Abstract

Background:Dental luting cements (Zinc phosphate and Zinc polycarboxylate) are tested for their tensile bond strength against one another. Materials & methods:Forty first premolars from freshly excised maxillaries were used here. After being washed and dried, each specimen was placed in a container of normal saline for future use. All of the specimens had their impressions taken once the cavity preparation was complete, and then castings were poured using type IV dental stones. The casting process began with the creation of wax patterns. After that, we devested, finished, and polished the castings. The samples were randomly assigned to one of 2 categories for analysis: In Group A, we have zinc phosphate, and in Group B, we have zinc polycarboxylate. The average tensile strength was measured with a Universal Testing Machine. Results:The average tensile strength of Group A specimens was 2.01 MPa, while Group B specimens averaged 1.75 MPa. When comparing the average tensile strength of samples from groups A and B, statistically significant differences were found. Conclusion:Zinc phosphate cement had significantly greater mean tensile strength than the Zinc polycarboxylate group.
