Hyderabad. An evaluation of two resin systems for restoration of abraded areas. It depends on: resin shade, light intensity, box deep, resin thickness, curing through tooth structure, composite filling. Most of the commercial products are dual-cured, combining chemical and light-activation mechanisms. Dental composite resins (better referred to as "resin-based composites" or simply "filled resins") are dental cements made of synthetic resins.Synthetic resins evolved as restorative materials since they were insoluble, of good tooth-like appearance, insensitive to dehydration, easy to … according to botanical origin, e.g. Macro-filled 8-12 µm 75-80 wt% 2. Resin luting agents are distinctive because a polymer matrix forms to fill and seal the space between the tooth and the restoration as opposed to regular cements, which combine a powder and liquid to form a hydrogel.
