Abstract

Introduction: The goal of retrograde filling material is to create an efficient seal apically to prevent as much as possible the bacteria and its byproducts penetration from the canal of the root toward periapical area. Aim: Evaluate the impact of different root end retrograde filling materials on the degree of micro leakage apically by using methylene blue dye penetration as an indicator. Materials and Methods: Eighty permanent teeth (single root) were cut apically 3 mm at 2 different bevel angle. After that preparation of retro cavities were carried out and subsequently filled with filling materials of two types: WellROOT PT®, MTA BIOREP®. Samples placed in container filled with methylene blue stain for 1 day. Samples were prepared by dissecting using microtome and digitally viewed and photographed using digital camera connected to stereo-microscope. Micro leakage measured by utilizing Kinovea software to assess the degree of stain penetration in millimeters. The analysis of results statistically was performed by employing (Two Way ANOVA) at P<0.05. Results: Appearing from results that MTA BIOREP® groups exhibited less degree of micro leakage comparing to WellROOT PT® groups in a high statistical significant differences. Conclusion: MTA BIOREP® root end filling material was considered to be better than Well-ROOT PT® in relation to sealing ability.
