Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Decrease of recession depth, measured with a periodontal probe and defined as a distance from de CEJ to the gingival margin along the tooth axis, at 12 months follow up and expressed in millimeters | — |
Secondary
| Measure | Time frame |
|---|---|
| Percentage of root coverage, assessed using a periodontal probe and by measuring gingival margin positioning before and after 3, 6 and 12 months of the surgical intervention, and expressed in percentage.;Frequency of complete root coverage, clinically assessed by observation of the gingival margin after 3, 6 e 12 months after the surgical intervention.;keratinized tissue width assessed by measuring the width of keratinaized tissue stained with lugol, before the surgery and 3, 6 and 12 month after the surgery and expressed in millimeters.;Gingival or mucosal thickness, assessed by a acrylic guide , measuring distinct regions in each tooth involved in the surgery with a periodontal probe, expressed in millimeters. | — |
