GC Essentia is a light-cured, radiopaque universal composite restorative built around a simplified shade and layering concept.GC describes Essentia as a shift from traditional monochromatic shade systems toward reproducing the ageing characteristics of enamel and dentin in 2 layers. The system uses 7 syringes to cover aesthetic restorative cases.Indications and use Anterior restorations can be layered by patient age, from bleach or junior restorations through young, adult, and senior teeth. Posterior restorations can use natural duo-layering, or Universal alone for many mono-shade situations. Masking Liner is designed for deep discoloured cavities. Official advantages 7-shade concept designed to solve clinical cases with reduced inventory. Dentin and enamel shades use different compositions for natural optical behaviour. Dentin shades are opaque enough to mask the preparation line without an extra opaque shade. Enamel shades are more compact and support gloss; Universal is packable for posterior use. Polishing is simplified to a few steps for long-term gloss retention.
