This study was conducted to investigate properties of current composite veneering materials polymerized with various laboratory photo-curing units for the purpose of evaluating the curing performance of the light sources. A microfilled composite material designed for prosthetic veneer (Dentacolor) was polymerized with nine photo-curing units, and the curing depth obtained with each unit was compared. The curing depth of the material was determined using the method described by the International Organization for Standardization (ISO 4049). In addition, six other properties (Knoop hardness, compressive strength, flexural strength, flexural modulus, water absorption, and solubility) of three composite veneering materials (Cesead II, Dentacolor, and Solidex) polymerized with two different units were also determined. The respective light sources of the units were a xenon (Dentacolor XS) and a metal halide (Hyper L II) lamp, and the composite materials were exposed with the units for 90 s on each side. The results were as follows:<BR>1. Among the nine photo-curing units, the metal halide unit consistently exhibited the greatest curing depth.<BR>2. Knoop hardness, flexural modulus, and solubility were influenced by the type of the photo-curing unit.<BR>3.All the composite materials exposed with the metal halide unit demonstrated significantly lower solubility than those exposed with the xenon unit.
