About this study
Official title: The Effect of Two Different Approaches on Palatal Donor Site Management After De-epithelialized Graft Harvesting: Randomized Clinical Study
An epithelialized gingival graft will be harvested from the palate for the treatment of various mucogingival deformities. The donor site will be treated with either a combination of a collagen sponge, cyanoacrylate and suspending sutures or a collagen sponge, cyanoacrylate, suspending sutures and coconut oil.
Read the detailed description
After epithelialized gingival graft harvesting, intraoperatively, measurements will be taken for palatal tissue thickness, graft dimensions, working time, and primary bleeding time. Data regarding pain perception will be gauged using a visual analog scale, and the number of analgesics, secondary bleeding, epithelization level, and color match will be assessed prospectively. These outcomes will be evaluated on the first 7 days and subsequently on the 14th, 21st, and 28th days. Patient-reported outcomes will be recorded using the Oral Health Impact Profile-14 questionnaire.

What is being measured
The primary outcome is the main question the study is designed to answer.
Donor site pain perception
Patients score their daily donor site pain perception using visual analog score level by giving numbers from 0 to 10 according to the visual analog scale (0: no pain, 1: minimal pain, 10: severe pain)
Measured: everyday in first week
Secondary bleeding time
Patients will record presence or absence of secondary bleeding (presence=1 or absence=0).
Measured: during first week
Secondary outcomes (9)
Graft height
Dimensions will be measured during surgery by clinician using Michigan O probe (will be reported in mm)
Measured: during surgery
Graft width
Dimensions will be measured during surgery by clinician using Michigan O probe.(will be reported in mm)
Measured: during surgery
Graft thickness
Dimensions will be measured during surgery by clinician using Michigan O probe (will be reported in mm)
Measured: during surgery
Working time
Harvesting process will be recorded by an blinded research assistant
Measured: during surgery
Quantity of analgesics
Patients recorded the quantity of analgesics taken will be reported as quantity of pill
Measured: first week
Sensation loss
Sensation loss will be scored by the help of clinician comparing with the symmetrical side an will be recorded as no-loss, medium loss or severe loss
Measured: first week, second week , third week, fourth week.
Color match
Color match with the adjacent tissue was determined by researcher using a Visual Analog Pain Scale scale (0: absence of harmony, 10: excellent harmony)
Measured: first week, second week, third week, fourth week.
Epithelization level
Epithelization level was scored by researcher as none, partial or full epithelization by means of bubble formation after dripping hydrogen peroxide (3%) to the wound surface
Measured: first week, second week, third week, fourth week.
The Oral Health Impact Profile-14 is a questionnaire that measures how oral disorders impact a patient's quality of life.
The questionnaire has 14 items with answers rated on a 5-point Likert scale (from 1 = never to 5 = very often) to indicate a level of different problems related to oral health
Measured: first week

After epithelialized gingival graft harvesting, intraoperatively, measurements will be taken for palatal tissue thickness, graft dimensions, working time, and primary bleeding time. Data regarding pain perception will be gauged using a visual analog scale, and the number of analgesics, secondary bleeding, epithelization level, and color match will be assessed prospectively.

The record says: finished, as of the sponsor's last update on 3 Sep 2024. 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 Turkey (Türkiye). 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?
Donor site pain perception (time frame: everyday in first week). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06583226, which also lists 1 linked publication.
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 3 Sep 2024.
