title: Mucoperiosteal flaps with and without removal of the pocket epithelium.
abstract: The purpose of this study was to clinically evaluate the need for elimination of the pocket epithelium during mucoperiosteal flap surgery aimed at reattachment or readaptation. A split mouth design was used in 13 patients with two bicuspids and two molars included in each quadrant. Two surgical techniques were compared. One of the quadrants received a modified Widman flap with removal of the pocket epithelium, while the contralateral side received a crevicular flap without removing the pocket epithelium. One month after the hygienic phase was completed, the following measurements were taken: Gingival Index, Plaque Index, gingival crevicular fluid flow, mobility, furcation involvement, level of attachment, pocket depth and gingival recession. In addition to these measurements, which were taken immediately prior to the surgery (baseline), 1- and 3-month postsurgical measurements were also taken. Gingival recession was recorded immediately after the flaps were replaced and sutured. All data were analyzed statistically using paired t test and sign test. The biometric results showed that without the removal of the pocket epithelium, good clinical results relative to gain in clinical attachment levels and reduction in probing depth were achieved. Greater gingival recession occurred on the crevicular flap side postsurgically when compared to the modified Widman flap. The other clinical parameters remained the same at the three time intervals. This was true within each technique and when both techniques were compared.
