The use of the erbium yttrium aluminium garnet (2,940 nm) in a laser-assisted apicectomy procedure.

If conventional endodontic treatment is not possible or not successful, apical endodontic surgery may be indicated. New techniques, materials and technologies have been used to increase the already high success rate of root canal treatment. The purpose of this article is to describe the use of the Erbium:YAG (2,940 nm) laser in treatment of apicectomy as a central tool, with the advantages of enhanced patient comfort, better bactericidal and decontamination effects.
