Study: NCT04217434

Intervention type: PROCEDURE
Group type: EXPERIMENTAL
Intervention: 400 µm fibre length will be used in continuous contact mode
Description: Diode LASER (A.R.C Fox, Germany, UK) with wavelength of 810nm is selected for the procedure. Before applying the LASER, operating staff and the patient will wear special LASER protective eye glasses.~Local infiltration is administered with Lignox®\[ 2% lignocaine in 1:80000 adrenaline\].~LASER tip will be used in contact mode on pigmented gingiva in short light paint brush strokes using 400 µm fibre length will be used in continuous contact mode at a power setting of 1.5 - 3W. Simultaneously, increase in temperature on site will be recorded using FLUKE 59 Mini (IR) infrared thermometer in non contact mode. Water spray will be used to keep the area moist. Same procedure will be repeated till no pigments remain.Post operative instructions will be given.

Group type: EXPERIMENTAL
Intervention: 400 µm fibre length will be used in pulsed contact mode
