Read the detailed description
This clinical study will be carried out to compare the efficacy of ceramic soft tissue trimming bur versus the conventional surgical scraping technique in the management of gingival hyperpigmentation.
This study will be conducted to assess:
Primary objectives:
- Clinical outcome of the gingival depigmentation procedure.
- Assessment of postoperative pain using the visual analogue scale.
- Patients' satisfaction will be assessed using the patient satisfaction questionnaire (short-form, PSQ-18) and the global aesthetic improvement scale.
Secondary objectives:
- Operating time.
- Wound healing.
- Conditions
- Hyperpigmentation
- Being tested
- depigmentation

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
depigmentationProcedure or surgery
gingival depigmentation
| Study group | Role | What they receive |
|---|---|---|
| ceramic soft tissue bur | Experimental | Eight dental arches were treated by ceramic soft tissue bur Receives: Procedure: depigmentation |
| scalpel | Active comparator | Eight dental arches were treated by conventional scalpel technique Receives: Procedure: depigmentation |
What is being measured
The primary outcome is the main question the study is designed to answer.
clinical outcomes of depigmentation procedure
dummet oral pigmentation index ( DOPI): 1= pink no pigmentation (better) 4= deep brown (worse) Melanin index (MI):1= isolated pigment (better), 4= long continous ribbon (worse). reported by visual inspection.
Measured: 3 month postoperative
patient satisfaction
global aesthetic improvement scale 5 point likert scale 1= excellent improvement 5= worsened. patient reported outcome.
a score from 1 to 5, 1 being better
Measured: 3 months postoperative
Percieved pain
postoperative pain will be assessed using visual analoque scale (VAS): 1= being the least pain and 10= being the most severe
Measured: 7 days
Secondary outcomes (2)
operating time
time taken from the beginning of the procedure to its end by stopwatch
Measured: during surgery
Wound healing
- Complete reepithelialization
- Incomplete reepithelialization
- ulcer
- tissue defect or necrosis Dummet 1966
Measured: 7 days postoperative

Questions about this trial
What is this clinical trial studying?
A study testing depigmentation in people with Hyperpigmentation, run by Ain Shams University at 1 site in Egypt.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
clinical outcomes of depigmentation procedure (time frame: 3 month postoperative). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Sep 2023; AzTrials last refreshed its copy on 7 Nov 2026.
