RERMOVING SMEAR LAYER DURING ENDODONTIC TREATMENT BY DIFFERENT TECHNIQUES- A INVITRO STUDY. A CLINICAL CASE- ENDODONTIC TREATMENT WITH ER: YAG LASER
a. b.
Figure 4. a. Radiograph and b. Photograph demonstrated maxillary lateral incisor tooth no # 12 with radiolucency and sinus-tract at the apical area
a. b.
Figure 5. a. LAI with Er: YAG laser. Radiation was set to 0.5 W, 50 mJ, 10 HZ for 60 seconds. b. Rubber-dam on tooth no # 12 with laser safir tip
The final obturation was accomplished at the same appointment. Approximately 2 years later, the radiograph demonstrates that radiolucency
ceased and the periapical tissues heal normally.( Fig 6) and there is no evidence of the sinus-tract.

6. Conclusion Smear-layer removal was most effective when the root canals were irrigated using Er: YAG laser at low energy with 17 % EDTA solution.
