Lack of Keratinized Gingiva
Conditions
Brief summary
A Randomized, Three Parallel Arms Clinical Trial to evaluate s the clinical impact of L-PRF vs H-PRF vs Palatal stent on the healing of the donor palatal site.
Detailed description
A Randomized, Three Parallel Arms Clinical Trial. The primary objective is to assess the clinical impact of L-PRF vs H-PRF vs Palatal stent on the healing of the donor palatal site by comparing the percentage of re-epithelization of the palatal donor site at 5, 10, 14 and 21 days using a standardized intraoral palatal photo. The secondary objective is to compare the post op discomfort between the three groups during the healing period daily for 2 weeks using the Visual Analogue Scale (VAS) and Analgesic consumption. All subjects from the University of Kentucky College of Dentistry clinics. Subjects that are coming increasing the width of keratinized tissue or for the treatment of gingival recession, and match the inclusion criteria will be told about the research and offered the opportunity to participate.
Interventions
BIOLOGICALL-PRF (Leucocyte- platelet rich fibrin)
Leucocyte-Platelet rich fibrin is a high density fibrin clot. it serves as a biological healing matrix by supporting cell migration and cytokine release, expanding the range of its potential applications greatly. Patient's own blood is centrifuged using (Intra-spin) FDA approved centrifuge on 45 degrees angle on 2700 rpm for 12 minutes.
BIOLOGICALH-PRF (Horizontal -platelet rich fibrin)
Platelet rich fibrin is a high density fibrin clot. it serves as a biological healing matrix by supporting cell migration and cytokine release, expanding the range of its potential applications greatly.Horizontally centrifuged platelet rich fibrin using (Bio-prf) centrifuge on 700 g force for 8 minutes. On a horizontal centrifugation, the cells separate much more efficiently throughout the entire membrane. This leads to better layer separation and also favors cells that are evenly distributed throughout the PRF clot.
DEVICESurgical stent
An essix surgical stent will be obtained using a high vacuum suction and used to protect the denuded donor site after suturing the wound. (Biostar® Scan/Biostar®V) will be used to make the stent.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The Clinical Impact of L-PRF, H-PRF, or the Use of a Surgical Stent on Palatal Donor Site Healing. | 5 days | The primary outcome is to asses the percentage of re-epithelization of the palatal donor site and assess primary wound healing. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| The Clinical Impact of L-PRF, H-PRF, or the Use of a Surgical Stent on Palatal Donor Site Healing. | 5 days | The secondary outcome is to compare the post-operative discomfort between the three groups during the healing period using the Visual Analogue Scale and Analgesic consumption. The visual analog scale is a validated, subjective measure for acute and chronic pain; with (0) indicates no pain and (10) indicates worst pain possible. Scores will be recorded by making a handwritten mark on a 10-cm line that represents a continuum between no pain, which is the (0) and worst pain possible, which is the (10). Also, the patient will write down his/her analgesic consumption, including the frequency and the amount used. |
