| Biolase Epic X 940nm wavelength Diode laser | Device | Participants were treated with Biolase Epic X 940nm wavelength Diode laser set at a power of 1 W, fiber 400 ยต, irradiation mode: pulsed wave (P3). |
| Measure | Description | Time Frame |
|---|---|---|
| Intensity of pigmentation | Intensity of pigmentation was assessed with Dummett Oral Pigmentation Index (DOPI 1971). DOPI was scored as: Score 1: No clinical pigmentation (pink gingiva) Score 2: Mild clinical pigmentation (mild light brown color) Score 3: Moderate clinical pigmentation (medium brown or mixed pink and brown) Score 4: Heavy clinical pigmentation (deep brown or bluish black). | up to 12 weeks |
| Extension of pigmentation | Extension of pigmented area was assessed by, Hedin Melanin Index (HMI). It was scored as: Degree 1: Isolated-only 1 or 2 pigmented interdental papillae Degree 2: Numerous pigmented interdental papillae Degree 3: Short continuous ribbons Degree 4: Long continuous ribbon | up to 12 weeks |
