Abstract
Objectives: In an attempt to increase the successful rate of endodontic surgical procedures this study proposes the use of an association of three lasers in apicectomy: Er:YAG laser, (wavelength 2.94 μm pulse mode), Nd:YAG laser (wavelength 1.064 μm, pulse mode), and Ga-Al-As laser, (wavelength of 790 nm, continuous wave). Background Data: Previous studies have shown the low success rate of apicectomy by conventional methods due to the presence of remaining bacteria in the surgical site. Methods: The Er:YAG laser was used to perform osteotomy and root resection without vibration, discomfort, less contamination of the surgical site, and no smear-layer on the dentine surface. The Nd:YAG laser irradiation through a fiber performed sealing of the dentinal tubules and bacterial reduction of the cavity bone. In addition, the improvement of healing and better post-operative achieved with the Ga-Al-As laser encourages the use of those lasers in periapical surgeries.Results: Three years follow-up examination of the clinical case showed radiographically significant decrease of the radiolucent periapical area and no clinical signs and symptoms. Conclusion: The outcome of this clinical case indicates that the use of those lasers could be considered an alternative, suitable, and useful method to perform an apicectomy.
