[Microleakage detection in endodontics--a methodological review].

Recently the quality of the root canal filling can only be assessed on the basis of radiological evaluation. The Toronto study proved that the most common cause of the long-term failure of the root canal fillings is the incomplete obturation of the entire root canal system. Present methodological review makes an attempt to summarise the most important microleakage detection methods mentioning their shortcomings too. These methods are very different in their point of views, that is why their results are hardly comparable. There is a need to standardize the microleakage detection methods in order to evaluate more correctly the phenomenon existing between the root canal wall and the root canal filling materials.
