Trial outcomes

Primary outcomes

1

Degree of gingival pigmentation by Takashi index (Hanioka et al., 2005)

Degree of gingival pigmentation 0: no pigmentation 1. solitary unit (s) of pigmentation in papillary gingiva without extension between neighboring solitary units 2. formation of continuous ribbon extending from neighboring solitary units)

Time frame
baseline: before surgery/injection (day1), after 1 mon ,3 mon ,6 mon and 9 month
2

Degree of gingival pigmentation by Gingival pigmentation index (Kumar et al., 2013)

Score 0: absence Score 1: spots of brown to black Score 2: brown to black patches but not diffuse Score 3: diffuse brown to black pigmentation

Time frame
The color assessment will be evaluated in the daylight and by examining the regular digital photographs which will be taken pre-operative (day of the procedure / day 1), and post-operatively after 1 month and 9 months.

Secondary outcomes

1

Pain score

VAS scores pain will be divided into ten numerical parts consisting of one cm each on a horizontal line with two endpoints (left and right), with "0" representing "no pain" to "10" representing "severe pain."

Time frame
visual analogue scale (VAS) after the surgery/injection (day 1) till 10 days after (day 10 after the surgery/injection)
2

Itching

A vertical scale for wound itching was measured with a scale with five scores: no itching (0) mild itching (1point) moderate itching (2 points) severe itching (3 points) extremely severe (4 points)

Time frame
visual analogue scale (VAS) after the surgery/injection (day 1) till 10 days after (day 10 after the surgery/injection)
3

Patient satisfaction

using a 5- graded self-assessment analysis (Huh et al. 2003). excellent (grade 4: improved over 75%) good (grade 3: improved 50e75%) moderate (grade 2: improved 25e50%) fair (grade 1: improved less than 25%) no change or worse (grade 0: not improved or darkened)

Time frame
At the end of the follow up period ( 9 months)
