Background: Testing the Tensile Bond Strength of Dental Luting Cements: Zinc Phosphate vs. Zinc Polycarboxylate. Materials & methods: In this study, fifty 2ndpremolars extracted from freshly excised maxillaries were collected and prepared for testing. After washing and drying, each specimen was stored in normal saline for future use. Impressions were taken of all specimens following cavity preparation, and castings were poured using type IV dental stones. The casting process involved creating wax patterns, followed by devesting, finishing, and polishing the castings. Subsequently, the specimens were randomly assigned to one of two groups: Group A, treated with zinc phosphate, and Group B, treated with zinc polycarboxylate. The average tensile strength of each group was then measured using a Universal Testing Machine. Results: The average tensile strength of Group A specimens was measured at 2.34 MPa, whereas Group B specimens averaged 1.86 MPa. Upon comparing the average tensile strength of samples from Groups A and B, statistically significant differences were observed. Conclusion: The study revealed a statistically significant difference in the mean tensile strength between the Zinc phosphate and Zinc polycarboxylate groups, with the Zinc phosphate group exhibiting a significantly greater mean tensile strength.
