Electrical and dye leakage comparison of three root-end restorative materials.

Objective: The purpose of this study was to assess three modern root-end restorative materials with electrical and dye leakage tests.

Method And Materials: Thirty-three human canine teeth were prepared and filled with gutta-percha and sealer. Stainless steel rods were inserted into the root canals as anodes, and the teeth were varnished.
