Aim: To compare the tensile bond strength of Resin cements and Glass ionomer luting cements. Materials & methods: In this study, we collected 50 extracted incisors and prepared them for testing. After extraction, each specimen was thoroughly washed and dried, then stored in containers with normal saline to ensure preservation. Impressions of the specimens were taken following cavity preparation, and castings were subsequently made using dental stones. This casting process involved creating wax patterns, followed by devesting, finishing, and polishing. For the analysis, the specimens were randomly assigned to one of three groups: Group A was treated with Resin cement, while Group B received glass ionomer cement. The tensile strength of each specimen was measured using a Universal Testing Machine. The resulting data was recorded in an Excel spreadsheet and analyzed statistically using SPSS software, with significance levels determined through Student's t-tests. Results: Group A (resin cement) showed a mean tensile strength of 3.02 MPa with a standard deviation of 0.49, while Group B (GIC cement) had a mean tensile strength of 2.63 MPa and a standard deviation of 0.43. The p-value of 0.0005 indicates a statistically significant difference between the two groups. Conclusion: resin cement demonstrates superior tensile and bond strength compared to GIC and its variants, highlighting its potential as a preferred choice in dental restorations. Key words: resin, cement, strength
