The stiffness of the composite makes dispensing from the syringe somewhat difficult, but the composite is easy to control during placement, is not sensitive to ambient light, and adapts well to cavity preparations. The material does not stick to the placement instruments and can be contoured to the desired shape before curing. The shade match after curing is consistent with the selected Vita shade. The composite was highly rated for blending with tooth structure, radiopacity, and ease of finishing. Prime-Dent Nano-Hybrid Light Cure Composite can be finished and polished to a high luster with conventional techniques.
