Digital Color Analysis of the Graft and Recipient Site After Free Gingival Graft Surgery

NCT07199686 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 50

No results posted yet for this study

Summary

This study evaluates gingival color following Free Gingival Graft (FGG) surgery using polarized digital photography to objectively analyze grafted and adjacent tissues. Conventional verbal descriptors (e.g., pale pink, salmon pink) lack precision; therefore, digital colorimetry provides objective, non-contact, and reproducible measurements. The protocol utilizes the CIELab system with standardized color disks and polarization to document postoperative color changes accurately.

The study objectives are: (1) to determine CIELab color values of FGG-treated gingiva in patients who underwent conventional surgery at least six months earlier; (2) to assess the influence of age, sex, time since surgery, and gingival thickness on these values; and (3) to compare graft color with adjacent gingiva.

Hypothesis: In FGG-treated patients, graft CIELab color values are unaffected by age, sex, postoperative duration, or gingival thickness.
