| Sumario: | All-ceramic restorations represent the fundamentals of contemporary esthetic dentistry. Adhesive dentistry has revolutionized clinical techniques for the preparation, longevity, appearance, and restoration of dental work. This study sought to assess the effects of heated hydrofluoric acid pretreatment and the influence of the application technique on the surface morphology and roughness of leucite-reinforced glass-ceramic materials. Understanding these factors is significant for comprehending the adhesive cementation process. The efficiency of the two HF application strategies and the influence of HF’s temperature on the surface topography of the ceramic was observed using Scanning Electron Microscopy. On the prepared ceramic samples, resin cement was applied and light-cured in accordance with the surface conditioning techniques. The shear bond strength values were associated with the micro-retentive surface topography of the ceramic material. The SBS values between the resin cement and the ceramic material were evaluated using universal testing equipment. By utilizing digital microscopy to examine the affected surfaces of the specimens, the failure mechanisms were classified into three distinct categories: adhesive, cohesive, and mixed failure. The data was subjected to one-way and two-way analysis of variance for statistical analysis. The findings indicate that alternate treatment procedures have an impact on the surface properties of the material. |
