Abstract: Bulk-fill composite resin is gradually applied to dental treatment now. Some studies have found that it not only has the advantage of convenient operation, but also has good clinical effect. As an important index of resin curing degree, the monomer conversion is an important factor that determines the mechanical and biological properties of composite resin. Cuspal deflection and marginal microleakage are caused by the polymerization shrinkage stress resulting from the shrinkage of composite resin, and it has certain influence on the durability of filling body and marginal sealing. It can be regarded as a common indicator of the clinical effect of composite resin. This paper mainly reviews the clinical effect and mechanism of bulk-fill composite resin through the monomer conversion, cuspal deflection and marginal microleakage.

Key words: bulk-fill composite resin, monomer conversion, cuspal deflection, marginal microleakage
