Comparative Evaluation of Sealing Ability of Three Different Materials as Barriers to Coronal Microleakage in Root-Filled Teeth: An Study.

Aim: To compare the sealing ability of three different materials when used as postendodontic restoration barriers to coronal microleakage in root-filled teeth.

Materials And Methods: In the present study, 60 single-rooted mandibular premolars with single canals were selected. After endodontic treatment was done with protaper files, they were divided into three groups of 20 teeth each, which were restored with Zirconomer (Group I), Hi-Dense (Group II), and Surefil composite (Group III), respectively.
