Over the past few years, there has been a growing trend of patients requesting or expecting high aesthetic restoration. Color stability is an essential clinical aspect when it comes to the aesthetics which in turns affect the long-term clinical success of resin-based ceramic restorations. Plaque accumulation, solution stains, surface roughness, and chemical reactions can all affect the color of these materials [As instrumental color measurement has the advantages of being objective and quantified, CIE lab formula was selected in the current study to determine any color changes [Previous research on hybrid materials has mostly concentrated on mechanical qualities [Currently, there is no published clinical trial research on the color stability of resin-ceramic infiltrated materials. Therefore, this study compared the color stability of two resin hybrid ceramic restorations in randomized clinical trial. Founded on the study outcomes, the null hypothesis stated was accepted since the color stability of Vita Enamic was comparable to that of Cerasmart hybrid ceramic; with no statistically significant difference after one year of clinical service and all was within the clinically acceptable range of color difference (ΔE > 3.3) [The results of the current study compared color alterations in two dental materials over a period of 6, 12 months and the total change. The findings showed that the Vita Enamic group significantly higher than the Cerasmart group in terms of ΔL* (lightness) and, Δa* (hue) values at 6-month intervals, whereas there was no significant difference in Δb* (color tone) and E (overall color difference) values between both groups with a Difference in materials color stability across the research timeline could be endorsed to differences in composition and microstructure [Additionally, the sustainability of a restoration’s color is mainly influenced by the type of resin matrix, as water absorption by the resin component of the material is a major contributing factor to color changes [Saba et al. [In the same context, Sarikaya et al. [In addition, Materials can experience color changes due to many factors such as abrasion, erosion, exposure to saliva, food, and drinks [At the end, both groups revealed statistically insignificant variations in color stability, proving that both materials underwent color change. This might imply that both materials’ color stability would be compromised over a longer time frame. Even though the differences may be slight and invisible to patients or clinicians and within clinically acceptable range [
