A comparison between a typical dressing and an absorbed dressing after surgical removal of gum pigmentation

INTERVENTION: Surgical removal of gingival pigmentation on the maxillary using surgical scallop and putting the absorbed dressing Cellulose based (reso‐pac) randomly on one side and the typical eugenol‐free dressing (Coe‐pak) on the other side. Randomisation: a coin is used to determine which side to put the absorbed dressing (Reso‐pac) and the eugenol‐free dressing (Coe‐pack) Patients were followed up for three weeks after surgery. CONDITION: Gingival melanosis ; Oral Health ; Gingival melanosis PRIMARY OUTCOME: ; 1. Pain: each day for 1 week post‐surgery using VAS (scale 0‐100); 2. Induced pain: 1 week after surgery using air abrasion of 5 seconds on every side using VAS (scale 0‐100); 3. Epithelial re‐formation: using blue toluidine in 1 week, 2 weeks, 3 weeks after surgery; 4. Healing: using Lundry Healing index Criteria (1988) 1 week, 2 weeks, 3 weeks after surgery; SECONDARY OUTCOME: Time (s) of dressing application measured using a stopwatch INCLUSION CRITERIA: 1. Healthy patient with gingival pigmentation grade 3 and 4 on the maxillary 2. Aged between 18 ‐ 40 years 3. Good oral hygiene
