Objective: The aim of this three years retrospective study were to present our experience with Nd: Yag laser in the therapy of chronically periapical lesions. Study design: On 56 teeth with X-ray we determined periapical radiolucency and most of them had acute symptoms characteristic for the exacerbation stadium. The teeth were opened, the contents of the canals were removed and we achieved drainage in the first session. In the second step we prepared endodontic treatment, crown-down technique for root canal instrumentation and NaOCl irrigation after each file change. The root canals were dried with paper points. The optic fiber, from the pulsed Nd YAG laser was set in each canal and laser radiation with circular slow motions from the apex to the crown was applied 3 times, each period of 5 seconds. After the treatment the root canals were obturated temporally or permanent with AH plus and gutta-percha. We made control radiograms in different periods of time after the therapy. Results: Out of the 56 tested cases, in 3 patients, after the first laser treatment, subjective symptoms were found and the patients were submitted for surgical treatment. Seventeen root canals after the sterilization with Nd: Yag laser were obturated temporally with Ca(OH)2 paste. In two cases after first laser therapy the canal system was filled with secretion and a dry working field has been achieved after 2 or 3 minutes, and then we apply a canal filling medicament. Conclusions: Nd YAG laser is efficient in the therapy of the chronically infected root canals and the periapical lesions. Тhe endodontic treatment is shorter and laser therapy calms the subjective symptoms and the clinical manifestations.
