Abstract :

AIM: Comparison of the incidence of apical transportation during retreatment using 3 different intra–canal sealers. METHODOLOGY: 60 curved root canals were divided into three groups of 20 each, biomechanical preparation of the teeth was done with ProTaper rotary system and post instrumentation radiographs were taken. The teeth were obturated using ZOE sealer, AH plus and Sealapex sealers. Gutta percha was removed using ProTaper retreatment files, following which the final radiographs were taken. Post instrumentation and final radiographs were superimposed using Adobe Photoshop software. Kruskall Wallis test was used to compare the groups. RESULT: The maximum apical transportation occurred in the AH Plus group at 353µm. The apical transportation for Sealapex group was at 212µm and the minimum occurred for ZOE at 157µm. CONCLUSION: AH Plus demonstrated larger transportation compared to the other 2 sealers , which proved the increased bonding of AH–Plus sealer to the root dentin
