The Effect of Two Different Approaches on Palatal Donor Site

NCT ID: NCT06583226

Last Updated: 2024-09-03

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: NA
• Total Enrollment: 50 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2023-10-10
• Study Completion Date: 2024-05-20

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.

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.

Study Groups

gelatin sponge + cyanoacrylate + suspending sutures

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.

Group Type: ACTIVE_COMPARATOR

Gelatin sponge stabilization with suture and cyanoacrylate

Intervention Type: DEVICE

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

gelatin sponge + cyanoacrylate + suspending sutures + coconut oil

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.
