OMNICHROMA composite resin showed excellent visual color matching, comparable to traditional multi-shade composites. Instrumental analysis revealed differences, but OMNICHROMA offers a versatile option for esthetic dental restorations.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Esthetic Dentistry
Background:
- Accurate color matching is crucial for esthetic dental restorations.
- Universal shade composite resins aim to simplify shade selection.
- Comparing universal shade composites to established multi-shade systems is essential.
Purpose of the Study:
- To evaluate and compare the color matching of OMNICHROMA (OM), a universal shade composite, to 3M Filtek Z350 (FT) composites.
- To assess both instrumental (ΔE) and visual color matching.
- To determine the clinical applicability of a universal shade composite.
Main Methods:
- An in vitro study utilized 80 extracted permanent teeth.
- Teeth were restored with OM or FT (shades A3, A3.5, B2) in Class V preparations.
- Color matching was assessed using spectrophotometry (ΔE) and visual scoring by trained observers.
Main Results:
- Visual assessments revealed no significant differences in color matching across all groups.
- Instrumental analysis (ΔE) showed significant differences (p < 0.0001).
- OM exhibited higher ΔE values than FT shades A3.5 and B2, but not A3.
Conclusions:
- OMNICHROMA demonstrates excellent visual color matching, comparable to multi-shade composites.
- Despite higher instrumental ΔE values versus some shades, OM effectively blends visually.
- OMNICHROMA presents a versatile and reliable option for achieving satisfactory esthetic outcomes in restorative dentistry.

The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
