Abstract Micro-leakage testing has been used to determine the possible clinicalperformance of a restorative material. A large number of different techniques have been developed for the investigation of micro-leakage. Many micro-leakage testing materials have been developed andperformed through the years. There has been no agreement as to which testing methodology would give the most accurate results. Attempts have been made to simulate the oral conditions and to give a more quantitative representation of micro leakage. The different micro leakage testing methodologies are presented in this paper.
