PHOTODYNAMIC THERAPY
Procedure/SurgeryRespective photosensitive dye solution is applied on to the surgical site, including all the root surfaces. Vacuum suction is used to remove the excess dye from the site and to prevent ingestion of the dye solution The dye is activated with 810nm diode laser with continuous wave frequency and power of 0.3 W with 400 µm fiber tip for 20 seconds/spot. After this, the area is irrigated with saline.
