Plain English summary of protocol

Background and study aims
Gum pigmentation (gingival pigmentation) is caused by melanin and melanin is a natural substance in the body that is found in freckles, sun spots, age spots. Some people have an overproduction of melanin in their gums. Discoloration may also be caused by long term use of certain medications.
Proper healing is a must for a successful periodontal surgery. Many new dressings are made and tested to reach a perfect dressing to insure complete and fast wound healing. The absorbed (cellulose-based) dressing (Reso-Pac) is the newest dressing. In this study, it is compared with the traditional dressing (Coe-Pack) in healing wounds.

Who can participate?
Healthy patients aged 18 – 40 years who have gingival pigmentation.

What does the study involve?
After surgical removal of gingival pigmentation, participants will receive two different types of wound dressing, one on each side of the mouth. Healing will be assessed for three weeks after the surgery.

What are the possible benefits and risks of participating?
The benefit is the potential for faster healing. The risks will be to have an allergic reaction towards the new dressing

Where is the study run from?
Damascus University Department of Periodontology (Syria)

When is the study starting and how long is it expected to run for?
November 2019 to January 2021.

Scientific titleA comparison between eugenol-free dressing (Coe-Pack) and absorbed dressing (Reso-Pac) after surgical removal of gingival pigmentation (spilt mouth study)
Study objectivesThe new cellulose-based dressing (Reso-Pac) will be more successful in healing wounds compared to the traditional dressing (Coe-Pack)
Ethics approval(s)Approved 18/6/2019, Damascus University Ethics Board (Mazzeh Highway, Damascus, Syria; +963 1133923486; sr.srd@damasuniv.edu.sy), ref: co2733
Health condition(s) or problem(s) studiedGingival melanosis
InterventionSurgical 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.
Intervention typeProcedure/Surgery
Primary outcome measure1. 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 measuresTime (s) of dressing application measured using a stopwatch
Overall study start date20/04/2019
Completion date15/01/2021
