Gingival recession may result in aesthetically unfavourable effects, difficulty in plaque control, increased susceptibility to root caries, and dentin hypersensitivity.
The aim of this study was to compare the use of modified semilunar techniques with connective tissue and subepithelial connective tissue grafts (Langer) for denuded root surface coverage.
In this randomized clinical trial, fourteen localized recessions of Miller class I to II were treated in 5 subjects. Recessions were randomly treated with modified semilunar techniques (test group) and a subepithelial connective tissue graft (control group). Clinical parameters such as clinical attachment level (CAL), keratinized tissue width (KTW), probing pocket depth (PPD), vertical recession depth (VRD) and recession width (RW)were recorded at base line, 1, 3 and 6 months after surgery and healing index and the subject's satisfaction was evaluated. The repeated measure test and paired-sample t-test were used for statistical analyses by SPSS.
Both methods showed significant improvement in clinical parameters. The healing index (HI) in the test group was a slightly more than the control group in Day 10. Aesthetic VAS (Visual Analogue Scale) levels in the test group were more than the control group in 1, 3 and 6 months (test group, in 1 month 6.57±1.13, in 3 month 7.86±1.07, in 6 month 8.00±0.81. control group in 1 month 5.57±1.13, in 3 month 7.00±1.00, in 6 month 7.14±0.90). The KTW, CAL, VRD and RW level's difference in the test and control group was significant in 6 month compared to the base line (p=0.000).
The present study shows that treatment of Miller Class I and II gingival recession by the modified semilunar technique is acceptable.

牙龈退缩可能导致美学效果不佳、菌斑控制困难、根龋易感性增加以及牙本质过敏。
本研究旨在比较改良半月形技术与结缔组织和上皮下结缔组织移植术（朗格氏法）用于覆盖裸露牙根表面的效果。
在这项随机临床试验中，对5名受试者的14处米勒I至II类局限性牙龈退缩进行了治疗。牙龈退缩随机采用改良半月形技术（试验组）和上皮下结缔组织移植术（对照组）进行治疗。记录基线、术后1、3和6个月时的临床参数，如临床附着水平（CAL）、角化组织宽度（KTW）、探诊袋深度（PPD）、垂直退缩深度（VRD）和退缩宽度（RW），并评估愈合指数和受试者满意度。采用重复测量检验和配对样本t检验，通过SPSS进行统计分析。
两种方法在临床参数上均显示出显著改善。试验组在第10天的愈合指数（HI）略高于对照组。试验组在1、3和6个月时的美学视觉模拟评分（VAS）水平高于对照组（试验组，1个月时为6.57±1.13，3个月时为7.86±1.07，6个月时为8.00±0.81；对照组，1个月时为5.57±1.13，3个月时为7.00±1.00，6个月时为7.14±0.90）。与基线相比，试验组和对照组在6个月时的KTW、CAL、VRD和RW水平差异有统计学意义（p = 0.000）。
本研究表明，改良半月形技术治疗米勒I类和II类牙龈退缩是可行的。
