Ex-vivo Sealing Ability of Different Thicknesses of White and Gray Angelus MTA as an Intra-orifice Barrier in Endodontically Treated Teeth

Abstract

It is important for the clinician to be aware regarding the necessary thickness of materials used as intra-orifice coronal barriers to prevent microleakage. The purpose of this in vitro study was to compare coronal microleakage of three different thicknesses of white and gray Angelus mineral trioxide aggregate (WAMTA, GAMTA). Conclusion: Coronal microleakage of 2-mm thickness of WAMTA and GAMTA had no statistically significant difference with 3-mm and 4-mm thicknesses of the materials.
