Paper Abstract

To perform this study, 40 extracted single rooted human teeth were used to compare dye leakage between apicoectomy following amalgam retrofill and apicoectomy using CO2 laser irradiation. All the 40 teeth were endodontically treated and than were separate in two groups of 20 teeth each. A bur was used to ressect the apexes of the sample of group I followed by silver amalgam retrofill. the 20 teeth of group II had their apexes ressected with a Carbon Dioxide laser beam. All the samples were submerged into a methylene blue dye solution, washed, longitudinally sectioned and graded upon the level of leakage by two separate examiners. The result showed a perfect concordance between both examiners and also, a non significant difference on the level of leakage in the two groups.
