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.

|---|---|---|---|
| Test Group | Active Comparator | 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. |
|
| Control Group | Placebo Comparator | 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 |

| Root coverage with extended flap technique and acelular dermal matrix | Procedure | At one side, the root coverage have been done with a extended flap technique and acellular dermal matrix and there was no cervical lesion. At the other side, the same technique was performed, but the gingival recession was associated with a noncarious cervical lesion. |
| Measure | Description | Time Frame |
|---|---|---|
| Root coverage | Root coverage is measured by the difference between the gingival recession height at 6 months and baseline | 6 months |
| Measure | Description | Time Frame |
|---|---|---|
| Keratinized tissue | The difference between keratinized tissue width and depth at 6 months and at baseline. | 6months |
