Gingival recession is an apical shift of the gingival margin with exposure of the root surface to the oral cavity, which creates an esthetic problem. The present study was attempted to compare vestibular incision subperiosteal tunnel access (VISTA) with and without advanced platelet-rich fibrin (A-PRF) in the treatment of Miller Class I gingival recessions. A total of 24 patients were assigned randomly to either the test group (VISTA with A-PRF) or the control group (VISTA alone). Clinical parameters like recession depth, recession width, clinical attachment loss, width of keratinized gingiva, gingival thickness, and probing depth were recorded at baseline and at 3 and 6 months postoperatively. Intergroup comparison of mean root coverage (RC) in mm, %RC, change in width of keratinized gingiva and clinical attachment gain revealed no statistically significant difference (P > .05). Change in gingival thickness showed statistically significant improvement in test group. Within the limitations of this study, both treatment options (VISTA with A-PRF and VISTA alone) have resulted in predictable and comparable RC, with increased gingival thickness in the test group.
牙龈退缩是牙龈边缘的根尖移位,导致牙根表面暴露于口腔中,从而造成美观问题。本研究旨在比较带或不带先进富血小板纤维(A-PRF)的牙槽骨骨膜隧道式龈瓣转移术(VISTA)治疗 Miller Ⅰ类牙龈退缩的疗效。共 24 名患者随机分为实验组(VISTA+A-PRF)和对照组(VISTA 单独治疗)。在基线和术后 3 个月和 6 个月时记录临床参数,如牙周袋深度、牙周袋宽度、临床附着丧失、角化龈宽度、牙龈厚度和探诊深度。在平均根覆盖(RC)mm、%RC、角化龈宽度变化和临床附着获得的组间比较中,差异无统计学意义(P>0.05)。实验组的牙龈厚度显示出统计学上显著的改善。在本研究的限制范围内,两种治疗方案(VISTA+A-PRF 和 VISTA 单独治疗)均能获得可预测且可比的 RC,并使实验组的牙龈厚度增加。
