Human cultured gingival epithelial sheets were used as an autologous grafting material for regenerating gingival tissue in the maxillary left and mandibular right quadrants of a patient with chronic desquamative gingivitis. Six months post-surgery in both treated areas, there were gains in keratinized gingiva and no signs of gingival inflammation compared to presurgery. In the maxillary left quadrant, preoperative histopathologic findings revealed the epithelium was separated from the connective tissue and inflammatory cells were extensive. After grafting with the gingival epithelial sheets, inflammatory cells were decreased and separation between epithelium and connective tissue was not observed. The human cultured gingival epithelial sheets fabricated using tissue engineering technology showed significant promise for gingival augmentation in periodontal therapy. [ABSTRACT FROM AUTHOR]
