Two Different Graft Harvesting Techniques Applied in Localized Gingival Recessions
Study Details
Study Description
Brief Summary
The primary purpose of this study is to compare the root coverage rate of the gingival unit-shaped connective tissue graft, obtained by intraoral de-epithelization, with the traditional de-epithelialized free gingival graft in localized recessions of anterior and premolar teeth. In addition, it is aimed to compare the postoperative gingival thickness between the two techniques. The secondary aim is to search the effects of both techniques on periodontal parameters and to evaluate patient-centered outcomes.

| Experimental: De-epithelialized gingival unit graft In this split-mouth randomized controlled trial, the coin toss method will determine test and control groups. In both groups, connective tissue graft with a trapezoidal flap design will be applied to the recession area. To obtain the connective tissue graft, the gingival unit graft will be de-epithelialized in the test group. |
Procedure: Coronally advanced flap with connective tissue graft
In both groups, connective tissue graft with a trapezoidal flap design will be applied to the recession area.

Outcome Measures
Primary Outcome Measures
- Root coverage percentage [Postoperative 6th month]
The comparison of the postoperative recession depth to the initial recession depth
- Gingival thickness [Preoperative and postoperative 6th month]
Gingival thickness in the mid-buccal of the recession defect measured with an endodontic spreader and digital recordings
Secondary Outcome Measures
- Recession width [Preoperative and postoperative 6th month]
Recession width measured at the cemento-enamel junction
- Probing depth [Preoperative and postoperative 6th month]
Probing depth measured at the mid-buccal of the recession defect
- Clinical attachment loss [Preoperative and postoperative 6th month]
Clinical attachment loss measured at the mid-buccal of the recession defect
- Keratinized gingiva width [Preoperative and postoperative 6th month]
Mid-buccal gingival width measured with a periodontal probe
- Vestibular depth [Preoperative and postoperative 6th month]
The distance from the gingival margin to the greatest concavity of the mucosal fold
- Pain perception [Postoperative 1st week]
Visual analog scale where higher scores mean a worse outcome and has a minimum value of 0 and a maximum value of 10
- Bleeding related to the procedure [Postoperative 1st week]
Bleeding evaluated by a dichotomous index
