The Effect of Two Different Approaches on Palatal Donor Site

NCT06583226 | Completed

• 1 other identifier: 636
• Study Type: interventional
• Target: 50
• Locations: 1 country
• Sites: 1

Brief Summary

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.

Conditions

Wound Heal

Keywords

coconut oil; wound healing; palatal graft harvesting

Outcome Measures

Primary Outcomes (2)

• 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)

  everyday in first week

• Secondary bleeding time

  Patients will record presence or absence of secondary bleeding (presence=1 or absence=0).

  during first week

Secondary Outcomes (9)

• Graft height

  during surgery

• Graft width

  during surgery

• Graft thickness

  during surgery

• Working time

  during surgery

• Quantity of analgesics

  first week

Study Arms (2)

gelatin sponge + cyanoacrylate + suspending sutures

ACTIVE COMPARATOR

After administration of local anesthesia (2% articaine hydrochloride with epinephrine 1:100,000), palatal thickness will be measured by perpendicularly inserting a Michigan-O periodontal probe from the corners of the rectangular donor area. Epithelialized gingival graft will be harvested. After a rectangular-shaped initial incision, a graft with 1-1.5 mm thickness will be harvested approximately 1.5 to 3 mm away from the gingival margins of the upper teeth. The donor site will be closed with a gelatin sponge + cyanoacrylate + suspending sutures.

Device: Gelatin sponge stabilization with suture and cyanoacrylate

gelatin sponge + cyanoacrylate + suspending sutures + coconut oil

ACTIVE COMPARATOR

After local anesthesia (2% articaine hydrochloride with epinephrine 1:100,000) administration, palatal thickness will be measured by perpendicularly inserting a Michigan-O periodontal probe from the corners of the rectangular donor area and the mean value will be recorded as palatal tissue thickness. The epithelialized gingival graft will be harvested using 15 knives. After a rectangular-shaped initial incision, a graft with 1-1.5 mm thickness will be harvested approximately 1.5 to 3 mm away from the gingival margins of the upper teeth. The donor site will be closed with a gelatin sponge, cyanoacrylate suspending sutures and coconut oil.

Procedure: Gelatin sponge stabilization with suture and cyanoacrylate and coconut oil application

Interventions

Gelatin sponge stabilization with suture and cyanoacrylate DEVICE

The donor site will be closed both with gelatin sponge +Cyanoacrylate (Spongostan®, Ethicon, USA)+ supporting sutures (control group)

gelatin sponge + cyanoacrylate + suspending sutures

Gelatin sponge stabilization with suture and cyanoacrylate and coconut oil application PROCEDURE

Seconder The donor site will be closed both with gelatin sponge +Cyanoacrylate (Spongostan®, USA) and coconut oil (test group)

gelatin sponge + cyanoacrylate + suspending sutures + coconut oil
