Abstract EN
Background : apicoectomy and retrograde filling is indicated when conventional endodontic treatment is impossible or failed to achieve apical seal.
The aim of this study was to evaluate the effect of ER: YAG laser on apical micro leakage.
Materials and Methods : Sixty extracted single-rooted teeth were used in this study.
The roots were divided into six groups.
Group 1: apicoectomy by fissure bur, and apical cavities prepared by round bur, then cavities were filled with MTA.
Group 2: the roots preparations and fillings were the same as group 1, then the apical areas were treated by Er : YAG Laser.
Group 3 : apicoectomy by fissure bur, and apical cavities prepared by ultrasound retrotip and cavities were filled with MTA.
Group 4 : the roots preparations and fillings were the same as group 3, then the apical areas were treated by Er:YAG Laser.
Group 5: the roots obturation with gutta percha, then the apices were resected using Er : YAG Laser.
Group 6 : the roots apices were resected with Er : YAG Laser, then the canals were obturates with gutta percha.
Apical microleakage was measured by methylene blue dye penetration technique.
Results : significant difference between the groups.
Group 1 shows the best apical seal, while group 5 shows the worse apical sealing ability.
Conclusion : apicoectomy by bur is better than apicoectomy by laser, and apical cavity prepared by bur is better than prepared by US.
The use of ER : YAG laser in apicoectomy is preferred to be done before obturation of the root canal with gutta percha.
