Background And Objective:
The purpose of this investigation was to estimate the impact strength of fractured anterior teeth reattached using three different restorative materials and compare their impact strengths to those of control.
Materials And Methods:
Sixty human maxillary permanent central incisors were selected and divided into control and experimental groups. The teeth in the experimental groups were fractured and then bonded using Composite resin, Compomer and resin-modified GIC. Intact teeth served as control. All the specimens were then tested in an impact testing machine.
Results:
The results revealed statistically significant differences between Compomer and resin-modified GIC groups, control and experimental groups. No statistically significant differences were observed between Composite resin and Compomer groups.
Conclusion:
Thus the fractured fragments bonded with Composite resin and Compomer provided better adhesion than resin-modified GIC.
