ABSTRACT

Dental composite resin is a kind of material which has been widely used in dental restoration. It was found that the marginal adaptation of the composite resin was slightly misfit and microleakage was easily formed. The harms of microleakage of composite resin was discussed in this paper. The effects of resin matrix and inorganic filler, initiating system, illumination, repair technique and surface treatment on the polymerization shrinkage of composite resin were also analyzed. The paper also discusses the effective measures to reduce micro-leakage of resin, and offers theoretical basis for the clinical application and development of composite resin.
