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.
