Outcome Measures

Primary Outcomes (17)

  • pain assessing

    visual analogue scale (VAS) method - a questionnaire will be given to the patients in which their responses for Visual Analog Score that ranges from 1-10 values and highest values indicate the worst outcomes.

    1st day post operatively.

  • pain assessing

    visual analogue scale (VAS) method - a questionnaire will be given to the patients in which their responses for Visual Analog Score that ranges from 1-10 values and highest values indicate the worst outcomes.

    3rd day post operatively.

  • pain assessing

    visual analogue scale (VAS) method - a questionnaire will be given to the patients in which their responses for Visual Analog Score that ranges from 1-10 values and highest values indicate the worst outcomes.

    7th day post operatively.

  • pain assessing

    visual analogue scale (VAS) method - a questionnaire will be given to the patients in which their responses for Visual Analog Score that ranges from 1-10 values and highest values indicate the worst outcomes.

    14th day post operatively.

  • pain assessing

    visual analogue scale (VAS) method - a questionnaire will be given to the patients in which their responses for Visual Analog Score that ranges from 1-10 values and highest values indicate the worst outcomes.

    1 month post operatively.

  • Healing of gingiva

    hick healing index- score ranges from 0 to 4, higher values indicate the worst outcomes.

    1st day post operatively

  • Healing of gingiva

    hick healing index- score ranges from 0 to 4, higher values indicate the worst outcomes.

    3rd day post operatively

  • Healing of gingiva

    hick healing index- score ranges from 0 to 4, higher values indicate the worst outcomes.

    7th day post operatively

    1 month post operatively

  • epithelial healing

    3% of hydrogen peroxide is applied on the operated area. no bubble- complete epithelization, bubble formation- incomplete epithelization.

    7th day post operatively

  • epithelial healing

    3% of hydrogen peroxide is applied on the operated area. no bubble- complete epithelization, bubble formation- incomplete epithelization.

    14th day post operatively

  • epithelial healing

    1 month post operatively

  • need of analgesics

    on scale of 0-9, where higher variable represents more pain

    1st day post operatively

  • need of analgesics

    on scale of 0-9, where higher variable represents more pain

    2nd day post operatively

  • need of analgesics

    on scale of 0-9, where higher variable represents more pain

    3rd day post operatively

  • rise in temperature

    FLUKETM 59 Mini (IR) infrared thermometer is used to measure temperature at surgical site, more rise in temperature indicate more carbanoization.

Group 300µm in continous contact mode

EXPERIMENTAL

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 , 300 µm fibre length will be used in continuous contact mode at a power setting of 1.5 to 3 W. • Simultaneously, increase in temperature on site will be recorded using FLUKETM 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.

Procedure: 300 µm fibre length will be used in continuous mode
