Abstract: Background: The aim is to evaluate the tensile bond strength of two distinct luting cements, namely Zinc phosphate and Zinc polycarboxylate, employed in dental practices.

Material and methods: In the current investigation, one hundred freshly extracted maxillary first premolars were utilized. Each sample was thoroughly cleaned and stored in sterile saline for subsequent use. After the cavity preparation was completed, castings made from type IV dental stone were applied to every specimen. Wax patterns were employed during the casting procedure. Following this, the castings were subjected to polishing, devesting, and finalization. The specimens were divided into two research groups: Group A included zinc phosphate, while Group B contained zinc polycarboxylate. The mean tensile strength was measured using a universal testing machine. The results were analyzed with SPSS software and organized into a Microsoft Excel spreadsheet. A Student's t-test was performed to evaluate the significance of the results.

Results: The samples categorized as Group A and Group B demonstrated average tensile strengths of 5.65 MPa and 4.28 MPa, respectively. Statistical evaluation indicated notable differences in the average tensile strength when comparing Group A with Group B.

Conclusion: The findings indicated that the average tensile strength of Zinc phosphate cement significantly exceeds that of Zinc polycarboxylate cement.
