| Abstract | ||||
| Aim: This study aimed to compare the fracture resistance of endodontically treated premolars restored by Ceram x SphereTEC one composite resin, bioactive restorative material (ACTIVA BioACTIVE Restorative), Alkasite restorative material (Cention-N) and Zirconia reinforced glass ionomer (Zirconomer). Subjects and Methods: Forty maxillary premolars were assigned into four equal groups according to the restorative material used . Group A: Teeth restored with Ceram x SphereTEC one. Group B: Teeth restored with ACTIVA BioACTIVE Restorative. Group C: Teeth restored with Cention-N and group D: Teeth restored with Zirconomer. Standardized flat MOD cavities after root canal treatment were prepared for all groups. Restorative materials were applied according to manufacture instructions. The teeth were mounted in universal testing machine and subjected to compressive force till fracture. Fracture patterns were evaluated under a stereomicroscope at magnification of 12×. Data was statistically analyzed. Results: For all groups, the mean fracture resistance values were 1447.82 N, 1452.28 N, 1250.42 N, and 920.39 N, respectively. Statistical analyses showed no significant differences in the mean fracture resistances between group A, group B and group C (p < 0.05). There were significant differences between group D and the other groups (p > 0.05). Conclusions: Ceram x SphereTEC one, Activa Bioactive Restorative and Cention-N have a high similar fracture resistances values in restoration of endodontically treated teeth, while Zirconomer has the lower value. | ||||
