研究组 & 干预措施
single shade universal resin composite (omnichroma) with 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.
干预措施: single-shade universal resin composite (omnichroma) with blocker( omnichroma blocker) (Diagnostic Test)
single shade universal resin composite(GC solare sculpt) with chameleon effect
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.

结局指标
主要结局
shade matching
时间窗: 12 months
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
