Effect of Oxidant Gel and Anti-oxidant Gel on Wound Healing After Gingival Depigmentation

Study Overview
=================
Brief Summary
-----------------
To evaluate effect of Oxidant (Oxygen Releasing Oral Gel) with Coe-Pak versus Anti-oxidant (Nano-emulsion complex propolis and vitamin C gel) with Coe-Pak on wound healing, pain, patient satisfaction after gingival depigmentation

Detailed Description
-----------------
Gingival depigmentation is considered a periodontal plastic surgery, in which gingival hyperpigmentation is eliminated. The scalpel surgical method is one of the most cost-effective methods, easiest and does not need broad equipment. However, scalpel surgery leads to bleeding during and after surgery, and the surgical area has to be covered with periodontal dressing for 7-10 days. Periodontal dressings are used around the necks of the teeth and surrounding tissue to cover the wound. Non-eugenol dressings are now the most commonly used periodontal dressings include Coe-Pak, Cross Pack, Peripac, Septopack, PerioCare, Perio Putty and Periogenix. Anti-oxidant gel (Nano-emulsion complex propolis and vitamin C - NBF GINGIVAL GEL®) is a high efficiency nano bio fusion gel containing propolis, nano vitamin C, E and herb extract. Anti-oxidant power of nano Vitamin C (NBF GINGIVAL GEL®) is ten times more effective in hundred times smaller amounts, than Vitamin C by itself. Vitamin C collaboratives with Vitamin E and preserves cell membranes integrity. Propolis has antioxidant effect due to its radical scavenging ability, which was more efficient than antioxidant effect of vitamin C. it also enhances synthesis of collagen due to the presence of iron and zinc elements. it has proven to increase healing of epithelial tissues. The presence of oxygen in Oxygen Releasing Oral Gel (blue®m gel) enhances cellular metabolism, collagen synthesis, antibacterial activity, angiogenesis, revascularization, and the release of growth factors, it also helps keratinized tissue formation and has antimicrobial effects.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| wound healing | Assessment of healing using the healing index scale by Landry with scale starting from (1 for very poor healing and 5 excellent healing).Postoperatively clinical photographs will be taken. | Change in healing from baseline up to 4 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Post-operative Pain Assessment | pain score will be measured at 1st week . Visual Analogue Scale (VAS) will be used to evaluate pain with score starting from 0 (minimal pain ) to 10 ( maximum pain). Questionnaire | 7 days | 
| Post-operative Pain Assessment | pain score will be measured at 2nd week. Visual Analogue Scale (VAS) will be used to evaluate pain with score starting from 0 (minimal pain ) to 10 ( maximum pain) . Questionnaire | 14 days | 
| Patient Satisfaction | Questionnaire (yes/no) | 30 days |
