title: Apical microleakage of primary teeth root canal filling materials by clearing technique.
abstract: The purpose of this study was to evaluate apical leakage of primary teeth root canals sealed with four different root canal filling materials by clearing technique. Dye penetration ratios of all groups were measured by light microscopy. The mean dye penetration was determined in the group of ZOE to be 0.57 mm. This ratio was 1.05 mm in the group of ZOE + glutaraldehyde (GA). In the groups of Kri I and Ca(OH)2, dye penetrations were 0.47 mm, 0.56 mm respectively. The highest apical leakage value was evaluated in the glutaraldehyde + ZOE group (p<0.05), whereas, no statistical difference was found between the other groups.
