Microleakage is defined as the passage of ions, bacteria or bacterial toxins between the tooth restoration interface. The different causes for occurrence of microleakage are, poor adaptation of restorative materials, its contraction during setting, non-adherence to tooth structure, deformation under loads or temperature induced volume changes. To avoid this microleakage becoming a complication we should first be able to detect the materials that tend to leak. This article presents the methods to detect microleakage in invitro and invivo conditions.
