The Use of Er:YAG, Nd:YAG and Ga-Al-As Lasers in Periapical Surgery: A 3-year Clinical Study

S Gouw-Soares et al. J Clin Laser Med Surg.

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 microm pulse mode), Nd:YAG laser (wavelength 1.064 microm, 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.
