“Stereomicroscopic dye penetration study evaluating the sealing ability of three different furcation repair materials” - An in vitro study

Abstract

Perforations have been found to be one of the most eminent cause of endodontic failures. Perforations of the root walls may be induced by iatrogenic causes, resorptive processes, or caries. The prognosis of endodontically treated teeth with perforations depends on factors such as the time lapsed before obturating the defect,the location of the perforation, adequacy of the perforation seal, size of the perforation and the material used to seal the perforation. Numerous materials have been recommended for the repair of perforations including gutta-percha, amalgam, indium foil, calcium hydroxide, tricalcium phosphate, cavit, zinc oxide eugenol, hydroxyapatite and plaster of paris. The objective of the present study is to evaluate the sealing ability of MTA when used as a furcation repair material and to compare its sealing ability with Light cured GIC and Cavit
