The use of periosteum as a pedicle graft in the treatment of gingival recession defects is a recent advancement. The subepithelial connective tissue graft (SCTG) is considered the gold standard for the treatment of gingival recession defects. The present randomized controlled trial was done to compare periosteal pedicle graft (PPG) with SCTG for the treatment of gingival recession defects.
10 males and 10 females between the ages of 16 and 40 years (mean age 25.2 years) with Miller's Class I and II recessions ≥3 mm participated in this one-year clinical study. They were assigned randomly to test group (PPG) and control group (SCTG). Results were evaluated based on parameters measuring patient satisfaction and clinical outcomes associated with two treatment procedures. Significance was set at p < 0.05.
At the end of the study, the defect coverage was 3.1 ± 0.13 mm or 92.6% in the test group compared to the control group in which the defect coverage was 2.70 ± 0.11 mm or 88.5%. The difference between the two groups was statistically significant (p < 0.0001). The average residual defect was comparable between the two groups, i.e. 0.3 ± 0.67 and 0.5 ± 0.84 in the PPG and SCTG group respectively. The test group was rated higher in terms of overall patient satisfaction (p < 0.02) and comfort during and after the procedure (p < 0.001).
PPG and SCTG have comparable clinical effectiveness, but PPG is superior to SCTG in terms of patient-centred outcomes, reflecting improved patient comfort and overall patient satisfaction.
使用骨膜作为带蒂移植物治疗牙龈退缩缺陷是最近的一项进展。上皮下结缔组织移植物（SCTG）被认为是治疗牙龈退缩缺陷的金标准。本随机对照试验旨在比较骨膜蒂瓣移植（PPG）和 SCTG 治疗牙龈退缩缺陷。
10 名年龄在 16 至 40 岁之间（平均年龄 25.2 岁）的男性和 10 名女性，患有 Miller Ⅰ类和Ⅱ类退缩≥3mm，参与了这项为期一年的临床研究。他们被随机分配到实验组（PPG）和对照组（SCTG）。结果根据评估患者满意度和与两种治疗程序相关的临床结果的参数进行评估。设 p < 0.05 为有统计学意义。
研究结束时，实验组的缺陷覆盖率为 3.1 ± 0.13mm 或 92.6%，而对照组的缺陷覆盖率为 2.70 ± 0.11mm 或 88.5%。两组之间的差异具有统计学意义（p < 0.0001）。两组之间的平均残余缺陷相当，即 PPG 和 SCTG 组分别为 0.3 ± 0.67mm 和 0.5 ± 0.84mm。实验组在总体患者满意度方面（p < 0.02）和治疗过程中和治疗后的舒适度方面（p < 0.001）的评分更高。
PPG 和 SCTG 具有相当的临床效果，但 PPG 在以患者为中心的结果方面优于 SCTG，反映了患者舒适度的提高和总体患者满意度的提高。
