Abstract
Mechanical properties and cure depth of visible light-cured composite resins based on six types of UDMA (IP-HEMA, IP-HPMA, XY-HPMA, MC-HPMA, UEDMA and UPDMA) monomers were investigated. Under wet conditions, the mechanical properties of the composite resins based on aliphatic UDMA (UEDMA and UPDMA) monomers were inferior to those based on the other UDMA monomers containing aromatic or cyclohexane rings in their chemical structures. The cure depth for these UDMA-based composite resins increased with increasing irradiation time. The composite resin based on the XY-HPMA monomer showed a cure depth and transmission coefficient superior to the other composite resins.
