However, the use of novel methods and materials in periapical surgery has increased the success rates of treatment. The objective of this study was to assess the effects of mineral trioxide aggregate (MTA) retrofilling and apical sealing with Nd:YAG laser (at 10\u2009Hz, 150\u2009mJ, 1.5 W, in 60\u2009sec pulses) as adjuncts to apicoectomy.\n                    <jats:bold>\n                      <jats:italic toggle=\"yes\">Methods:<\/jats:italic>\n                    <\/jats:bold>\n                    Perpendicular root end resection was performed with diamond-coated burs on 40 canine teeth previously subjected to endodontic treatment.
