Summary:Study was done to evaluate and compare the impact strength of reattached fractured incisor tooth using five different adhesive materials 1) Composite 2) Giomer 3) Dual Cure Resin Cement 4) Resin Modified GIC 5) Compomer. Ninety sound freshly extracted human permanent incisors were selected according to the inclusion criteria. 15 teeth were taken as a control (Group I) and remaining 75 teeth were divided equally and randomly into five Groups; Group II - Composite, Group III - Giomer, Group IV - Dual Cure Resin Cement, Group V - Resin Modified GIC, Group VI - Compomer based upon the materials to be used for reattachment. The specimen teeth in the experimental groups were fractured by Custom-made vice. The fractured fragments were reattached using their respective adhesive materials. Then the impact resistance was recorded in an impact testing machine and data was analyzed. On comparing the mean impact strength by using One Way ANOVA and Unpaired 't' test it was observed that statistically highly significant difference was present when comparison was made between mean impact strength of intact teeth and reattached fractured teeth. Statistically highly significant difference was obtained on comparing impact strength of intact tooth with reattached tooth using adhesive materials. So, no material studied was able to attain the impact strength of intact tooth. However, when materials were compared, decreasing order of their impact strength was Compomer > Composite > Dual Cure Resin Cement > Giomer > Resin Modified GIC.
