Effectiveness of erbium laser in the treatment of apical periodontitis: a clinical observation

Abstract

This article presents a clinical case of therapeutic treatment of a 36-year-old patient with chronic granulomatous periodontitis of 2.4 teeth (K04.5). The patient provided informed consent for treatment, participation in a scientific study, and publication of personal medical information. Repeated endodontic treatment was performed, including unsealing and root canal shaping with K- and H-files and the ProTaper system. Bidistillate was used as an irrigant. For root canal disinfection, Er,Cr:YSGG laser with a wavelength of 2780 nm at a power of 1.5 W, frequency of 50 Hz, water/air of 25/35, pulse of 20, and tips of 200 μm was used. Clinical follow-up was performed after 7 days and 6 and 12 months, and radiologic follow-up was conducted after 6 and 12 months based on cone-beam computed tomography and periapical COPI index data. At 12-month follow-up, complete recovery of periapical tissues was noted. The long-term results confirm the effectiveness of repeated endodontic treatment.
