Dental composite resin is a tooth-colored restorative material used to replace a decayed portion of tooth structure. Its esthetic appearance is the main advantage over the conventional dental amalgam.
What are the different types of composite resin in dentistry?
As with other composite materials, a dental composite typically consists of a resin-based oligomer matrix, such as a bisphenol A-glycidyl methacrylate (BISGMA), urethane dimethacrylate (UDMA) or semi-crystalline polyceram (PEX), and an inorganic filler such as silicon dioxide (silica).
What is resin used for in dentistry?

What is the best way to take a patient’s color shade?
It’s best to select the shade at the beginning of the patient’s appointment, before treatment begins.
