Purpose: To evaluate and compare the shear bond strength and color stability post thermocycling of two commercially available intraoral porcelain repair systems used for the repair of adhesive and cohesive fracture defects in porcelain fused to metal samples. Materials and methods: Ninety-six test samples were divided into Group I (n = 56) for shear bond strength testing and Group II (n = 40) for testing of color stability after thermocycling. Each group was further subdivided based on the repair kit used: Angelus ceramic repair kit and PrevestDenPro A.C.E ceramic repair kit for the repair of adhesive or cohesive defect fracture. Shear bond strength was tested using a universal testing machine. Color values were recorded using a spectrophotometer before and after thermocycling. Inferential statistics using one-way ANOVA test followed by Tukey's honest significant difference test was used to check difference between the subgroups. An unpaired t-test was used to compare means between two subgroups. Results: The highest mean shear bond strength was observed with PrevestDenPro A.C.E. ceramic repair kit for adhesive defects (13.39 ± 0.66 MPa; p-value < 0.001). The highest color stability was observed with Angelus ceramic repair kit for cohesive defects (with mean L, a, b values before thermocycling being 73.79 ± 2.83, 6.75 ± 0.86, and 10.73 ± 1.58, respectively, and after thermocycling 75.18 ± 2.61, 7.18 ± 0.76, and 9.45 ± 1.69, respectively, thereby giving a ΔE value of 2.44 ± 0.17; p-value < 0.001). Conclusion: From the present study, it can be concluded that for an adhesive defect, PrevestDenPro A.C.E ceramic repair kit has the better mean shear bond strength and Angelus ceramic repair kit has better color stability. For a cohesive defect, Angelus ceramic repair kit has a better mean shear bond strength and color stability. A careful consideration of the type of defect while choosing the repair system is crucial for better repair outcomes.
