This study investigated the microleakage between glass‐ionomer cement and Silux or Herculite with and without Scotchbond 2. Cavities were prepared in polymerized composite resin samples and “restored” with a glass ionomer cement with and without Scotchbond 2. The samples were thermocycled and immersed in 0.05% crystal violet solution for 2 hours, then embedded in clear casting resin, sectioned, and examined with an optical microscope. The results indicated that a high degree of dye penetration was found in samples of GC and Silux, and GC and Herculite without Scotchbond 2. The use of Scotchbond 2 significantly reduced the degree of dye penetration, but did not completely eliminate dye penetration.
