简要总结
Patients with high standards of oral hygiene frequently search for buccal gingival recession (GR) treatment due to cervical wear, root sensitivity and compromising aesthetics. The cervical lesion (NCCL) is commonly produced by improper toothbrushing techniques, sharing the same etiology of GR. Many different surgical approaches have been described. The association of a graft to the coronally advanced flap had demonstrated the best long-term outcome for root coverage. But, substitutes for the autogenous graft must be studied. Therefore, the aim of this clinical trial was to investigate the effectiveness of the acellular dermal matrix graft (ADMG) in root coverage associated with a previous restored cervical lesion or not.
Material and methods: Seventeen individuals with bilateral GR were included in the study. At one side, the GR must present a previously restored cervical lesion, as the test group (TG). The contralateral arch, must present GR with an intact root surface (CG). All patients were treated with the extended flap technique associated with the ADMG. All clinical parameters were assessed at baseline and 6-months postoperative.

研究组 & 干预措施
Test Group
Active Comparator: gingival recession with a previous restored cervical lesion
the aim of this study is to compare if the acellular dermal matrix graft is as efficient as a substitute for the connective graft used in root coverage of gingival recessions with non carious cervical lesions.
干预措施: Root coverage with extended flap technique and acelular dermal matrix (Procedure)
Control Group
the aim of this study is to compare if the acellular dermal matrix graft is as efficient as a substitute for the connective graft used in root coverage of gingival recessions with non carious cervical lesions. The control group had no cervical lesion, and was treated with the same technique as the acelular dermal matrix graft
干预措施: Root coverage with extended flap technique and acelular dermal matrix (Procedure)
结局指标
主要结局
Root coverage
时间窗: 6 months
Root coverage is measured by the difference between the gingival recession height at 6 months and baseline
次要结局
- Keratinized tissue(6months)
