Effect of Injectable Platelet Rich Fibrin on Healing and Patient Satisfaction Following Laser Gingival Depigmentation

"* Local anesthesia was achieved using field block technique.~* A soft tissue diode surgical laser unit was used in a contact method using a flexible fiber optic hand piece with initiated tip.~* Laser irradiation parameters were adjusted as follows: Wavelength \[940 ± 10 nm\], irradiation mode \[contact continuous wave\], Power \[2 W\] and 300 μm fiber tip diameter (Jokar et al., 2019).~* The treatment was depigmentation by laser thin injection by I-PRF Post-operative instructions Instruct the patients to avoid tooth brushing on the day of surgical treatment to prevent mechanical trauma and allow re-epithelialization."
