single shade universal resin composite (omnichroma) with blockersingle-shade universal resin composite (omnichroma) with blocker( omnichroma blocker)(OMNICHROMA BLOCKER) is indicated for preventing shade-matching interference in Class IV restorations, Masking dark dentition and dentin. In cases where there is a lack of tooth structure to bond to, (BLOCKER) works as a supplementary product to provide a lingual wall to the restoration, prevent shade-match obstruction and mask staining.
single shade universal resin composite(GC solare sculpt) with chameleon effectsingle-shade universal resin composite (omnichroma) with blocker( omnichroma blocker)One-shade universal resin composite (GC solare sculpt) gives very natural appearance, High gloss retention over time, time saving regarding to layering technique, wide shade matching range (chameleon effect) and delivering lifelike aesthetic restorations. These features can be offered by supra-nano spherical filler which have controlled refractive index, records excellent esthetic properties in small and medium class IV restorations.
Primary Outcome Measures

the shade matching of both groups will be assessed visually by using modified USPH criteria.

score: 1- Alpha : the restoration match the shade and translucency of the adjacent tooth 2-Bravo : there is a mismatch in the shade and translucency but it is within a normal range of tooth shade 3- Charlie: the mismatch is beyond the normal range of the tooth shade and translucency
