A Comparative Study of Two Different Retrograde Filling Materials with Two Different Resection Angles in Apical Surgery on the Degree of Microleakage (In Vitro Study)
Author(s): Ahmed Abdulkareem Mahmood* and Hassanien Ahmed Al-jumaily
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 b.. Read More»
