Aim: The aim of this study was to evaluate the effect of hyaluronic acid gel following conventional surgical gingival depigmentation technique on the healing period and assessment of patient satisfaction. Materials and methods: 16 healthy non-smokers with hyperpigmented gingiva aged from 20-30 years were randomly assigned for conventional surgical gingival depigmentation using abrasive burs (Group I) (study); HA-gel was applied topically to the wound surface postoperatively for one week, and no application was made to (Group II) (control). Pigmentation index (DOPI) was evaluated regularly at baseline,3days,1 week,2 weeks,1 month and 3 months. While wound Healing Score and Visual analogue scale (VAS) were evaluated at 1day,3days,1 week and 2 weeks, also patient satisfaction questionnaire was done. Histological analysis was performed after 1 week.
