Abstract

Aim: The aim of this study was to access and compare fracture resistance of tooth restored with Cention-N, Zirconomer and Filtek Z350 XT.
Materials and Methods: Seventy five extracted maxillary premolar were divided into five groups; (Group I) Unprepared intact teeth, (Group II) Teeth with class II mesio-occluso-distal (MOD) cavity prepared and unrestored, (Group III) Teeth with class II MOD cavity prepared and restored with Zirconomer (Shofu Inc), (Group IV) Teeth with class II MOD cavity prepared and restored with Cention N, (Group V) Teeth with class II MOD cavity prepared and restored with Universal Composite Restorative Material (Filtek Z350 XT). Specimen was individually tested in a universal testing machine for facture resistance.
Results: Filtek Z350 XT showed statistically significant fracture resistance as compared to Group II, Group III and Group IV (P<0> Conclusion: All the test restorative material showed acceptable fracture resistance under load. Long term clinical evaluation is required to access their behavior intraorally.
