NCT05283668

Brief Summary

The objectives of the present study are to:

  1. 1.Evaluate the effect of I-PRF injection following laser gingival depigmentation technique on the healing period as a primary objective.
  2. 2.Assess patient satisfaction following the procedure in terms of pain and esthetic outcome as a secondary objective.

Outcome Measures

Primary Outcomes (2)

  • Dummet oral pigmentation index

    the degree of gingival pigmentation will be scored as: 0 = pink tissue \[no clinical pigmentation\]; 1 = mild light brown tissue \[mild clinical pigmentation\]; 2 = medium brown or mixed brown and pink tissue \[moderate clinical pigmentation\]; or 3 = deep brown/ blue-black tissue \[heavy clinical pigmentation\]

    1 month

  • Clinical wound healing

    scored as follows: 1\) Complete reepithelialization, 2) Incomplete reepithelialization, 3) ulcer and 4) tissue defect or necrosis

    1 week

Secondary Outcomes (3)

  • Satisfaction questionnaire

    1month

  • Visual analogue scale (VAS) score for pain assessment

    1month

  • Histological assessment

    1 week

Study Arms (2)

(LASER WITH I-PRF)

EXPERIMENTAL

Eight sites that were treated with laser method for gingival depigmentation, followed by intra-mucosal field injection of I-PRF

Biological: i-PRFProcedure: Diode Laser

(LASER WITHOUT I-PRF)

ACTIVE COMPARATOR

Eight sites that were treated with laser technique for gingival depigmentation only

Procedure: Diode Laser

Interventions

i-PRFBIOLOGICAL

* 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.
