering flowable composite, and resin-modified glass ionomer cement (RMGIC). Single-rooted premolars were standardized and subjected to compressive forces using a Universal Testing Machine to measure their fracture resistance.

RESULTS

All restorative materials significantly improved fracture resistance compared to the control group. Bulk fill flowable composite exhibited the highest fracture resistance, followed by fiber-reinforced composite, flowable composite, and RMGIC.

CONCLUSION

The study demonstrates the importance of material selection in enhancing the fracture resistance of endodontically treated teeth. Bulk fill flowable composite was found to be the most effective in resisting fractures, suggesting its suitability for high-load-bearing applications in clinical practice.
