Background: The solubility of root end filling materials is strongly affected by the environment they are in contact
with. The aim of this study is to compare the solubility of CEM cement in two neutral and acidic environments.
Materials and Methods: 40 metal rings filled with CEM cement were prepared and were randomly divided into two groups. Samples
in groups 1 and 2 were placed in artificial interstitial fluid with pH = 7.4 and pH = 4.4 and then were transferred into bottles containing
distilled water with pH = 7.4 and pH = 4.4. Solubility of CEM cement samples were calculated in two time periods. Data were
analyzed using independent t-test.
Results: The results of this study showed the level of solubility in acidic group on both days 7 and 28 was more than the neutral
group, which was statistically significant (P = 0.001).
Conclusion: The solubility of CEM cement in the neutral and acidic environment increases with time. The more acidic the environment,
the greater the dissolution.
