“…The age of the subjects ranged from 43 to 58 years, with follow-up periods ranging from 3 days to 1 year [1,19,26,27]. The countries where the trials were conducted were Egypt [1,28], Brazil [27], and India [19].…”

“…The total number of patients treated and teeth restored was 141 and 236, respectively. One study included class IV restorations [28], one study included full coronal aesthetic restorations [19], one study included noncarious cervical lesions [27], and one study included occlusal restorations [1]. The restored dental elements included permanent anterior and posterior teeth and primary anterior teeth.…”

The objective was to compare the color match and color stability behavior of single and multishade resin-based composites (RBCs) used for direct restorations. This review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized clinical trials evaluating the shade performance of single-shade RBCs in direct restorations were included. A search of the scientific literature was performed in 5 databases (April 2024). The meta-analysis was performed using RevMan 5.4, calculating the risk difference (RD) and 95% confidence interval (CI) of the dichotomous outcome using a random effects model. Bias was assessed using the RoB 2.0 tool, and certainty of evidence was assessed using the GRADE tool. Four studies with 263 restorations analyzed were selected. The results showed comparable performance between single-shade RBCs and multishade RBCs in terms of color match and color stability over 12 months. Three studies had a low risk of bias with all expected results, and one study had some concerns. The certainty of evidence for color stability was considered low for all follow-up periods due to the small number of events and sample size. According to the United States Public Health Service Evaluation (USPHS) and the World Dental Federation (FDI), there is comparable clinical color performance between single-shade and multishade RBCs over 12 months.

“…It was claimed that Omnichroma possesses the ability to blend in with surrounding enamel and dentin even after bleaching, improving aesthetics and simplifying the shade matching procedure 10 . However, in previous trials Omnichroma was inferior to multishade composite systems in shade matching ability, which may hinder their use in highly aesthetically demanding areas 5 . The color stability and shade matching of resin composites is one of the most important factors determining the clinical longevity of aesthetic restorations, particularly in anterior teeth 11 .…”

“…Color has three dimensions, namely hue, chroma, and value, which are used to describe the shades of commercially available resin composites 3 . The presence of multi-shade systems may complicate the color matching process and increase chairside time and costs 4,5 . To label the shade of their products, most resin composites manufacturers use the VITA classical shade system (VITA Zahnfabrik, Sackingen, Germany), the letters A, B, C, and D represent the hue, while the numbers 1, 2, 3, and 4 represent the chroma and value 6 .…”

“…Universal shade resin composite restoration with color adjustment, blending, shifting, and assimilation potentials has been developed to replace different shades and provide shade matching for all tooth colors 7,8 . The capacity of resin composite materials to adjust their color to the color of surrounding enamel and dentin is described in esthetic dentistry by the term "chameleon effect" 5 .…”

Materials and methods:A total of 40 human sound premolars were randomly divided into two groups according to the materials' assignment either; single-shade or multi-shade composite (n=20), then each group was divided into two subgroups according to the storage medium either; distilled water or coffee (n=10) and then each subgroup was divided into two classes according to the shade either; A2 or A3 (n=5). Circular class V cavities were prepared on labial surfaces of each tooth and teeth were restored using either composites according to the manufacturers' instructions.The color of each tooth and restoration was recorded using VITA Easyshade V following aging and bleaching. The shade difference between the restoration and the tooth was calculated.Results: Intergroup comparison of ΔE and ΔE 00 between both composites have shown significant difference at baseline, one day and 12 days (P ≤ 0.05) within both storage media and shades. Intragroup comparison of ΔE and ΔE 00 within Omnichroma or Filtek Z350XT have shown statistically significant effect of time on ΔE (P ≤ 0.016). Intergroup comparison of ΔE and ΔE 00 between both composites have shown statistically significant difference before bleaching, immediately after bleaching and after two weeks (P ≤ 0.05) within both shades. Intragroup comparison within Omnichroma or Filtek Z350XT have shown statistically significant difference between different time periods (P ≤ 0.016 ).Conclusions: Multi-shade composite showed superior immediate shade matching ability as compared to the single-shade one. Both materials showed low color stability following aging and poor color matching after bleaching.
