This study was designed to evaluate the effectiveness of subepithelial connective tissue graft (SCTG) and acellular dermal matrix allograft (ADMA) in root coverage procedures and to examine the effect of interdental papilla dimensions on the outcome of root coverage using a new approach. This randomized controlled clinical study included 32 gingival recession defects of at least 2 mm classified as Miller Class I or II. Clinical parameters were measured at baseline and 6, 12, and 24 weeks postsurgery. At baseline, all measured clinical parameters were statistically equivalent between the two groups. With regard to the amount of mean root coverage, no significant difference was found between ADMA (85.42%) and SCTG (69.05%) groups. However, the percentage of complete root coverage was significantly greater in the ADMA group (75.0%, versus 31.3% in the SCTG group). Significant positive correlations were found between papilla height and papilla width and mean root coverage, and papilla height of at least 5 mm was associated with complete root coverage. ADMA seems to be a good substitute for SCTG to treat shallow to moderate gingival recessions. In addition, papilla dimensions, as measured using the new method, can help predict the success of future root coverage.
本研究旨在评估上皮下结缔组织移植（SCTG）和脱细胞真皮基质同种异体移植（ADMA）在牙根覆盖手术中的有效性，并采用一种新方法研究牙间乳头尺寸对牙根覆盖效果的影响。这项随机对照临床研究纳入了32例至少2mm的牙龈退缩缺损，分类为米勒I类或II类。在基线以及术后6周、12周和24周测量临床参数。在基线时，两组间所有测量的临床参数在统计学上相当。关于平均牙根覆盖量，ADMA组（85.42%）和SCTG组（69.05%）之间未发现显著差异。然而，ADMA组的完全牙根覆盖百分比显著更高（75.0%，而SCTG组为31.3%）。发现乳头高度和乳头宽度与平均牙根覆盖之间存在显著正相关，至少5mm的乳头高度与完全牙根覆盖相关。ADMA似乎是治疗轻至中度牙龈退缩的SCTG的良好替代物。此外，使用新方法测量的乳头尺寸有助于预测未来牙根覆盖的成功。
