【 摘 要 】

We studied the depth of cure obtained in flowable composite resins when illuminated through ceramic blocks of different composition and different thicknesses. The flowable composite resin was deposited in forming metal cylinders of 4mm of high and 6mm of diameter, brought to volume and then illuminated for 60 sec interposing the different ceramics between light and resin. A LED lamp was used to illuminate the material. Some of the groups exhibited significant differences among them depending on the thickness of the ceramic and its type. Flowable resin may polymerize through ceramics of different thicknesses and could be used for the cementation of ceramic restorations.
