Abstract :

Aim To evaluate the fracture resistance of maxillary premolars obturated with different adhesive root filling materials and restored with different adhesive restorative materials. Methodology 120 extracted maxillary premolars were selected. Standardized access cavities were prepared and root canals were instrumented using rotary files (taper 4%). Samples were divided into 6 groups (n=15): Group 1: ActiV GP (AGP) + Silorane based Composite (Comp), Group 2: ActiV GP + Nano filled Resin modified glass ionomer cement (nRMGIC), Group 3: ActiV GP + Temporary restorative material (Temp), Group 4: RealSeal (RS) + Silorane based Composite, Group 5: RealSeal + nRMGIC, Group 6: RealSeal + Temp, Group 7: unobturated teeth Group 8: Intact teeth.The specimens were mounted in Instron and compressive force applied at a crosshead speed of 1 mm/min.The data so obtained was statistical analysed using Student ‘t’ test and one way ANOVA test. Results. The mean values were 872.87 N, 676.47 N, 630.07 N, 578.53 N, 539.60 N, 482.33 N, 481.07 N, 293.80 N for group 8, group 2, group 4, group 5, group 1, group 3, group 6, group 7 respectively with significant difference between the groups. Conclusions ActiV GP and RealSeal can be regarded as a viable choice to increase the fracture resistance of endodontically treated teeth. nRMGIC and silorane based composite showed nearly similar reinforcement.
