Conventional, light-cured flowable composite that is being marketed for basically all types of restorations including Class I and II and as a luting cement for
veneers. It has the moniker Universal since it only comes in two shades: U which stands for Universal and UD which is Universal Dark. Regular Universal is designed for all Class I and II applications and for Class iii, iv, and V when you are trying match the following shades: B1, A1, B2, D2, A2, C1, C2, D4, A3, and D3. On the other hand, UD will presumably match B3, A3.5, B4, C3, A4, and C3.
