Microleakage between composite resin and basing materials.
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.
