Comparison of Conventional Free Gingival Grafts With Partially De-epithelized Free Gingival Grafts

Study Overview
=================
Brief Summary
-----------------
In this study, the conventional SDG method applied to increase the adherent gingival band and partial de-epithelialized SDG methods were evaluated in terms of aesthetics and color compatibility of the recipient area with adjacent tissues. This study is a controlled double-blind clinical trial randomized by split-mouth, envelope method.Clinical parameters and aesthetic harmony were compared at postoperative 1st, 3rd and 6th months after surgical procedures.Color harmony evaluation was made in 2 different ways, both by photo analysis of a blind researcher using computer software and by visual evaluation of the same blind researcher.

Detailed Description
-----------------
The primary aim of this split mouth randomized controlled clinical trial is to compare the partial de-epithelialized free gingival grafting technique with the conventional free gingival grafting technique from an aesthetic point of view. The secondary aim of the study is to evaluate both techniques in terms of periodontal clinical parameters. This study is a controlled double-blind clinical trial randomized by split-mouth, envelope method. Fifteen patients with attached gingiva width ≤2 mm in the lower jaw bilateral canine and premolar regions were included in the study. De-epithelialized free gingival grafts were applied to the region determined by envelope randomization, and conventional free gingival grafts were applied to the other region. The areas of the patients with insufficient attached gingiva were photographed before the operation, post-op 1st, 3rd, and 6th months, and visual aesthetic evaluations were made with photo analyzes. Clinical parameters such as keratinized gingival width, probing pocket depth, and recession depths were recorded at baseline and at 6 months. Results were represented as mean ± standard deviation and median, and a p value of <0,05 was considered statistically significant.

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: control group(conventional free gingival graft)<br>Conventional free gingival grafts are applied to the areas of the patients determined by randomization as suggested by Sullivan and Atkins. | Procedure: Comparison of conventional free gingival graft versus partial free gingival graft<br>* Conventional free gingival graft was applied to the area of the patient with attached gingival insufficiency determined by randomization. Clinical and aesthetic comparisons were made in the postoperative 1st, 3rd and 6th months.<br>|
| Experimental: test group(Partially de-epithelialized free gingival graft)<br>Partial free gingival graft is applied to the areas of the patients determined by randomization. Unlike the control group, the epithelium on the graft was partially epithelialized. | Procedure: Comparison of conventional free gingival graft versus partial free gingival graft<br>* Partially de-epithelialized free gingival graft was applied to the other region of the patient with attached gingival insufficiency determined by randomization.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| aesthetic evaluation of both surgical methods | Aesthetic evaluation of both surgical methods was done by a blinded researcher by photo analysis. For photo analysis, photographs of the recipient area were taken at the beginning and 6 months after the operation with the help of Adobe Photoshop program and evaluated on these photographs. | change in post-op 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| clinical parameters | In the clinical evaluation of both surgical methods, keratinized tissue width parameters were calculated and compared at baseline and pot-op 6 months. | change in post-op 6 months |
