Abstract

Aim:  To compare and evaluate the fracture resistance of reattached incisor fracture fragment using three different restorative materials. Materials and method: Sixty recently extracted sound human maxillary permanent central incisors were randomly divided into 4 experimental groups of 15 teeth each: Group A - comprising sound/unprepared teeth (control). Group B - comprising of teeth reattached with nanocomposite. Group C - comprising of teeth reattached with fibre reinforced micro hybrid composite and Group D – comprising of teeth reattached with fibre reinforced nanocomposite. Fracture resistance was then measured under universal testing machine and compared with that of sound teeth. Results: Statistically significant difference was observed between control group, nanocomposite group, fibre reinforced microhybrid group and fiber reinforced nanocomposite group in the mean fracture resistance as well as within the groups. Conclusion: From the results and observation obtained, it can be suggested that, fibre reinforced nanocomposite is a better material for reattachment of fractured teeth fragment and it also provides better esthetics and longevity of the restoration.
