Background: The present study was conducted for comparatively evaluating the tensile bond strength of 2distinct luting cements (Zinc phosphate and Zinc polycarboxylate) used in dentistry. Materials & methods:100 freshly extracted maxillary first premolars were utilized. To be used later, the samples were all carefully cleaned and stored in sterile saline. After the cavity preparation was completed, castings consisting of type IV dental stones were put into each specimen. For casting, wax patterns were utilized. Two study groups were formed: Group A is composed of zinc phosphate, whereas Group B is composed of zinc polycarboxylate. The mean tensile strength was measured using a universal testing apparatus. Results:The specimens belonging to Group A and Group B were found to have mean tensile strengths of 3.23 MPa and 2.99 MPa, respectively. Significant findings were found when comparing the mean tensile strength between groups A and B by statistical analysis. Conclusion:It had been concluded that the mean tensile strength of Zinc phosphate cement is much higher as compared to Zinc polycarboxylate cement.
