Predictable root coverage and good colour match are the major therapeutic end points in the treatment of gingival recession. Alloderm has been used as a substitute to connective tissue graft, but its colour match in populations with a high degree of melanin pigmentation has not been extensively studied. The aim of this study was to evaluate the effectiveness of an Acellular dermal matrix graft for root coverage procedures and to objectively analyze the post-operative esthetics using a Visual Analog Scale (VAS).
Both male and female patients were selected, aged 20-50 years presenting with aesthetic problems due to the exposure of recession defects when smiling. A total of 14 patients contributed to 15 sites, each site falling into Miller's class I or class II gingival recession.
A total of 15 sites were treated and a mean coverage of (85.56±21.70 and 83.33±21.82%) was obtained at the end of 3(rd) and 12(th) month respectively. A mean VAS score of 7.93±1.03 and 8.13±0.99 (3(rd) and 12(th) month) and 5.73±0.70 and 6.87±0.83 (3(rd) and 12(th) month) was obtained when the colour match recorded by the patients and an independent observer, respectively.
The study showed that acellular dermal matrix graft (alloderm) may be successfully used to treat gingival recession, as adequate root coverage may be predictably obtained. The grafted areas underwent melanization from the 6(th) month onwards and complete blending with the adjacent sites was obtained at 1 year.
可预测的牙根覆盖和良好的颜色匹配是牙龈退缩治疗的主要治疗终点。脱细胞真皮基质已被用作结缔组织移植的替代物，但在黑色素沉着程度高的人群中其颜色匹配尚未得到广泛研究。本研究的目的是评估脱细胞真皮基质移植用于牙根覆盖手术的有效性，并使用视觉模拟量表（VAS）客观分析术后美学效果。
选择年龄在20 - 50岁的男性和女性患者，这些患者因微笑时牙龈退缩缺陷暴露而存在美学问题。共有14名患者的15个部位参与研究，每个部位均属于米勒I类或II类牙龈退缩。
共治疗了15个部位，分别在第3个月和第12个月末获得的平均覆盖率为（85.56±21.70%和83.33±21.82%）。患者记录的颜色匹配情况和独立观察者记录的颜色匹配情况在第3个月和第12个月时的平均VAS评分分别为7.93±1.03和8.13±0.99，以及5.73±0.70和6.87±0.83。
该研究表明，脱细胞真皮基质移植（脱细胞真皮基质）可成功用于治疗牙龈退缩，因为可以可预测地获得足够的牙根覆盖。移植区域从第6个月开始出现黑色素沉着，1年后与相邻部位完全融合。
