In Vitro Comparison of Color Matching: Universal Shade Composite Resin vs Multi-shade Conventional Composite.

Abstract

Aim: This study aimed to evaluate and compare the color matching of OMNICHROMA (OM), a universal shade composite, to the well-established 3M Filtek Z350 composites (FT).

Materials and methods: An in vitro experimental study was conducted on 80 freshly extracted permanent teeth, with intact buccal surfaces. The teeth were randomly assigned to four groups: Group I OM and groups II, III, and IV (3M Filtek Z350 in shades A3, A3.5, and B2, respectively). Class V cavity preparations were created and restored using the respective composites. Color matching was assessed instrumentally using a spectrophotometer to calculate the color difference (ΔE) values and visually by three trained observers using a standardized visual scoring system.

Results: Visual assessments showed no significant differences in color matching across the four groups. However, the ΔE color matching analysis revealed significant differences (p < 0.0001), with OM exhibiting higher ΔE values compared to FT shades A3.5 and B2. No significant difference was found between OM and shade A3.

Conclusion: OMNICHROMA demonstrated excellent visual color matching, comparable to the various shades of FT composites. Despite the higher ΔE values observed instrumentally in comparison to shades A3.5 and B2, OM's ability to blend with different tooth shades visually was highly effective.

Clinical significance: These results suggest that OM offers a versatile and reliable option for achieving satisfactory esthetic outcomes, reducing the need for multiple shade variations in restorative procedures.
