Review: Resin Composite Filling

Abstract

The leading cause of oral pain and tooth loss is from caries and their treatment include restoration using amalgam, resin, porcelain and gold, endodontic therapy and extraction. Resin composite restorations have grown popular over the last half a century because it can take shades more similar to enamel. Here, we discuss the history and use of resin, comparison between amalgam and resin, clinical procedures involved and finishing and polishing techniques for resin restoration. Although resin composite has aesthetic advantages over amalgam, one of the major disadvantage include polymerization shrinkage and future research is needed on reaction kinetics and viscoelastic behaviour to minimize shrinkage stress.

Development of an oxirane/acrylate interpenetrating polymer network (IPN) resin system

“…Modern methacrylate-based resins can have volumetric shrinkages of ~5% unfilled and 2–3% when filled [27–29]. Oxiranes should aid in stress relaxation over time via its ring-opening mechanism [20, 30].…”

Effects of artificial accelerated aging on the optical properties of resin composites

“…However, some of these components may degrade over time, affecting the resin composite's optical characteristics and durability, and could compromise the esthetic outcome obtained initially. Color stability is a crucial factor for an aesthetic restorative material, and visible color change is a major cause of replacing restorations in anterior teeth (CHAN et al, 2010).…”

Inverse Gas Chromatographic Examination of Polymer Composites

“…In many cases a coupling agent to improve their adhesion is required. Polymerization initiators allow hardening by blue light photopolymerization [41][42][43][44][45][46][47]. Glassionomer cements are composed of polycarboxylic acid, fluoroaluminosilicate glass, water, and tartaric acid.…”
