Gingival Unit Graft Versus Free Gingival Graft: 18-Month Digital Color Analysis
15. juli 2026 opdateret af: Sanubar Shakiliyeva, Bezmialem Vakif University
Clinical Outcomes and Digital Color Stability of Gingival Unit Graft Versus Free Gingival Graft: An 18-Month Comparative Digital Photographic Color Analysis Study
The purpose of this retrospective clinical study is to compare the long-term aesthetic integration and clinical outcomes of two periodontal plastic surgery techniques: Gingival Unit Grafting (GUG) and Free Gingival Grafting (FGG).
The study evaluates the effectiveness of these procedures in increasing keratinized tissue width and assesses the color integration of the grafted tissues with the surrounding gingiva over an 18-month follow-up period using objective digital color analysis based on CIE Lab and RGB parameters.

Detaljeret beskrivelse
This single-center retrospective study included patients treated with either Gingival Unit Grafts (GUG) or Free Gingival Grafts (FGG) for the management of Cairo Type 2 and Type 3 gingival recessions between March 2022 and December 2022.
Clinical and photographic records obtained at baseline and during follow-up visits up to 18 months were retrospectively analyzed.
The primary outcome was the evaluation of color integration of the grafted tissues using objective digital color analysis based on CIE Lab and RGB parameters.
Secondary outcomes included changes in keratinized tissue width.
The aim of the study was to compare the long-term aesthetic integration and clinical performance of GUG and FGG and to determine which technique provides superior color matching with the surrounding tissues.

Aesthetic Integration (Color Evaluation)
Tidsramme: Baseline and 18 months post-surgery
|
Objective assessment of color integration between the grafted tissue and the surrounding gingiva using digital color analysis.
Color parameters were evaluated based on the CIE Lab* color space system and RGB color channels obtained from standardized clinical photographs.
The degree of color matching between grafted and adjacent tissues was assessed over the follow-up period.
