Berk, G./Ulucam, S./Berk, N.
Purpose: To ducument a clinical and radiographical follow-up after root canal treatment of teeth with periapical lesions using an Er,Cr:YSGG hydrokinetic system laser (Waterlase).
Materials and methods: YSGG laser applied at 20 Hz , 5.0 to 1.0 W with 30% to 90% air-water spray was used for complete root canal therapy in 2 patients bearing 3 teeth with periapical lesions. Radiographs were taken and percussion was tested after the filling procedure, at the end of the first week, and 3 months later.
Results: According to the Coba et al classification, 3 of the teeth were nonsymptomatic to percussion in both controls; radiography showed that lesions healed completely.
Conclusion: These results pointed out that YSGG laser can be used for complete root canal therapy both for incisors and molars, and healing fast and good.
