Aesthetic Evaluation of Free Gingival Graft Applied By Partial De-Epithelialization and Free Gingival Graft Applied By Conventional Method: A Randomized Controlled Clinical Study

Abstract

AbstractObjective:The aim of this clinical study is to compare the partially de-epithelialized free gingival grafts (d-FGG) with the conventional free gingival grafts (FGG) aesthetically with the help of photographic analysis and visual evaluation (VAS).Materials and Methods: A total of 30 defects were treated in 15 patients with attached gingiva insufficiency. In the split-mouth study, d-FGG were applied on one side (Test group), while FGG were applied on the contralateral side (Control group). Results of clinical periodontal parameters were evaluated in 6-month follow-up, and aesthetic evaluation results were evaluated in 1, 3, and 6 months follow-up.Results:Among the periodontal clinical parameters examined, only the keratinized tissue width (KT) was found to be statistically significantly higher in the test group compared to the control group. In photo analysis evaluation, a significant difference was found between both groups at the 3rd month. In visual evaluation, there was no significant difference between the two groups in the time periods examined.Conclusion:d-FGG and FGG are equivalent to each other in terms of aesthetic harmony and clinical parameters. d-FGG have become a preferable option in mucogingival surgery alone or in combination with other techniques, providing aesthetic success.Clinical Relevance:The free gingival graft has a whiter appearance that is not compatible with the recipient site, while the de-epithelialized gingival graft and connective tissue graft have a pinker appearance that is compatible with the recipient site.Partially de-epithelialized free gingival graft is a method with acceptable aesthetic results.
