Abstract

Background: To compare the comparing the tensile bond strength of two different luting cements (Zinc phosphate and Zinc polycarboxylate) used in dentistry Materials & methods: 40 freshly extracted maxillary first premolars were included in the present study. After thorough cleaning, all the specimens were stored in normal saline till further use. After finishing of the cavity preparation, impression was taken of all the specimens followed by pouring of casts with type IV dental stones. Wax patterns were made and casting was done. Afterwards, the castings were devested, finished and polished. All the specimens were divided into three study groups as follows: Group A: Zinc phosphate group, and Group B: Zinc polycarboxylate group. Universal Testing Machine was used for evaluation of mean tensile strength. Results: Mean tensile strength of specimens of Group A, and Group B was found to be 1.88 MPa and 1.51 MPa respectively. While analysing statistically, significant results were obtained on comparing the mean tensile strength in between group A and group B. Conclusion: Mean tensile strength of Zinc phosphate cement is significantly higher in comparison to Zinc polycarboxylate group.
