Outcome Measures

Primary Outcomes (1)

  • Change in gingival pigmentation

    decrease melanin color of the gingiva and transform into regular pink color either by surgical; or non-surgical technique measured by The Dummett oral pigmentation (DOPI) (Dummett, 1945) for the intensity of oral pigmentation The scoring criteria as 0=Gingiva in pink color,1=Mild light brown gingival color,2=Medium gingival color or mixed (brown \&pink) gingival color and 3=Deep brown /blue-black gingival color

    measured at baseline, 1 month, 3 month and 6 months postoperative

Secondary Outcomes (4)

  • post operative pain

    After the procedures, a day of procedures and a week of procedures

  • changes in gingival pigmentation distribution

    base line ,1month,3 months and 6 months

  • Gingival bleeding

    At the time of procedures

  • wound healing

    After a day of procedures and after a 7-10 day of procedures

Study Arms (2)

surgical treatment

ACTIVE COMPARATOR

Patients with gingival hyperpigmentation of oral mucosa. For the scalpel technique, following the administration of a local anesthetic solution, a partial split thickness flap was raised with the help of blade no. 15 with the Bard Parker handle to scrape the epithelium in maxillary anterior area from canine to canine in the other side; will be surgical removal of pigmentation using the scalpel in 45 degrees to remove the superficial layer. Bleeding Will be controlled using a pressure pack with sterile gauze. Care was taken that excessive tissue was not removed thereby avoiding any bone exposure. This will be followed by careful examination of the exposed connective tissue surface, and the wound will be irrigated with saline. Bleeding will be controlled using a pressure pack, and once hemostasis is achieved, the site will be covered by a periodontal dressing for a period of one week. patients will be advised to stop eating hard, acidic, spicy, and colored foods before surgery-

Procedure: surgical treatment

non surgical with PUFA injection

EXPERIMENTAL

The hyperpigmented gingiva in the canine/1st premolar region to the contralateral comparable tooth region in the maxillary aesthetic areas will be the target area for this procedure. A local anesthesia will be used to numb the area. Using an insulin and plastic syringe (needle: 30-gauge, 8 mm length), 1-2 gram /0.1-0.2 ml of Omega-3 (PUFAs) will be injected into the gingiva at approximately the epithelial connective tissue interface until the tissue blanche, 2-3 mm apart. The insulin syringe, bevel facing upward, will be inserted into the corresponding gingival tissues. For four weeks, this dosage of omega-3 (PUFAs) will be administered once a week. Furthermore, patients will take 2 capsules. Each capsule contains 1 gram of Omega3(PUFAs) as an additional food supplement (up to 3 gram daily for the period of injection except the day of injection. the patients will receive a packet containing required number of capsules have to be taken every week.

Combination Product: non surgical with PUFA injection

You may qualify if:
