case_images: The interstitial-intralesional laser technique.. A. The optical fiber was inserted into the lesion, beginning at the base of the lesion and then progressing to the top. The optical fiber was placed tangentially to the tooth and root surface.. B. After a single treatment with interstitial-intralesional laser therapy on four areas.

case_images: The remission of the pyogenic granuloma was observed, as shown in Figure 6A, B and C.
case_images: The LANAP procedure.. A. The 980 nm diode laser was used for dilating the gingival sulcus.. B. Scaling and root planning with hand instruments.. C. The 980 nm diode laser was used for ablating the long junctional epithelium and granulation tissue in the gingival sulcus.. D. Toluidine blue was injected as a photosensitizer into the gingival sulcus.. E. The gingival sulcus was irradiated with a 635 nm diode laser via a 200-micron flexible tip to initiate photosensitizer.
