This study investigated the microleakage between a composite resin restorative material and six basing materials. Cavities were prepared in polymerized composite resin samples and “restored” with Cavitec, Life, Ketac‐Bond, BaseLine, Cavalite, and VLC Dycal. The samples were thermocycled and immersed in 0.05 percent crystal violet solution for 2 hours, then embedded in clear casting resin, sectioned and examined with an optical microscope. Our results indicated that Cavalite and VLC Dycal allowed no dye penetration. Cavitec and Life had a moderate degree of dye penetration and Ketac‐Bond and BaseLine had a relatively high degree of penetration.
